Bengaluru, India - 12:55 am local time
I’m a backend developer specializing in Node.js, TypeScript, Python, Cloudflare Workers, PostgreSQL, AWS Lambda, REST APIs, GraphQL, and Stripe integrations. I help SaaS teams fix slow APIs, unreliable payment flows, broken integrations, and backend systems that are starting to fail under real traffic.

Recent results include scaling a European SaaS backend to 4M+ API requests/day and €1.5M/month in payments, reducing response times from 350ms to under 100ms with zero downtime.

That’s the kind of problem I’m best at, APIs that are slow, payment systems that are flaky, infrastructure that wasn’t built for the load it’s now getting.
Recent work on Upwork
• HIPAA-compliant healthcare backend
• AI chatbot with a RAG pipeline (OpenAI, LangChain)
• Stripe integrations across several SaaS products, no failed transactions
• High-volume edge APIs on Cloudflare Workers

How I work: I scope the problem before writing code, send updates twice a week, and own the outcome instead of just closing tickets. Most clients here have either extended or come back with new work.
If something in your backend is broken, slow, or about to break at scale, tell me what’s happening and I’ll tell you how I’d fix it.
