I build reliable software systems that solve complex, real-world problems — from medical imaging platforms to custom automation tools that save businesses time and reduce operational overhead. I’m a senior software engineer with a strong background in backend, systems, and integrations, comfortable working across C, C++, C#, Java, JavaScript, and SQL, and equally comfortable owning a problem from architecture to production. In recent years, I’ve: - Reduced administrative workload by 30–40% through workflow automation - Increased business visibility by ~80% by delivering custom web platforms - Delivered 5× more features and fixes on legacy systems by untangling complex codebases - Improved production stability by eliminating years of accumulated technical debt A large part of my experience is in medical software, where correctness and reliability are non-negotiable. I’ve built and maintained systems integrating with real medical equipment using HL7, DICOM, MWL, MPPS, and PACS, including debugging live data streams without documentation and delivering standards-compliant services in production. I’ve also worked on platforms serving 180,000+ users, designed scalable backend architectures, optimized databases, and led small teams to deliver custom CRMs and internal tools from scratch. Today, I work both as: - an independent software engineer through keepcoding.tech, helping businesses build and maintain custom software, and - a hands-on engineer who enjoys joining teams to solve hard technical problems and ship production-ready systems. I value clarity, maintainability, and impact over buzzwords, and I enjoy working close to the problem space — whether that means low-level C code, backend services, or deployment and infrastructure.
