What I Work On

Over the years, I’ve worked on systems involving:

Large-scale distributed backend systems
Low-latency request processing
High-QPS APIs
Real-time optimization systems
ML/CVR prediction pipelines
AI infrastructure and automation tooling
Performance engineering and infra optimization
Data-intensive backend architectures

Most of my work has focused on solving problems where:

scalability matters,
latency matters,
reliability matters,
and infrastructure efficiency matters.

I enjoy working on systems that operate under real production constraints and require practical engineering tradeoffs at scale.

Areas I’m Currently Exploring

Lately, I’ve been spending more time exploring the intersection of:

AI systems
distributed infrastructure
backend optimization
and production-scale ML platforms.

Some areas I’m currently interested in:

AI Infrastructure

inference systems
orchestration
model serving
prompt pipelines
scalable AI tooling

ML & Prediction Systems

CVR prediction systems
feature pipelines
production inference flows
experimentation frameworks

Backend & Distributed Systems

concurrency
caching systems
event-driven architectures

observability
scaling strategies

Tech Stack

Some technologies I frequently work with:

Python
Java
Redis
SQL
Linux systems
REST/gRPC architectures
Distributed caching systems
Cloud infrastructure
Performance optimization tooling

Currently spending more time improving my:

Go
Rust
AI systems engineering skills

Why I Built My Portfolio Website

I recently launched my personal website:

👉 https://swapnanilsaha.com

The goal is to create a central place for:

projects
engineering writeups
architecture ideas
experiments
future AI infrastructure work

I also wanted a clean place to document lessons from building production systems and exploring modern AI infrastructure.

Topics I’ll Be Writing About

Going forward, I plan to write about:

scaling backend systems
low-latency engineering
distributed systems architecture
AI infra tooling
production ML systems
performance optimization
backend engineering patterns
practical engineering lessons from real systems

Open to Connecting

I enjoy discussing:

distributed systems
backend architecture
AI infrastructure
performance engineering
scalable systems design
