Rongon Bairagee

I’m a Results-driven Senior Full-Stack Software Developer with over 6 years of experience architecting, developing, and deploying scalable web applications and SaaS platforms. I focus on turning complex business logic into clean, maintainable code—while keeping security, performance, and server optimization at the center of every build.

Since March 2024, I’ve been leading and mentoring a cross-functional team, enforcing clean code standards through code reviews and technical guidance. I architect and develop high-performance multi-tenant SaaS applications, custom LMS programs, and B2B multi-vendor e-commerce platforms, including highly secure HR and Finance Management ERP modules with strict data isolation and validation.

I also optimize MySQL for high-traffic environments—improving schema and query performance to significantly reduce API response latency. On the infrastructure side, I configure and maintain Linux production servers using Nginx, deploying applications securely with automated backups and delivering 99.9% uptime.

Before that, I built RMG (Ready-Made Garment) production automation modules at Barcode-tech Automation Ltd., including real-time production tracking, inventory management, production planning, and merchandising. I engineered ETL pipelines from legacy ERP databases into centralized dashboards, built responsive frontend portals using Lumen/vanilla JavaScript/jQuery/Bootstrap, and resolved production bottlenecks to keep systems running smoothly.
