I am a software engineer with 20 years of experience. My career is defined by a fascination with complex systems, ranging from a high-performance desktop framework and a business intelligence application to high-stakes fraud mitigation.
Throughout my path from engineer to VP of Engineering leading teams of up to 100, my focus has remained constant: driving organizational scale with technical excellence and thoughtful craftsmanship rather than title prestige.
Beyond engineering, I document my journey through technical blog posts and occasionally speak at developer events.
