About Me
I am a Senior Software Engineering Leader with more than 20 years of experience designing, building, and scaling software systems across clinical, healthcare, legal, HR, and fintech environments. The work I find most meaningful is in healthcare and clinical technology, where strong software can directly support patients, clinicians, researchers, and care teams.
My background spans full-stack architecture, backend APIs, data platforms, frontend applications, infrastructure, and system integration. I am strongest where hands-on engineering, systems thinking, and technical leadership come together — translating complex requirements into clean architecture, practical execution, and durable products.
I also bring a research-oriented mindset shaped by doctoral work in biomedical signal processing and computational analysis, which continues to influence how I approach data-rich systems and complex technical problems. More recently, I have been expanding my work with AI-enabled applications, AI-assisted development, and modern platform design.
