Daniel Brai

I've built production backend systems across fintech, SaaS, and developer tooling, from payments infrastructure to AI-powered workflow automation. At Tribapay, I architect RESTful APIs and maintain Node.js microservices on AWS for savings, investment, and transaction aggregation used by thousands of business and consumer accounts. I also improved fraud detection, built multilingual AI-agent data storage, and developed a Python workflow engine with MCP and Stripe integration. For Flowscren, I built the backend platform for a design-inspiration SaaS with FastAPI, PostgreSQL, Celery, AWS, and Paystack subscription billing. I also architected CI/CD pipelines for Next.js, Vite/React, and FastAPI services across isolated staging and production environments. I've led cloud delivery at Beetle Ltd and built backend services at Cartolinks Solutions using Golang, TypeScript, Docker, FastAPI, AWS, PostgreSQL, and Azure. I’m especially interested in functional programming, including Elixir and Haskell.
