About me
I'm a backend engineer with 5+ years of production experience. I'm currently an SDE 2 at KPN Farm Fresh, where I own the promotion, price and customer services in a platform of 100+ microservices written in Go and Node.js (Fastify).
Before that I spent two and a half years at SenseHawk, building an organization-wide document management system, multi-stage approval workflows with role-based access control, and a FastAPI integrations platform.
I like owning a service end to end: API design, data modeling, and being the one who fixes it when it breaks in production. I got my start teaching, mentoring MERN-stack students at Masai School.

Let's talk
I'm open to backend roles, remote or in Bengaluru, and always happy to talk about distributed systems, Go or Node.js. Email is the fastest way to reach me, or use the form.
