I'm a fullstack engineer with experience building scalable web applications and distributed systems. My background spans both enterprise environments and solo-founded products, giving me a mix of clean architecture discipline and fast, iterative delivery. I thrive in startup environments where I can wear multiple hats, from technical architecture to product strategy, and contribute across the entire product lifecycle. At Continental Automotive, I led the turnaround of a delayed global ASP.NET Core tool by refactoring a monolithic codebase, implementing role-based access control, and improving performance with targeted SQL optimizations. At Mercedes-Benz (via Alten), I built automated C# test suites for in-vehicle telematics, reducing pre-production failure rates by debugging integrations across backend APIs and embedded systems. As a solo founder, I’ve shipped real-world products from concept to production, and I’m continually expanding my expertise in distributed systems with a focus on event-driven architectures and resilient product design. I’m comfortable navigating ambiguity, making technical trade-offs under resource constraints, and adapting quickly to changing business requirements.
