Senior Software Engineer | Full Stack Ruby on Rails

About me

Senior Full-Stack Ruby on Rails Engineer, having 6+ years of experience specializing in scaling and optimizing mission-critical SaaS platforms across FinTech, HealthTech, and Enterprise SaaS. I architect and refactor complex systems—from multi-tenant commission engines (Concert Finance) to large-scale legacy codebase migrations (YourParsley).

I drive measurable results in performance and stability: achieving a 60% reduction in page load times, implementing PCI compliance, and cutting infrastructure costs by 30% (Heroku to AWS migration).

Tech Stack: Full-Stack Ruby on Rails (4-7), React/TypeScript, Python/FastAPI, PostgreSQL/Elasticsearch, AWS (Terraform, Lambda), and Microservices. Expert in performance tuning, TDD/BDD, and leading technical strategy.
