What I'm looking for

I seek a Full Stack Rails Engineer role in a collaborative fintech or healthcare-focused team to lead API performance, secure CI/CD pipelines, and architect scalable, reliable systems while mentoring engineers.

I am a senior full-stack developer with 6+ years building fintech and healthcare applications using Ruby on Rails. I specialize in API design, backend performance optimization, and CI/CD automation.

I led projects that reduced load time by 40%, cut technical debt by 27%, and increased transaction efficiency by designing a payment processing system. I improved test coverage with RSpec and Minutest, implemented Sidekiq background jobs, and built RESTful and GraphQL APIs to enable real-time synchronization.

I secure sensitive data using JWT, OAuth 2.0, AES encryption, and RBAC, and I streamline deployments with Docker, Kubernetes, and GitHub Actions to reduce downtime. I am seeking a Full Stack Rails Engineer role where I can drive architecture decisions, mentor teammates, and deliver measurable performance gains.
