Description

Need a senior engineer who can own a product end-to-end — the React frontend, the Node/Python backend, and the data pipeline behind it? That's what I do.

Over 13+ years I've helped startups and product teams ship fast, reliable software: new features and MVPs, performance rescues, legacy modernization, API & integration work, and data/analytics pipelines.

A few things I've delivered: a Shopify/React admin used by 30,000+ stores; front-end render times cut from tens of seconds to milliseconds; ~20,000 lines of dead code removed via automation; and pipelines turning 1M+ records into analyzable graphs (PySpark, Elasticsearch, ML).

My stack: React, Next.js, TypeScript, Node.js, Python, PySpark, PostgreSQL, AWS, Docker. I write clean, maintainable code, review rigorously, and keep you updated throughout.

If that sounds like the missing piece on your project, let's talk.
