## What I'm looking for

```text
I’m looking for a team where I can build end-to-end scalable web and mobile products—owning REST APIs, integrations, and offline-first UX—while applying clean architecture and performance optimization to real business and geospatial problems.
```

## About

```text
I’m a Full-Stack Software Developer with 3+ years of experience building scalable mobile and web applications, focused on clean architecture, strong API design, and performance optimization. I enjoy taking products from end-to-end—turning requirements into working systems that improve workflows and user experience.

In my freelance work (2022–Present), I delivered mobile applications, backend systems, and automation tools for 5+ clients across different industries. I designed and deployed scalable REST APIs with Node.js and Express, built cross-platform Flutter apps with offline support and API integration, and automated manual processes using Zapier and Make.

As a Software Developer Intern at CERSGIS (2023–2025), I built the GDZHIAO Collector App used by field officers to capture geospatial data with offline functionality. By integrating Firebase and Google Cloud services for authentication and data storage, and introducing internal tools, I helped increase team productivity by ~20%.

My projects reflect how I approach real-world problems: Cognify reduced administrative workload by ~40% through process automation, while the GDZHIAO Collector App improved reliability and data accuracy for field operations. From timesheet and productivity tracking (Worktivo) to campus navigation and hospitality automation, I focus on building reliable features, thoughtful integrations, and maintainable code.
