Senior backend engineer available for contract, fractional, contract-to-hire, or full-time opportunities.
I have 30+ years of experience building and operating production systems across startups, SaaS, media, financial services, telecom, and public safety domains. I've worked in both early-stage and growth-stage companies and enjoy owning systems end-to-end, from architecture and implementation through deployment and operations.
For the past 13 years I've focused primarily on Ruby on Rails backend platforms, APIs, PostgreSQL, cloud infrastructure (AWS/GCP), and production reliability. My experience includes backend architecture, distributed systems, database performance tuning, cloud migrations, DevOps ownership, and operating customer-facing systems in production.
I enjoy helping teams solve scaling, reliability, modernization, and operational challenges. Particularly interested in backend, platform, infrastructure, and data-intensive systems, though I'm comfortable contributing across the stack when needed.
Available to help with Rails modernization, production reliability, cloud migrations, PostgreSQL performance tuning, backend platform development, and API-heavy applications.
