I have spent more than 5000 days of my life pursuing the zen of creative software development. I pride myself on continuing the values that I learned in the early days of the software industry, the 1990s. My career has spanned decades in many different industries, but I have worked almost exclusively in software and my fallback, professional cooking. When I'm not working, I spend my time hiking, gardening, crafting and making retro video games under the name Lost Astronaut Studios.

I’m a Staff-level backend engineer with extensive experience building and owning business-critical systems across fintech, payments, sensitive-data management, and global digital commerce. I can help you with complex backend problems where the answer isn’t obvious — reviewing architecture and system designs, debugging difficult production issues, improving existing systems, reviewing code, and working through scalability, reliability, concurrency, and maintainability challenges. My primary stack is Java and Spring, with deep experience in microservices and distributed systems. I’m particularly useful when you need more than a quick coding answer: you want someone to understand the problem, challenge assumptions, discuss trade-offs, and help you arrive at a solution you can confidently implement. I also mentor experienced engineers preparing for Senior, Lead, or Staff-level responsibilities, including system design, technical decision-making, and code/design reviews.
