What I'm looking for

I’m looking for a backend-heavy role where I can own systems end-to-end - from architecture and API design to scaling and production reliability.

I’m interested in small, high-ownership teams where I can work closely with founders, contribute to product and technical decisions, and move from idea to production.

Senior Engineer and Engineering Leader with 9+ years building distributed, high-throughput backend systems at scale. Led architecture, GenAI initiatives, and cross-timezone engineering teams. Architected international logistics platforms (Warehousing1, Berlin) using Node.js, AWS, Kafka, and NestJS. Shipped production RAG pipelines on AWS Bedrock and OpenAI to automate internal processes. Equally comfortable owning technical roadmaps, running sprints, and writing code. Looking for remote Backend focused Senior IC roles or Engineering Lead roles.
