I help growing companies ship reliable, scalable software by designing backend systems that handle complexity without breaking under pressure. I specialize in building clean, maintainable APIs and event-driven architectures using CQRS patterns — turning messy business logic into systems that are easy to reason about, extend, and operate in the cloud. I actively integrate AI-assisted and agentic engineering workflows into my practice — building systems where AI doesn't just assist, but acts.
