Supported Go microservices to unblock cross-functional full-stack work.
@ Mercari, Inc. · Tokyo
Delivered 3+ production features in React and TypeScript 50% faster than the estimated timeline. Contributed to the web-wide migration from Gatsby to Next.js.
@ IIIT Gwalior
Graduated from the Indian Institute of Information Technology, Gwalior. Coursework across data structures, algorithms, OOP, databases, operating systems, and software engineering — and a steady habit of competitive programming on the side.
@ Shopout · Remote
Built a live-stream platform on Agora SDK and Firebase serving 300+ users. Improved invoice-generation APIs with Node.js and MongoDB, automating client-side PDF creation.
A small archive of projects I've shipped beyond the day job — from real-time game backends to hackathon-winning developer tools.
A full-stack realtime pictionary game in React, Node.js, and WebSockets. Built session management, user matching, and synchronized game state from scratch — and offloaded image processing onto Web Workers for a snappy UI. Containerized with Docker and deployed to Google Cloud Run.
A unified developer dashboard that aggregates stats from GitHub, CodeChef, and Codeforces, backed by a custom MongoDB-driven ranking algorithm. Built fullstack and took 1st of 50+ teams at Hackrocket '22.
A Google Keep–inspired notes app for Android — material design, color-coded notes, and Firebase sync. Built in Kotlin; the most-starred repo on my GitHub.
A CLI for detecting plagiarism across source-code files, built on latent semantic analysis and bespoke information-retrieval techniques. Python end-to-end.
A small web app I built to drill Japanese kana and vocabulary while settling into Tokyo. Light, fast, deployed to Netlify — and quietly useful on my morning commute.
A toolset honed across systems engineering, immersive rendering, and design-system architecture — calibrated for high-fidelity output.
Shipping marketplace-scale React and Next.js experiences in TypeScript — typed, performance-tuned, and tested end-to-end.
Real-time features wired through WebSockets, Go and Node.js microservices, MongoDB, and Docker-containerized deployments.
Algorithms, system design, and the discipline of well-tested, performant code. 500+ LeetCode solved; CI/CD in muscle memory.
Direct line for collaborations, commissions, or quiet conversations about the future of the web.
