Backend engineer with more than 5 years building SaaS and marketplace products. I've worked on systems from day one to production scale, dealt with my share of legacy code, and learned to appreciate when infrastructure just quietly works.
I'm a software engineer with more than 5 years of experience building and scaling backend systems across SaaS and marketplace products. I've worked on things from day zero to tens of thousands of users, and inherited codebases that made me question everything I knew about software.
I gravitate toward hard problems — designing systems from scratch, making legacy code behave, optimizing the query that somehow takes 12 seconds, or convincing a distributed system to be consistent when it really doesn't want to be. I'm language-agnostic and tend to pick up new stacks as needed, but I do have opinions about keeping abstractions clean and infrastructure predictable.
SaaS products I've built end-to-end — backend, frontend, and infrastructure.
Multi-tenant point-of-sale for retail businesses.
A full POS SaaS — sales, inventory, purchase orders, shifts, expenses, stock opname, and per-branch daily cash reconciliation. Built for small retailers who outgrew spreadsheets but can't justify enterprise software.
Restaurant operations from QR-code ordering to the kitchen line.
Three apps in one product: an admin dashboard, a staff KDS + waiter map, and a QR-code customer PWA. Handles menus, orders, reservations, multi-branch reporting, and Midtrans payments — all offline-capable.
POS and operations for neighborhood laundry shops.
Order lifecycle from drop-off to pickup, customer history, pickup/delivery scheduling with WhatsApp notifications, expenses, and cash drawer reconciliation. Thermal receipt printing included.
