André de Souza

Senior Software Engineer specializing in backend development, APIs, integrations, debugging, and performance optimization.

I can help with both small, quick tasks and larger projects, including bug fixes, API development and integration, database and SQL work, backend features, automated testing, Docker and deployment issues, data processing, and troubleshooting existing applications.

My main stack is Elixir/Phoenix and PostgreSQL, with professional experience across JavaScript/Node.js, PHP, React, Docker, AWS, CI/CD, and distributed systems. I have worked on financial platforms, SaaS products, and developer infrastructure, including Supabase/Logflare.

Available for one-time fixes, short projects, and ongoing development work.
