Open to work

Senior Full-Stack Engineer | Event-Driven Architecture, DDD, AI-Assisted Development

Full-stack engineer who loves building distributed systems and keeps doing it outside of work too. I specialize in event-driven architectures with Scala, Kotlin, and Akka, working with CQRS, Event Sourcing, and Domain-Driven Design in real production environments. On the frontend I build with React, TypeScript, and React Native. I hold a Master's degree with a thesis on DDD architecture because I believe great systems start with solid domain models. In my own time I maintain a multi-tenant portfolio platform on Payload CMS and I'm building a desktop game companion app with Rust and Tauri. I use AI-assisted tools in my daily workflow, and years of customer-facing consultancy work have made me just as comfortable talking to clients as writing code.
