Recruiter Snapshot

I help teams move complex platforms without losing the plot: clarify boundaries, prove risky paths early and leave behind systems that are easier to operate.

• Current NATO/EU SECRET-level security clearance and previous NATO Headquarters experience in high-trust operational environments.
• Master of Science in Information Technology and Bachelor of Science in Computer Science.
• Current railway assignment combines primary React/TypeScript frontend ownership, Web API contract design, backend support, Azure Event Hubs integration adapter delivery, GIS workflow integration, migration planning and architecture coordination.
• Repeated delivery in regulated and operationally sensitive domains: NATO, financial services, insurance, industrial engineering and railway systems.
• Comfortable owning complete delivery slices when needed: clarifying requirements, defining contracts, implementing UI/API/integration pieces, testing and documenting the result.
• Strong record in modernization, performance recovery, data migration, event-driven systems, secure identity flows and maintainable frontend architecture.

Engineering Principles

The way I prefer to make architecture useful: clear boundaries, testable contracts, secure defaults and systems teams can maintain.

Selected Case Studies

Selected examples that show architecture judgment, delivery ownership and backend/API direction without exposing client-confidential details.

Professional Experience

Enterprise software delivery, integration architecture, cloud-enabled systems and hands-on engineering.
