I help teams ship secure, production-ready web and mobile applications. My work spans fintech, SaaS, and high-growth startups — from banking integrations and energy-audit platforms to a genealogy product serving 5+ million individuals. Recent wins include an 80% API latency reduction and a fintech launched in just 3 months. I focus on the fundamentals: clean architecture, measurable performance, and shipping on time.
