From hardware benches in the Philippines to cloud systems in Costa Rica.

I'm a software engineer and full stack developer based in Heredia, Costa Rica, with roots in the Philippines. My work combines polished frontend development, Node.js and Express APIs, automation scripts, third-party integrations, CMS platforms, CRM/ERP workflows, and cloud deployment.

Before focusing on software, I spent years hands-on with hardware, networking, and computer service across the Philippines. That foundation means I understand systems from the user interface down to operations, support, and the real-world business workflow they have to serve.

04 Projects

Case studies — the problem, the build, the result.

Client systems can't always be public, so each case walks through the problem, the build, and the measurable result — full walkthroughs available on request.

operations-erp-saas market categories
ERP / SaaS 2024 — 2025 Client Delivery

Operations ERP — Multi-tenant SaaS

The problem. A growing operations team was juggling spreadsheets for inventory, invoicing, and staff permissions across multiple branches — with no single source of truth.

The result. A multi-tenant, ERP-style SaaS with role-based access, live inventory, invoicing, and branch-level reporting. One login replaced five spreadsheets.

  • 5 spreadsheets retired
  • 3 branches
  • Live reporting

ERP Integration 2023 — 2024 Client Delivery

E-commerce → NetSuite Integration

The problem. Every online order was re-keyed into NetSuite by hand. Stock counts drifted between the storefront and the ERP, so the shop oversold items the warehouse no longer had.

The result. A two-way integration that pushes orders, customers, and fulfilments into NetSuite and pulls inventory and pricing back to the storefront — with retry handling and an error queue so nothing is lost silently.

  • Zero manual re-keying
  • Two-way sync
  • Retry + error queue
  • NetSuite
  • REST API
  • Webhooks
  • Order Sync
  • Inventory

Automation 2021 — 2023 Client Delivery

WooCommerce Store Automation

The problem. Store operators were spending hours every week manually updating products, stock levels, and order paperwork.

The result. Automated product updates, stock rules, order workflows, and reporting pipelines — returning roughly eight hours per week to the operations team.

  • 8 hrs/week saved
  • Auto stock rules
  • Order pipelines
  • WooCommerce
  • PHP
  • Automation
  • Reporting

CRM Integration System

The problem. Leads and customer data lived in four disconnected systems, so routing and visibility depended on manual copy-paste.

The result. Lead routing, CRM sync, internal dashboards, and role management that keep four business systems in step automatically.

  • 4 systems synced
  • Automated routing
  • Role-based access
  • CRM
  • REST API
  • Dashboards
  • Role Management

Google Drive / Zoho API Sync

The problem. Documents and records had to exist in both Google Drive and Zoho, and keeping them aligned by hand didn't scale past a few hundred files.

The result. Two-way document and record sync with retry logic, audit trails, and scheduled background jobs — currently tracking 12,000+ records.

  • 12k records
  • Two-way sync
  • Retry + audit
  • Google APIs
  • Zoho
  • Cron Jobs
  • Audit Trails
