01 — about

Jr. Full Stack Developer based in Metro Manila. I build and ship production-ready apps across startups, enterprise systems, and personal products — from frontend UI to backend APIs and live deployment.

I care about clean systems that simplify workflows, whether that's e-commerce platforms, IoT builds, or AI-powered tools. End to end is my default: architecture, code, and delivery.

Inventory & Ordering System

B1G Corporation

Maintained and enhanced B1G Corporation's multi-tenant Inventory & Ordering System, which processes millions of pesos in monthly transactions — from stock allocation to agent orders, remittance, and finance approval. Key features we implemented: Consignment — consignee orders only appear in analytics after payment (not when placed), and each entry is clickable to show when that consignment order was created. AR (Accounts Receivable) — payment status is tracked per product line, not the whole order, so unpaid items stay visible until settled. FSN — products are classified as Fast, Slow, or Non-moving so the sales team can plan stock and promotions from real movement data.
