Journey

From intern to shipping production systems at scale. A timeline of technical growth and ownership.

2024 - Present

The Software EngineerOmaza

SDE-1Omaza
  • Worked on performance-critical user-facing webview frontends implementing cross-provider live streaming with WebRTC, and real-time chats with optimistic updates handling 25k+ requests / second.
  • Implemented a real-time calling and chat system, rich analytics graphs and maps in an internal admin dashboard for lead management — resulting in a 60-65% efficiency increase in acquiring new leads for the sales team.
  • Built fully end-to-end type-safe internal tooling to manage two-way callbacks between webview and native layer using the window.postMessage bridge, improving reliability and developer velocity across teams.

Late 2024

The Open Source MaintainerPujo Atlas

Frontend LeadPujo Atlas
  • Built and scaled a Google Maps-based navigation web app to help users find the nearest Durga Pujo pandals across Kolkata, driving 872.49K searches and 114.83K journeys in just 5 days.
  • Designed a location-aware ranking algorithm that prioritizes results by user proximity (not global popularity), supporting 10.8K visitors/day during peak Pujo traffic.
  • Mentored students during Hacktoberfest 2024 in writing clean, scalable and maintainable code with strict code reviews and constructive feedback.

Early 2024

The InternZscaler

Frontend InternZscaler
  • Migrated the frontend data layer to modern fetching + caching using Axios and React Query, improving loading states across 100+ components while removing redundant logic to boost overall performance.
  • Standardized build tooling across a micro-frontend monorepo by unifying on Webpack (replacing Vite/Rollup), cutting build times by 20% and improving maintainability across 15+ applications.
  • Implemented code-splitting to reduce initial JavaScript bundle size by 30%, leading to faster first-load performance and lower user wait time.
  • Improved React front-end test coverage from 75% to 88% using Jest + React Testing Library, validated via SonarQube.

2022 - 2023

The Full-Stack InternARS Inventif

Full-Stack InternARS Inventif
  • Developed a facial recognition-based attendance system using Next.js, TypeScript, and PostgreSQL.
  • Created an LMS platform integrated with attendance tracking and video storage in AWS S3.

Selected Works

Products and experiments I've shipped — from festival-scale traffic to quiet beta launches.

Outside work

Chess boards, manga stacks, and Polaroids — what I reach for off the clock.

Let's Connect

Feel free to reach out for collaborations, questions, or any exciting opportunities. Always happy to talk shop about frontend systems, WebRTC, or shipping things that scale.
