Lukas Campos

Software Engineer · Berlin · Remote-first

I build backend systems that handle real-time data at scale.

20+ years coding, 10+ years shipping trading platforms and streaming infrastructure for banks, logistics, and energy companies across Europe.

I also build products. I ran a consultancy for a few years, but preferred going deep on fewer projects. So I went solo - one long-term client, lean operations, and room to build my own products on the side.

Work

Currently: Energy trading systems for a European energy company since 2022. Built a portfolio valuation and positions platform (Angular, TypeScript, AWS serverless), modernized a core Java system with a Kafka integration, and now own its path to production on new infrastructure.
