Full Stack Developer · APIs & scalable back-ends · 5+ yrs · Ahmedabad, India

Hi, I'm Satish — I build fast, scalableback-ends & APIs.

Full Stack Developer with 5+ years — most of it deep in the server layer, architecting and scaling RESTful APIs and microservices in Node.js and Express, backed by MongoDB, MySQL, and Redis caching. I design reliable, low-latency back-ends (sub-200ms responses, 99.9% uptime) for high-traffic platforms with 100K+ users, then pair them with clean React and Next.js front-ends to ship features end-to-end.
