I've built payment, credit ledger, wallet, and enterprise backend systems across NiteShift Systems, ETTA Solutions, and Ahaz Software Solutions. At NiteShift Systems, I re-architected a frontend-authoritative credit flow into a backend-controlled ledger and synchronization model, eliminating all credit-related support tickets after release. I also orchestrated Stripe checkout, webhooks, subscriptions, purchase ownership, and content access for digital music products. At ETTA Solutions, I moved manual tender management and internal transfer processes into structured operational workflows, delivered an ERCA-compliant document signature and verification service, and integrated Mastercard payments, digital wallets, SMS notifications, and legacy CNET data. I've also automated biometric attendance ingestion and payroll workflows, built HRMS APIs, and developed projects including a FastAPI runtime-flow reconstruction platform and a Spring Boot control plane for self-hosted Odoo deployments.
