Johore, Malaysia
Full-stack engineer and technical lead with 9+ years of experience building scalable, business-critical platforms across ERP, IoT telemetry, and payments. At Happy Ice, I architected and built an ERP + IoT ecosystem from scratch supporting operations in Singapore, Malaysia, and Indonesia. The platform powers 400+ vending machines and processes 100,000+ transactions per month, with strong focus on reliability, concurrency safety, and operational automation. Key areas I work on: • Backend platform architecture (Laravel, REST APIs) • Real-time telemetry & fault alerting (MQTT; power failure & temperature anomaly alerts) • QR payments integration (Omise/Opn, Midtrans) and transaction-safe flows • Queue-driven background processing for long-running workflows • Performance optimization (N+1 prevention, indexing) • RBAC access-layer design for internal teams and customer portals • Cross-team integration with Android/embedded vending machine software I’m open to hybrid-friendly opportunities in Singapore from April 2026. References and selected project demonstrations are available upon request (subject to confidentiality).
