Full Stack Developer
Merida, Philippines - 11:18 pm local time
I’m a Top-Tier Full-Stack Developer with 5+ years of experience delivering scalable, production-ready web applications for startups, businesses, and public-sector clients.

I specialize in building reliable, high-performance systems—from SaaS platforms and ERP systems to internal tools and APIs—while owning features end-to-end, from architecture to deployment.

What I deliver:

- Modern, responsive frontends using Vue.js, Nuxt.js, TypeScript, and Tailwind CSS
- Secure, scalable backends with Node.js (NestJS, Express) and PHP (Laravel)
- REST & GraphQL APIs with authentication, authorization, and integrations
- Optimized databases using PostgreSQL and MySQL
- Production deployments using Docker, AWS, CI/CD, and Linux servers

How I work:
- Clean, maintainable, and well-documented code
- Strong focus on performance, security, and scalability
- Test-driven development using Playwright, Cypress, Vitest, and Pest
- Clear communication, predictable timelines, and proactive updates

Proven experience with:

- SaaS platforms, ERP systems, POS systems, and government applications
- End-to-end development lifecycle: planning, development, testing, deployment, and UAT
- Tech Stack: JavaScript, TypeScript, Vue.js, Nuxt.js, Node.js, Laravel, PostgreSQL, MySQL, Docker, AWS, REST, GraphQL
