What I'm looking for

I seek senior backend or architecture roles where I can own scalable, secure systems, mentor engineers, take DevOps responsibilities, and shape technical direction in collaborative, growth-focused teams.

I am a senior technical architect and staff engineer with professional software development experience since 1999, focused primarily on backend systems, scalability, and high availability.

I have authored or co-authored virtually all business-critical components at startups and established vendors, including billing, inventory management, APIs, integrations, search, and data import/export systems.

I bring hands-on experience across the full lifecycle: design, development, incident response, selected DevOps duties, performance tuning, and hiring/screening engineering candidates.

I am a long-time Linux enthusiast, active community member (Java User Group), and pragmatic engineer who values reliable, secure, and maintainable systems that serve global customers.
