Claude Code first — vibe coding, backed by engineering discipline.
More and more of my code is written together with Claude Code. I drive the architecture, the domain and the review; the agent does the heavy lifting; tests and code review keep it production-grade.

03 / Approach
Architecture should make change easier, not block it.
Backend, frontend, system integration, architecture design and delivery — end to end.
Event-driven, hexagonal (Ports & Adapters), DDD, CQRS, Clean Architecture.
Remotely, in Scrum and Kanban teams.
Oracle OCA (Java SE) and OCS (ADF 11g/12c, SOA, BI, DW). MSc in Computer Science, Lodz University of Technology.
devstyle.pl programmes: Architekt Jutra, Archetypy oprogramowania, Domain Drivers, Legacy Fighter, DNA, Smart Testing.
AI-first delivery: I steer, Claude Code builds, and architecture, tests and review keep quality high — faster prototyping, debugging and API documentation.
