What I'm looking for

I’m seeking frontend opportunities where I can build scalable, user-focused web applications. I’m available to join immediately and I enjoy improving UI quality with strong accessibility and validation.

I’m a Frontend Developer who builds and deploys React and Next.js applications, with a strong focus on scalable, user-focused web experiences. I enjoy turning UX details into robust UI outcomes—especially around accessibility and validation.

In open source work, I contributed to Rocket.Chat by resolving UI, accessibility, and validation issues in EmbeddedChat. I streamlined local development by containerizing the test environment with Docker, fixed emoji picker clipping on mobile using React Portals, and improved keyboard accessibility with Escape key dismissal.

I also delivered improvements through DIGI-UW—OpenELIS-Global-2 by implementing regex-based validation for National ID input and refactoring emergency contact data into a dedicated JPA domain entity. In my projects, I built StitchShop v2 as a full-stack e-commerce app with strict TypeScript type safety, and created a Medium-style content platform using Next.js ISR with Sanity.io, GROQ, and webhook-driven revalidation.
