I turn messy operations into systems that just run.
Bocaue, Bulacan — based full-stack developer who builds production operations systems, approval engines, and commission systems that replace manual work with something that scales. Comfortable owning a problem end to end: database design, backend, interface, and the edge cases nobody wants to think about.
Featured work
Led the build of four connected production apps — an internal operations system, an online shop, an agent portal, and a marketing site — all sharing one database and one central system behind the scenes.
Commission payouts across four channels were calculated by hand — slow, error-prone, and impossible to audit once money moved.
Built a commission engine covering four commission types, withholding tax, and pool splits — locking each record the moment an order completes so nothing can be changed after the fact.
Manual payout calculation eliminated entirely, with a flexible approval workflow now reused across cash advances and purchase orders.
Built a 34-module internal dashboard, all running on one shared system — spanning procurement, budgeting, HR, fleet, and approvals for the whole organization.
Department requests — supplies, vehicles, budget, cash advances, gate passes — ran through disconnected paper trails and spreadsheets. No shared audit history, and every team's approval process was reinvented from scratch.
Designed one workflow engine that handles every kind of approval — directors, department heads, AP/AR, treasury — with flexible multi-stage routing and full audit logging. Every module plugs into that same engine instead of building its own approval process from scratch.
34 modules now run on the same engine, from Request-to-Pay and expense budgeting to vehicle requisition and clearance — each new request type is just a new form, not a new approval system, with every step logged for a full audit trail.
Processed nationwide Tech4ED foot-traffic data into reporting templates, plus cleaning up existing code and manual testing across modules.
Trainings & certifications
Seven-course program covering the full UX process — empathizing with users, defining pain points, and prototyping and testing design solutions.
Five modules on applying generative AI tools responsibly to real work, including effective prompt writing.
Focused training on database normalization and SQL query functions.
Foundational Python programming course delivered with the OpenEDG Python Institute.
Background
Led a team of logistics officers across procurement, transport, and deployment for every club event — coordinating supply timelines, managing inventory, and planning event layouts end to end.
Let's build something that works.
Open to full-stack and product-engineering roles where I can own a problem from schema to shipped feature.
