New Year, New You Portfolio Challenge Submission

This is a submission for the New Year, New You Portfolio Challenge Presented by Google AI

About Me

I’m a developer who enjoys building things that sit at the intersection of engineering, design, and product thinking.
Currently 4th year student at IIT BHU, India ready to be in the industry from the upcoming months.

This portfolio is not just a showcase of projects, but a reflection of how I think, build, and iterate.

How I Built It

I built it using the following tech stack :

Next.js (App Router) — server components, layouts, and streaming
Prisma (v6) + Prisma Data Platform (Accelerate) — database access with performance optimizations
PostgreSQL : persistent data layer
Docker : production-ready builds
Tailwind CSS and Shadcn/UI : consistent and scalable UI
Google Cloud Run : container-based deployment
Google AI (Gemini API) : Built entire chatbot using Gemini that has been trained over my data and you can talk all about me, AI-powered summaries (for individual projects summary or summary in Currently Reading Section), Gemini resulted to be very powerful and performed exceptionally well.
Antigravity IDE : The entire portfolio has been developed on Antigravity and it has been proved to be very helpful in design decisions, doing many heavy lifting and helping me go 10x faster.

Design Decisions

From the start, I wanted this portfolio to feel quiet, intentional, and honest.
Instead of overloading it with animations or visual noise, I focused on clarity, spacing, and hierarchy with UX being the primary focus.

Every click must be intuitive about it's action.

Early in the design phase, I used Antigravity as a thinking partner to explore layout directions, interaction patterns, and content structure. It helped me quickly validate instincts, question assumptions, and refine ideas before committing them to code.

Some of the key design decisions included:

A minimal, content-first layout to reduce distraction
Subtle motion and transitions used only where they add meaning
A restrained color palette to keep the focus on projects and writing
Clear separation between projects, blogs, and experiments so visitors can quickly find what they’re interested in

The goal was not to impress instantly, but to feel thoughtful and trustworthy as someone spends time exploring.

Development Process

I built the portfolio iteratively, treating it as a real product rather than a static site.

I started by setting up the core architecture with Next.js (App Router), Prisma, and PostgreSQL, focusing on clean data models, routing, and server boundaries before moving to UI polish.
Using Server Components and Server Actions helped keep logic close to the data and reduced client-side complexity. During this phase, Antigravity acted as a reasoning aid for architectural trade-offs and edge cases, particularly around rendering and data flow.
For deployment, I chose Google Cloud Run with Docker instead of a managed abstraction. This pushed me to understand build-time vs runtime execution, environment variables, and Prisma behavior in production. Antigravity helped validate steps during debugging, while final fixes came from hands-on testing and logs.

After launch, I refined interactions and handled runtime edge cases - treating deployment challenges as part of the learning process rather than setbacks.

What I'm Most Proud Of

It was fascinating to think about how I want to present myself on internet but happily I was able to do that, also I faced some technical challenges and learnt from them including :
