What I'm looking for

I'm open to remote or relocation opportunities where I can architect and deliver scalable ERP, SaaS, AI-powered automation, and real-time enterprise platforms.

I've delivered large-scale ERP, SaaS, and enterprise platforms at Echo Media and Cosmo Solutions, including a 22-module ERP for multi-branch operations and an offline-first POS system with real-time synchronization.

I build full-stack, cloud-hosted systems using React, Node.js, Laravel, PostgreSQL, and Supabase, with microservices-ready architecture, AI automation, secure RBAC, and real-time workflows. I've also delivered multi-tenant SaaS products and enterprise platforms for international clients while mentoring engineering teams.
