I design and build software the way engineered systems should be: clean layers, explicit contracts, real persistence and a pipeline that takes an idea to production without guesswork.

About me

Beyond the code

Backend-oriented software developer. I care as much about how a system is structured as about what it does: clean layers, explicit authorization, real persistence and a reliable pipeline from commit to production.

  • Backend-first: data models, business rules, APIs and authorization.
  • Not only web: the same engineering discipline applies to Android and JavaFX desktop.
  • Databases are design, not plumbing: relational and NoSQL, migrations and persistence.
  • Testing and automation are part of my normal workflow, not an afterthought.
