About Me

I build and scale enterprise web platforms where frontend architecture, product thinking, and engineering rigor directly affect revenue, delivery speed, and operational cost.

My work spans React, Next.js, TypeScript, Node.js, design systems, and GenAI workflows. Across large teams and distributed environments, I focus on reducing complexity, improving reliability, and making products faster to ship and easier to maintain.

In recent work, I have led frontend architecture for 10K+ user platforms, driven measurable performance gains, reduced production defects through stricter engineering practices, and integrated Claude and OpenAI into production workflows to automate manual processes and improve accuracy.

I care about systems that are simple to use, resilient to change, and built with long-term maintainability in mind. This portfolio exists to show that combination clearly: product impact, technical depth, and practical leadership.

If you are hiring for senior frontend, product engineering, or AI-enabled platform work, the best next step is the contact section.

About Resume Web

Resume Web is the public home for my professional profile. It keeps my work, capabilities, and current focus in one place so hiring teams and collaborators can review it without friction.

I keep the site aligned with my resume so the content remains factual and current. It is also where I validate modern frontend standards in a production Next.js app: performance, accessibility, structured data, and a lean interactive surface.

The current version uses Next.js, React, Tailwind CSS, static rendering, and a small set of client-only interactions to keep the experience fast and maintainable.
