Software Engineer III

Techzu Ichicode Pte. Ltd.

Jan 2026 — Present

Building SaaS ERP solutions for BDO Singapore on SAP Business One.

Promoted to 2IC of the project after probation; independently own the Procure-to-Pay and Inventory modules end to end, from requirements through deployment, while assisting on Order-to-Cash.
Built the Portable Data Terminal (PDT) React Native app from the ground up for warehouse barcode scanning — auth, inbound, outbound, operational and inventory-control workflows.
Own the code review process and manage deployments through Coolify, including database synchronisation and data patching to keep environments consistent.
Designed shared systems used right across the ERP — decimal rounding and approval-status-based posting — and contribute to modules outside my own.
