For 7+ years I've been designing scalable backend systems and microservices architectures in the .NET ecosystem. From enterprise ERP platforms to logistics, from SAP integrations to e-commerce marketplaces — I've built the systems where the load actually lands, and led the teams that built them.
Moving from a monolith to service-based architecture, drawing domain boundaries, inter-service messaging. I use CQRS and Clean Architecture not to follow the book, but so the team can make changes with confidence.
Making systems that work — but nobody dares touch — safe to move, without stopping production. I ran the .NET 8 migration at Sendeo and the legacy → CQRS transition at Amaris. Technical debt isn't a slide in a deck; it's work that goes into the sprint.
I built the SAP and ADIS (MobilPark) integrations at Koton, and the Trendyol / N11 / Hepsiburada marketplace integrations at Sendeo. In enterprise integration the real work isn't the code — it's the failure and reconciliation scenarios.
At Sendeo I cut API response times by over 30% through caching strategies and code optimization; at Extratik we brought them under 500 ms. Measurement infrastructure first, optimization second — the reverse is guesswork.
I've led cross-functional teams of up to 8. Architecture review, establishing PR and code review processes, development standards, sprint planning and technical roadmaps — what speeds a team up is process, not pressure.
At Tatko I define the architecture of the ERP platform; at Extratik I designed a BPM system that automated internal workflows. Plus 2.5 years of domain depth in pre-accounting and e-invoicing from SahaTek.
Experience
Across logistics, retail, ERP and fintech-adjacent pre-accounting — from developer to technical lead.

How I work
I don't like surprises. At every stage you'll know where we are and what the next step is.
I get to know the existing system, the constraints and the actual business goal. More often than not, the problem stated isn't the problem that needs solving.
I lay out the alternatives, their costs and their consequences, and I make a recommendation. You make the call — but not blindly.
Small, reviewable increments shipped regularly through CI/CD, with working software at every step. No "I'll show you at the end."
Documentation, the reasoning behind architectural decisions, and mentorship for the team. The system has to stay touchable after I'm gone.
Contact
Got a new system to build, a legacy application that needs migrating, or an architectural decision you'd like a second opinion on? A short call usually gets further than weeks of discussion. First call is free.
