Acerca de este Servicio
Need a reliable Node.js developer who delivers clean, scalable backend code on time, every time?
WHAT I BUILD:
REST APIs (Node.js, Express, Fastify)
Backend architecture for SaaS platforms & dashboards
Database design (MongoDB, PostgreSQL, MySQL)
Third-party integrations: Stripe, Shopify, Twilio, Slack, OpenAI
AI-powered backend features & agent integrations
Authentication, authorization & role-based access
CI/CD setup & deployment
WHY WORK WITH ME:
- Former Technical Lead I write code the way senior teams expect it: clean, documented, tested
- Direct experience integrating payment gateways, AI APIs, and third-party services into production systems
- Clear communication you'll always know project status, no chasing for updates
- I under-promise on timelines and deliver ahead of schedule
Whether you need a simple API built from scratch, an existing backend fixed and optimized, or a full SaaS backend architected from the ground up, I'll scope it clearly before we start so there are no surprises.
Message me with your project details I usually reply within a few hours.
