Profile
Product-minded, architecture-heavy, still close to the code.
Software engineer and software architect with deep experience in fintech, backend platforms, event streaming, technical leadership, and team development. I have moved between startup speed and enterprise-scale systems, always with a bias toward clear design, tests that prove value, and technical decisions that keep delivery moving.
I care about the engineering culture around the system as much as the system itself: pair programming, mentoring, recruitment, career guidance, and building teams that can reason well under pressure.
Hands-on architecture
Designed and scaled systems around event streaming, modularisation, AI engineering, agentic systems, AWS, and legacy modernization.
Craft and teams
Built engineering communities around TDD, DDD, clean code, pair programming, mentoring, recruitment, and practical agile delivery.
