👋 Hi, I'm Ana Gomes

Backend-focused Full-Stack Engineer specialized in scalable SaaS systems, backend architecture, and AI-driven infrastructure.

I design and build production-grade web platforms using Ruby on Rails, PostgreSQL, and cloud infrastructure — with a strong emphasis on performance, system boundaries, and long-term maintainability.

🧠 Engineering Focus

  • Scalable backend architecture (multi-tenant systems, RBAC, secure data isolation)
  • PostgreSQL performance & query optimization
  • API design & versioning strategies
  • Background job processing & async workflows (Sidekiq patterns)
  • Caching strategies (Redis, HTTP caching)
  • AI systems optimization & cost-efficient LLM integrations
  • Observability & production reliability

I prioritize architectural clarity over quick fixes and build systems that balance product velocity with technical sustainability.

🚀 Selected Work

AI-Integrated SaaS Platform (Ongoing)

Building a canvas-based SaaS platform with real-time AI workflows.

Key engineering contributions:

  • Designed secure multi-tenant backend architecture with role hierarchies
  • Reduced API calls by 90–95% through local-first persistence & caching strategies
  • Engineered AI token optimization layer cutting infrastructure costs by 70–85%
  • Structured PostgreSQL data models for scalability and performance
  • Implemented unified AI orchestration layer (OpenAI, Claude, Gemini, Whisper)
  • Improved observability with structured logging and error monitoring

Core stack: Ruby on Rails · PostgreSQL · Redis · AWS · Docker · React · TypeScript

Freelance Systems Development
