I help startups and product teams launch, improve, and scale web products with Ruby on Rails.

For more than 12 years, I have worked across the full product lifecycle: turning early ideas into production-ready MVPs, rescuing difficult Rails applications, integrating external services, and building reliable AI-powered workflows.

I lead StableLoop, a Rails & AI product engineering studio. My approach combines AI-assisted delivery with senior engineering judgment: every change is designed, reviewed, tested, and shipped with long-term maintainability in mind.

• Turn a validated idea into a clear technical roadmap
• Build the product in small, reviewable releases
• Implement authentication, core business workflows, integrations, and deployment
• Get a usable first version in front of real customers quickly

• Recover and document an unfamiliar codebase
• Upgrade Rails and reduce technical debt
• Improve performance, test coverage, security, and reliability
• Stabilize a product before a new launch, investment round, or team expansion

• LLM and OpenAI API integrations
• RAG and knowledge-based assistants
• Document extraction and structured data workflows
• AI agents and business-process automation
• Human approval, guardrails, observability, and cost control

• Docker-based environments
• CI/CD pipelines and automated testing
• Background jobs and third-party API integrations
• Linux deployment, monitoring, and production troubleshooting

• 12+ years building Ruby on Rails applications
• 25+ web products delivered
• 35+ Upwork engagements and 8,000+ billed hours
• Full-stack development plus hands-on deployment and systems experience
• Direct communication with the senior engineer doing the work
• AI-accelerated execution without sacrificing code review, testing, or ownership

1. Diagnose — understand the product, users, codebase, and business constraints.
2. Plan — define a practical roadmap made of small releases and clear specifications.
3. Build — implement each feature in a focused pull request with tests and documentation.
4. Verify — review quality, security, performance, and acceptance criteria.
5. Ship — merge through CI/CD and deploy with a repeatable process.

You keep full ownership of the code, infrastructure, and documentation. No lock-in.

If you need to launch an MVP, rescue an existing Rails product, or add production-ready AI features, I would be happy to discuss the project.
