What I'm looking for

I'm looking to own backend architecture, real-time data pipelines, and operationally reliable infrastructure for production systems.

At GoGroup, I architect backend systems and AWS infrastructure supporting 1,500+ active accounts across Germany, the Netherlands, Spain, and New Zealand. I built a real-time multi-vendor ranking engine that returns results in 200–400ms and an event-driven ingestion pipeline that reduced data-reliability incidents by 35%.

Previously at Altizon, I shipped Rails APIs and React features for an industrial IoT analytics platform, built a document management system on AWS, and delivered ETL and background-job pipelines that reduced processing time by about 25%.

I also build independent infrastructure projects, including SignalSnitch, a kernel-level network observability engine, and TotallyHuman, resilient TLS-layer web automation infrastructure. I enjoy owning systems end to end—from architecture and data pipelines to operational reliability.
