What I'm looking for

I seek roles building AI-native platforms or scalable web services where I can lead technical design, improve developer experience, and ship reliable, production systems.

I am a senior software engineer specializing in AI-native developer platforms and scalable web services. I design and implement production-ready systems that bridge specification-driven workflows with agentic code execution.

At Thoughtworks I led the Specification + MCP workflow for an AI-native SDLC platform and provided technical leadership to a team of four engineers, improving code quality and team velocity through pair programming and design reviews.

I have driven high-impact product work including end-to-end UPI and NetBanking payments handling significant volumes, migration from a legacy monolith to Medusa.js saving substantial licensing cost, and automation tooling that cut reporting turnaround from days to minutes.

I build AI-integrated applications and developer tooling using modern stacks (Next.js, Vercel AI SDK, LangGraph, Python, TypeScript) and infrastructure (AWS, Docker, Terraform), focusing on reliability, observability and developer experience.
