What I'm looking for

I’m looking for a team that values maintainable architecture and clean engineering practices. I want to build scalable full-stack features end-to-end, collaborate across frontend, backend, and QA, and contribute to user-centric products with room to learn.

I’m a full-stack software developer focused on writing maintainable, scalable, high-quality code while strengthening my technical expertise through modern frameworks and best practices. I’ve built and enhanced enterprise-grade applications across frontend and backend layers, always prioritizing reliable, user-centric outcomes.

From my React internship to my full-stack work with Spring Boot and Vue.js, I’ve contributed to state management, API integrations, RESTful services, and performance improvements. I’ve also implemented thorough testing and validation workflows using Selenium, Cypress, Formik/Yup, and mock testing to reduce regressions and keep features dependable.

As a Founding FullStack Engineer at Waydev Inc., I architect and maintain Vue.js and Laravel systems with domain-driven module boundaries and reusable service layers. I leverage TanStack Query for server-state orchestration and optimize performance through query analysis, eager loading strategies, database indexing, caching, code splitting, and lazy loading—while also supporting Waydev AI and leading full-stack platform release execution.
