01 About
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.
Responsive websites, dashboards, portals, and full stack app interfaces — researched, designed, and shipped.
Express services, status endpoints, authenticated routes, integrations, and documentation.
Workflow automation with cloud jobs, webhooks, scripts, and business system sync.
CRM/ERP customization, integrations, reporting, permissions, and operational tooling for lead and workflow management.
Clean, message-focused interface design using modern product flows, component systems, and visual polish.
Motion graphics, product explainers, animated assets, and launch material that make ideas memorable.
User-friendly iOS and Android app experiences, with native mobile skills advancing through degree studies.
Performance passes, metadata, visibility cleanup, and practical strategies for organic traffic.
02 Skills
Grouped by where they live in the stack — from interface work to the cloud jobs running behind it.
03 Experience
My path blends hands-on technical support, frontend work, backend integrations, cloud APIs, and automation.
Managed computer service work across the Philippines — maintenance, repairs, networking, and hands-on troubleshooting for real customers.
Studied ICT, PC assembly, software troubleshooting, and computer system servicing through school and technical coursework.
Built a new professional base in Costa Rica and expanded from repair work into web development, operations systems, and client delivery.
Created user-facing pages with HTML, CSS, JavaScript, WordPress, and UI implementation while growing collaboration and delivery skills.
Expanded into backend workflows, API integrations, WooCommerce automation, CRM systems, and production support.
Started a second degree in software engineering — deepening formal foundations in architecture, mobile development, and engineering practice alongside client work.
Focused on Express.js APIs, cloud systems, app development, automation, and polished developer-focused products.
04 Projects
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.
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.
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.
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.
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.
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.
These are the highlights — a top slice of 80+ delivered projects spanning ERP, e-commerce, automation, CMS, and cloud work. Plenty more, including current builds, available on request.
