Ronnel Libiran

I am a results-driven Senior Full Stack Developer with over 10 years of experience building enterprise web applications, REST APIs, middleware services, and e-commerce platforms.

My expertise spans modern front-end frameworks (React, Next.js, Angular, Vue, Blazor), backend API development (Node.js, ASP.NET Core/.NET 8), and database management (SQL Server, PostgreSQL, MongoDB, MySQL). I have delivered production-ready solutions for major brands such as Smashburger and Jollibee North America, including customer-facing ordering platforms, loyalty and rewards features, secure payment integrations, and CMS-driven content.

I specialize in:
- Designing scalable full stack applications with clean, maintainable code
- Building and documenting RESTful APIs with OpenAPI/Swagger
- Integrating third-party systems (Olo, Paytronix, FreedomPay, Forter, Strapi, Yext, Braze, AWS, Firebase)
- Improving reliability with validation, error handling, caching, retry policies, and monitoring
- Automating deployments with Docker and CI/CD pipelines (GitHub Actions, Jenkins)
- Supporting quality assurance with unit and integration tests (Jest, Playwright)

I collaborate closely with product, QA, frontend, backend, and DevOps teams to deliver secure, scalable, and high-performance solutions that drive business growth. My goal is to provide clients with reliable technology that enhances customer experience and streamlines operations.
