Sobre mim
Backend developer specializing in scalable APIs, database architecture, and secure web applications. I build REST APIs, backend systems, authentication, payment gateways, AI integrations, and automation workflows using Node.js, Express.js, Supabase, Firebase, PostgreSQL, MongoDB, AWS, and SQL. I integrate Stripe, webhooks, third-party APIs, CRMs, and cloud services while optimizing performance, security, and scalability for SaaS, AI, eCommerce, and custom web applications. I also develop serverless functions, API debugging, cloud deployment, database optimization, and custom backend solutions.
