What I'm looking for

I’m looking for a senior role where I can own architecture and delivery end-to-end, build secure scalable systems (WMS/POS/procurement/HRIS), and work with remote autonomy on real-time, offline-capable, high-impact products.

I’m a result-driven Senior Full Stack Developer with 9+ years of experience architecting, building, and deploying scalable web and cross-platform mobile systems. I specialize in enterprise Procurement Management, Warehouse Management (WMS), Point of Sale (POS), and HRIS—delivering end-to-end solutions from design to production, especially in remote, high-autonomy environments.

In recent roles, I’ve led enterprise WMS initiatives that digitize field operations with reliable offline execution, distributed synchronization, and real-time reporting to improve inventory accuracy. I also modernized POS for consistent multi-channel data synchronization, built secure backend services with Laravel and Node.js/TypeScript, and improved HR workflows through automation—while maintaining stable releases and strong quality practices, including an 85% reduction in operational errors via automated testing.
