At SITERP, I build and maintain a 30-module ERP used by 10+ SME clients. I work across the React front end, Node.js/Express services, and PostgreSQL, taking features through production releases.
I automate recurring business workflows with REST APIs, webhooks, scheduled jobs, and email notifications. I also implement authentication and per-module permissions, and validate releases with smoke and CRUD tests.
At SITEK AGENCY, I deliver React, Node.js, and PostgreSQL applications and integrations for SME clients, from requirements through deployment and handover. Previously, at NEDJM FROID, I built a bank reconciliation tool that cut manual processing by about 50% and improved the performance of 3+ financial applications by 25%.
