I'm Pushpraj Singh, a software engineer in Delhi with 3+ years in production React. I build fast, durable software end-to-end — from architecture and APIs to the product people use — for fintech, AI and creator companies.
Selected work
Five products I've built or rebuilt, from public marketing sites to real-time platforms with 100K+ users. Open one to see what I did and what changed.
SEO-optimised marketing site
Delivered a fully responsive, SEO-first public website powered by Strapi CMS. Lighthouse score improved from 62 → 88, and the marketing team can now update content independently — cutting engineering involvement by ~60–70%.
Built with Next.js, TypeScript, Tailwind CSS, Strapi
How I work
I think in systems, not shortcuts.
Architecture before implementation
The cost of a bad decision multiplies with every line of code added on top of it. I define contracts, data flow, and system boundaries before writing the first line.
Performance is non-negotiable
Slow software is broken software. I measure before I optimise - profiling, bottleneck identification, and targeted fixes. Not guesswork, engineering.
Write code for the next engineer
Clever code that only one person understands is a liability. I write for clarity - consistent patterns, meaningful abstractions, and documentation that actually helps.
Production-grade, always
Error handling, CI/CD integration, accessibility, observability - code I ship is code I'd maintain. Readable, testable, and built for the long run.
Experience
Software Engineer with 3+ years shipping production-scale applications using React, Next.js, TypeScript, and GraphQL. Strong on architecture, state management, API integration, and performance — across fintech, AI, and SaaS products.

Software Development Engineer
Implemented an AI-assisted workflow that compressed feature delivery from ~2 weeks to 2–3 days, cutting manual effort by ~80%. Solved Azure multi-tenant auth challenges, built scalable verification-workflow UIs for OnGrid, and delivered a Strapi-powered public site that jumped from Lighthouse 62 → 88 — enabling the marketing team to own content updates end-to-end. Won an internal hackathon (₹50,000 team award) for a solution with direct product impact.

Sprint to production
A small game, for the curious. Catch coffee and pizza to speed up the release; dodge bugs, crashes and strict QA.
