About Me

A software engineer who understands business, not just code.

I build and lead backend & full-stack systems for mining and fintech companies — from internal ERPs and Single Sign-On to real-time data warehouses and IoT-based Fleet Management Systems. I currently serve as Supervisor Digital Product Lead, responsible for the product roadmap, budgeting, and a 6-person engineering team.
