I am committed to delivering high-quality work, meeting deadlines, and maintaining clear communication with clients. Whether you need a new application, improvements to an existing system, or technical support, I am ready to help.

I specialize in back-end development using Python and Django, leveraging three years of experience to create efficient, scalable solutions. My journey began with internships and competitions that sharpened my skills in cutting-edge technologies like Typescript, NextJS, GraphQL, and Material UI. I have successfully contributed to projects at a government agency focused on advanced science, showcasing my ability to deliver robust applications under real-world conditions. If you're seeking a developer who can balance technical expertise with a creative approach to problem-solving, let's connect. I am eager to understand your project needs and collaborate to turn your vision into reality, providing both quality and innovative solutions.

I build reliable, well-structured web applications from database to UI and I've spent the last two years doing exactly that in a real healthcare environment, where systems can't fail and data integrity matters. My core stack is Ruby on Rails and Laravel/PHP for the backend, with React and Node.js for modern frontends. I've worked on patient management systems, cross-database integrations with legacy hospital systems, background job processing with Sidekiq, and CI/CD pipelines on GitLab. Here's what working with me looks like: • You get clean, maintainable code, not quick hacks. • I understand the full request lifecycle: from DB queries and N+1 optimizations, to API design, to what the user sees in the browser. • I communicate clearly and proactively, especially when I run into blockers or need to clarify scope. • I'm comfortable in ambiguous, evolving codebases, government and healthcare systems have taught me that. Whether you need a Rails API wired up to a React frontend, a Laravel system extended or debugged, or a new web app built from scratch, I can scope it, build it, and ship it. Let's talk about what you're building.

I build fast, accessible, and reliable web applications — and I've taken an unconventional road to get here. My engineering foundation started at the Philippine Science High School and UP Diliman, where I first fell in love with programming. When financial circumstances forced me to step away from university, I didn't stop — I adapted. I spent years as a Top-Performing Sales Agent at Concentrix, handling 30+ calls a day for AT&T and General Motors accounts, developing the communication precision, pressure resilience, and problem-solving instincts that now shape how I approach engineering challenges. In January 2022, I bet on myself and enrolled at Avion School to make the full pivot into tech — and I haven't looked back since. Today, I'm a Software Engineer II at HCL Technologies, where I own and deliver full-stack features across the entire lifecycle: translating Figma designs into pixel-perfect React + TypeScript + MUI interfaces, building and maintaining Node.js + PostgreSQL backends, writing automated tests with Jest & React Testing Library, and deploying through Jenkins CI/CD pipelines on AWS inside Docker environments. I also actively leverage and contribute to HCL's open-source Enchanted Web Components framework, and I integrate modern AI-assisted tools — GitHub Copilot, Windsurf, and Claude — to consistently ship high-quality work. What I bring to a team: → Full-stack ownership from UI to backend to deployment → A sharp eye for translating design intent into clean, maintainable code → Battle-tested composure in fast-paced, high-stakes environments → A growth-driven mindset — self-taught, resilient, and always leveling up

I’m a React and React Native developer with 4+ years of experience building production mobile and web applications. I currently work on mobile apps used in real-world maritime operations, focusing on offline-first systems, data synchronization, and performance in unstable network environments. I specialize in React Native (Expo & CLI), TypeScript, and building scalable, maintainable applications. I also have experience with React JS and Ruby on Rails, which helps me understand full-stack systems and build better integrations. I focus on writing clean, reliable code and delivering features that work in real-world conditions. I’m comfortable working independently or as part of a team. If you’re building a serious product and need a reliable developer, I’d be happy to help.
