Building reliable, testable, production-grade web systems
I'm a senior full-stack engineer with deep experience in Ruby on Rails and React, focused on building systems that are clean, tested, and ready for production. I care about writing code that teams can maintain and build on — not just code that works today.
I specialize in:
- Designing scalable REST APIs and backend architectures
- Modern frontends — React, Next.js, Tailwind CSS, responsive and accessible UI
- Legacy modernization — Rails upgrades, dependency resolution, migration planning
- Test automation — RSpec, Cypress, Postman/Newman, CI/CD integration
- DevOps & deployment — Docker, Capistrano, CI/CD pipelines, Heroku, AWS S3
- Observability & reliability — background jobs, query optimization, logging
- Technical leadership — design docs, code reviews, mentoring

Testing & DevOps
I'm open to senior/full-stack engineer roles, tech lead positions, and consulting on Rails architecture or API design. I enjoy working on healthcare and fintech platforms, high-availability APIs, and complex legacy migrations.
