Full-stack and integration developer with 2 years of experience building telecom systems with React, Node.js/TypeScript, PHP and SQL.
At a telecom company with 200K+ subscribers, I built a new customer platform end-to-end, up to v1.0: React micro-frontends, a documented REST API, payments with 3-D Secure, a CRM integration and an event-driven Node.js service, with Docker, CI/CD and automated tests. I then moved to integrations and automation: connecting the CRM with external partners (open banking, telephony, messaging) through REST APIs, webhooks and n8n, and replacing manual work with more than 20 automations.
