Software EngineerVaud, Switzerland
Euan Cowie
I build whole systems: the app, the services, the data, and the cluster they run on.
Ten years building production systems end to end — React and TypeScript at one end, Kubernetes, Postgres and CUDA at the other — across private banking, genomics, maritime safety and AI tooling. A GWAS kernel that runs half-million-sample studies on one consumer GPU. A hybrid AWS and on-premise platform behind GPU inference on oil rigs and wind farms. On my own time, a live iOS product with a Neo4j food graph doing RAG behind it. Five of the ten years remote.
Open to engineering roles — remote, or hybrid in French-speaking Switzerland.
Selected work
All case studies →Founder and sole engineer
A React Native app, a Convex backend, a Neo4j food graph with vector search behind a Java service, and the Kubernetes cluster it runs on — built and operated by one person, live on TestFlight.
TypeScript / React Native / Expo / Convex / Neo4j / Java / Spring Boot
Heilsa2025—PresentSoftware Engineer
Built and ran the platform behind a GPU inference product — AWS and on-premise, Terraform, Kubernetes, CI/CD — and made it self-service for 20+ engineers. It deployed to oil rigs, wind farms and cruise ships.
AWS / Terraform / iPXE / Kubernetes / NVIDIA Jetson / WebRTC
Zelim2023—2025Software Engineer
React portals over a Rust/C++/gRPC control plane, a monolith split into services, and self-hosted observability across an eight-GPU box — above a CUDA kernel that runs 500,000-sample studies on one consumer card.
CUDA / C++ / Rust / React / gRPC / Distributed systems
Omecu2021—2023Software Engineer — Module Lead
Java and Spring microservices on Kubernetes for Tier-1 private banks: high-volume transaction processing, EU tax APIs, and the cross-functional team that delivered them.
Java / Spring / Kubernetes / Microservices / REST APIs / Regulatory reporting

Open to interesting problems
If you are building something that has to be fast, or cheap, or has to keep running somewhere nobody can reach it, I would like to hear about it. Email is the surest way to reach me; LinkedIn works too if that is your usual route.
