I’m a Senior Backend Engineer with 6+ years of production experience building scalable Node.js systems, and I’ve owned backend architecture end to end—building an entire ERP system from zero to live production. As a Team Lead, I led a backend team of 4 engineers across Inventory, Manufacturing, and Point of Sale modules while shipping features that directly impacted real users and daily operations.

My strongest differentiator is production depth plus ERP domain expertise: I designed multi-location stock management with FIFO/LIFO/AVERAGE costing, eliminated overselling for concurrent POS billing using PostgreSQL pessimistic locking, and built an offline sync engine for POS terminals with zero data loss via local transaction queue and reconciliation. I also optimized critical PostgreSQL queries using EXPLAIN ANALYZE and composite indexes, and delivered manufacturing workflow modules like BOM and production variance tracking. I’m seeking a remote Senior Backend or Full Stack role where this combination of reliability and domain knowledge drives impact from day one.
