MOD-01 Architecture is decisions,
Architecture is decisions,
not diagrams.
For over a decade I have designed and built systems in the .NET ecosystem — from railway transport management, through banking and insurance integrations, to SaaS platforms. I specialise in situations where a system must survive contact with production: real load, real data, real users.
I run a software company where I own the entire technical side — from architecture, through CI/CD, to maintenance. What I write here comes from code that actually runs for clients, not from slides.

MOD-04 / INTERNSHIPS
Internships for pupils and students.
04years of the program — with more cohorts on the way
For four years I have run internships where pupils and students work on real projects — not throwaway exercises. Code review, working with a repository, a real delivery process and mentoring at every stage.
Recruitment and organisation of the internships happen through my company website.
