Where the 9+ years went
December 2016 to May 2017 at Phoenix Media, building an e-commerce platform and a lead management system in PHP. September 2017 to May 2025 at Instant Systems Inc, embedded with its portfolio companies — Ceekr, SYNQY Corporation, Humanize and Clove Dental. May 2025 to now at India Today Group as a Senior Software Engineer on MERN and Generative AI.
- News media — election data pipelines, editorial AI tooling, video CMS
- Healthtech — a patient relationship system in use across 500+ dental clinics
- Adtech and retail media — analytics dashboards and serverless reporting at SYNQY
- Real-time — WebRTC video and audio meetings with screen sharing at Humanize
What I actually build
Full-stack systems in JavaScript and TypeScript: React and Next.js on the front, Node.js, Express and NestJS behind, MongoDB or MySQL underneath, Redis in front of the hot paths, and AWS around all of it. Where a feature needs a language change I use it — the TrendMeToday ingestion pipeline is Python and FastAPI because that is what the job wanted.
- Real-time delivery — Redis pub/sub, server-sent events, WebSocket, CDN-aware caching
- Generative AI — OpenAI and LangChain, RAG on MongoDB Atlas Vector Search, voice synthesis
- Cloud — AWS Solutions Architect Associate coursework, Docker, CI/CD, serverless
- SEO engineering — programmatic pages, JSON-LD, Core Web Vitals as a build budget
Working with a software developer based in India
I work from New Delhi on IST (UTC+5:30) and take on-site work across Delhi NCR or fully remote engagements worldwide. For Indian companies that means an engineer in the same timezone who can be in the room; for overseas teams it means a full overlap with Europe and a partial one with the US, plus written handovers so nothing waits a day for a reply.
