About Me: Afee Muhammod Wafy

Afee Muhammod Wafy — Sat, 12 Sep 2026 14:39:20 +0000

Hello, I'm Wafy — A Web Developer & Science Student

My name is Afee Muhammod Wafy, though most people call me Wafy.

Quick Facts & Identity

Full Name: Afee Muhammod Wafy
Location: Rangpur, Bangladesh
Current Status: Web Developer & Science Student
Education: Higher Secondary Certificate (HSC), Science
Main Interests: Web Development, Cybersecurity, Python, JavaScript, and AI

I am a science student and self-taught web developer from Bangladesh. I build web applications, developer utilities, and security-focused tools while learning through practical work and experimentation.

My interest in technology has always been closely connected to curiosity. I like understanding how things work, why they work the way they do, and what happens behind the scenes.

Over time, that curiosity led me towards programming and web development.

A Little About Me

I have always been interested in understanding things rather than simply using them.

My background as a science student has influenced the way I approach problems. I naturally try to break a problem into smaller parts, understand the logic behind it, and then work towards a solution.

Programming gave me a practical way to apply that way of thinking.

When I started learning web development, I did not want to limit myself to tutorials and examples. I wanted to build things of my own and understand what happens when different parts of an application come together.

That approach has led me to work with frontend development, backend development, APIs, databases, security concepts, and browser-based applications.

What I Do

My work mainly revolves around web development and practical software projects.

I have worked with technologies such as HTML, CSS, JavaScript, Python, Flask, C, Git, GitHub, Linux, PostgreSQL, and SQLAlchemy.

I have also worked with REST APIs, responsive interfaces, UI/UX layouts, API integration, and basic web security.

I enjoy building projects where I can learn something by actually implementing it rather than only studying the theory.

Some of the areas I have worked with include:

Frontend Web Development
Full-Stack Web Development
Python & Flask
JavaScript
REST API Integration
PostgreSQL & SQLAlchemy
Responsive UI Development
Web Security Basics
Developer Utilities
Git & GitHub
Linux
UI/UX Layouts

Projects I Have Built

Building projects has been one of the most important parts of my development journey.

Each project has helped me explore a different area of development and understand how different technologies and concepts work together.

WafyShield

WafyShield is a web security audit scanner focused on checking common security-related configurations of websites.

It checks security-related configurations such as HTTPS, TLS, HSTS, Content Security Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, and cookie security attributes.

The application generates a security score along with PASS, WARNING, and FAIL results and provides recommendations for detected issues.

While working on it, I explored concepts such as web security, request isolation, SSRF protection, security headers, redirects, and privacy-conscious data handling.

WafyURL

WafyURL is a full-stack URL shortening and link management application built with Python, Flask, PostgreSQL, and SQLAlchemy.

It includes features such as custom URL aliases, password-protected links, QR code generation, click analytics, visitor telemetry, and bulk processing.

Working on this project gave me practical experience with backend development, database indexing, connection pooling, HTTP redirects, authentication flows, and handling analytics data without storing raw IP addresses.

It also helped me understand how different parts of a backend application work together beyond simply creating routes and returning responses.

WafyDev

WafyDev is a privacy-focused developer utility suite that works directly in the browser.

It includes several browser-based tools such as:

Password Generator
QR Generator
Typing Test
Study Timer
Markdown Preview
Note Taker
Countdown
Text Utilities
Color Palette

The project is built using HTML, CSS, and Vanilla JavaScript without external libraries.

While building it, I worked with browser-native APIs, local storage, client-side processing, Markdown sanitization, cryptographically secure random number generation, and timer accuracy.

The project also gave me a better understanding of how much can be accomplished using the browser itself without depending heavily on external services.

AstroWafy

AstroWafy is an educational astronomy project that integrates NASA's Open APIs to present astronomy-related information in a more accessible way.

It includes features such as:

NASA APOD API integration
English and Bengali content
Date-based navigation
High-resolution image handling
Download functionality
Local caching
Client-side content sanitization

While working on AstroWafy, I explored asynchronous JavaScript, API integration, AbortController, Blob handling, local storage, and bilingual interfaces.

It was also an opportunity to work with asynchronous requests and handle situations where users interact with an application faster than an API response can complete.

What Building These Projects Has Taught Me

Building projects has taught me things that are difficult to fully understand through theory alone.

While working on different applications, I have encountered problems involving API requests, asynchronous operations, database queries, authentication, browser limitations, security considerations, performance, and user experience.

Sometimes the solution was simple. Other times, it required reading documentation, testing different approaches, finding bugs, and understanding why something was not working.

That process has become an important part of how I learn.

I have also learned that making an application work is only one part of development. Details such as security, privacy, performance, error handling, usability, and maintainability also matter.

My Approach to Development

I prefer learning by building.

When I learn a new concept, I try to understand where it can actually be used and then apply it in a project.

I also prefer using a simple solution when a simple solution is appropriate. I do not think every problem needs a complicated stack or a large number of dependencies.

At the same time, working on different types of projects has helped me understand when a more structured approach is necessary.

For me, development is not only about writing code. It is also about understanding the problem, choosing an appropriate approach, testing it, finding what does not work, and improving the result.

Security and Privacy

Security has become an important area of interest in my development work.

Some of my projects involve security-related functionality, including website security checks, password protection, secure random number generation, authentication, and privacy-conscious telemetry.

Working on these projects has helped me understand that security is not something that should simply be considered at the end of development.

Even a relatively small application can involve security considerations when it handles user input, authentication, external requests, or data.

Learning Through Building

Alongside practical development, I have completed courses and certifications in areas related to technology.

Some of my certifications include:

Digital Skills: Artificial Intelligence — FutureLearn & Accenture, 2026
Intro to Cyber Security — FutureLearn & The Open University, 2026
Basics of Python — UniAthena, 2026

These have given me additional exposure to artificial intelligence, cybersecurity, and Python alongside my hands-on development work.

Education

I am a science student at Gangachara Govt. College, where I have been studying for my Higher Secondary Certificate (HSC).

Before that, I completed my Secondary School Certificate (SSC) from Gangachara Govt. Model High School in the Science group.

My academic background and development work have existed alongside each other. Science has influenced my analytical way of thinking, while programming has given me a practical way to apply that thinking.

The Person Behind the Code

Technology is an important part of what I do, but I am still a student and a learner.

I do not consider myself someone who already knows everything about development.

There are still many concepts I am learning and many problems that take time to understand.

What matters to me is the process of figuring them out.

I enjoy starting with something I do not understand, experimenting with it, making mistakes, reading documentation, and eventually developing a clearer understanding of how it works.

That curiosity remains one of the biggest reasons I enjoy programming.

Build a Lightweight Web Security Scanner with Next.js: Meet WafyShield 🛡️

Afee Muhammod Wafy — Wed, 09 Sep 2026 15:00:38 +0000

Web security shouldn't be complicated, yet most enterprise-grade security auditing tools lock basic checks—such as SSL validation, security header analysis, and cookie security—behind confusing interfaces or expensive paid subscriptions.

In order to address this, I created WafyShield, a lightweight, fast, and serverless web security scanner designed to evaluate any public website in seconds with a strong focus on privacy and zero server-side storage.

🌐 Live Application & Source

Live Application: shield.amwafy.xyz
GitHub Repository: github.com/afeemuhammodwafy1/wafyshield

⚡ Key Features

HTTPS & SSL Security Check: Confirms whether a website properly enforces secure transport and inspects TLS certificate details (such as issuer, subject, and expiration dates).
Security Headers Checker: Audits OWASP-recommended headers like HSTS, Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
Cookie Security Audit: Detects cookies set by the server and verifies essential flags like Secure, HttpOnly, and SameSite.
Instant Security Score & Risk Level: Calculates a clear 0–100 score alongside an overall risk tier (Low, Medium, High, or Critical).
Remediation Guides: Provides copy-pasteable fix recommendations for every warning or failed check.
Client-Side History & JSON Export: Stores recent scan reports locally in the browser (localStorage) and allows exporting full reports as JSON.
Responsive UI & Dark Mode: A clean, green-themed interface built with a built-in dark/light mode toggle.

🛠️ Architecture & Tech Stack

Framework: Next.js 14 (Pages Router) for fast routing and serverless efficiency.
Styling: Scoped CSS-in-JS (styled-jsx) for clean component-level design without heavy UI libraries.
Backend & Compute: Next.js Serverless API Routes utilizing Node.js native fetch and tls modules.
Hosting: Vercel Serverless Functions to ensure minimal latency and zero maintenance overhead.

💡 Engineering Highlights

1. Guarding Against SSRF (Server-Side Request Forgery)

Since the server performs fetch requests on behalf of users, malicious inputs could potentially target internal or private network ranges (like localhost or 127.0.0.1). To prevent this abuse, the URL normalizer strictly blocks private and local IP addresses before making any outbound network calls.

2. Direct TLS Socket Inspection

Instead of relying on heavy third-party packages to inspect SSL certificates, WafyShield connects directly to port 443 using Node.js's built-in tls module to extract certificate metadata securely and efficiently.

3. Lightweight In-Memory Caching

To minimize redundant external requests and speed up response times for repeated lookups, an in-memory cache with a Time-To-Live (TTL) mechanism was implemented directly inside the serverless execution environment.

Building WafyURL: A High-Performance URL Shortener with Real-Time Analytics & Security

Afee Muhammod Wafy — Mon, 24 Aug 2026 09:14:37 +0000

Link management shouldn't be complicated since most URL shorteners put essential features—such as custom slugs, password protection, and analytics—behind costly monthly paywalls.

In order to deal with this, I created WafyURL, a fast, secure and fully featured link management platform which is designed with a focus on speed and privacy.

🌐 Live Application & Source

Live Application: url.amwafy.xyz
GitHub Repository: github.com/afeemuhammodwafy1/wafyurl

⚡ Key Features

Custom Slugs: Create branded and easy-to-remember links in order to enhance click-through rates.
Detailed Analytics: Monitor the total number of clicks, geographic location, device types, operating systems, and referrers without using heavy third-party trackers.
Password Protection: Include an optional password to secure sensitive destinations using SHA-256 encryption.
Auto-Expiration: Set links to expire by themselves after 1 hour, 24 hours, 7 days, or 30 days.
Bulk Shortening: Generate multiple shortened URLs at the same time with just one click.
QR Code Generation: Instantly generate downloadable QR codes on the client side for use in printing and marketing campaigns.
Destination Preview: Extract Open Graph metadata on the server side to preview destination links before redirection.

🛠️ Architecture & Tech Stack

Backend: Python 3.11 together with Flask, which offers a lightweight and modular routing base.
Database: PostgreSQL running on Neon Serverless, managed via Flask-SQLAlchemy.
Hosting & Compute: Vercel Edge Serverless Functions to achieve minimal global latency.
Frontend: Semantic HTML5, Vanilla JavaScript, and modern CSS3 Glassmorphism without employing heavy frameworks.

💡 Engineering Highlights

1. Optimising the Database for a Serverless Environment

Since serverless backends tend to open and close connections rapidly, this can cause standard database pools to become exhausted. To make sure response times remain stable during traffic surges, persistent connection pooling, connection recycling, and automated pre-pings were configured.

2. Zero-Dependency Client Execution

Key frontend features—such as dynamic QR code rendering and the collapsible FAQ accordion—are handled natively instead of relying on large third-party JavaScript libraries. This ensures minimal bundle sizes and faster Time-to-Interactive (TTI).

3. Integrated Security & Abuse Prevention

To ensure platform stability, a sliding-window rate limiter based on IP addresses prevents spam and brute-force requests. Furthermore, password-protected endpoints verify SHA-256 hashes prior to executing any redirect logic.
