Minimal software for messy operational workflows.

I build production tools for retail, warehouse, and internal teams where the interface has to stay calm while the data underneath gets complicated.

Zetta Soft — Full-stack Developer

I designed and shipped the Match Barcode System end-to-end — Go, SQL, REST APIs, and React — owning requirements, schema, backend, frontend, and deployment. The system enforces scan-based verification before warehouse storage, reducing receiving mismatches to zero.

Also contribute features, bug fixes, and maintenance to an enterprise Inventory POS used across 70 retail branches with PostgreSQL-backed workflows, and shipped SCM and Production Order features for factory supply-chain workflows.

//about

Systems
clarity
production UI

Computer engineer turned full-stack developer, turning messy warehouse operations into validated, predictable software flows.

I build admin systems, operational tools, and product interfaces where edge cases matter more than decoration.

My work usually sits between frontend polish, backend rules, SQL data, and the people who need the workflow to be reliable every day.
