01. About me

I am a WordPress and Next.js developer with 10+ years of experience, and I enjoy the craft side of building for the web: small interaction details, responsive layouts that do not fight the user, and codebases that are easy to keep improving.

Over the years I have worked across product teams, freelance projects, WordPress builds, e-commerce sites, and custom React/Next.js applications. That mix made me pragmatic. I like modern tools, but I like finished, reliable work even more. Today I work as a Senior Software Engineer at HTEC and build client projects as a Top Rated Plus freelancer on Upwork. I am also a Claude Certified Architect (Anthropic).

02. Interests and Hobbies

Outside client and product work, I keep a steady habit of exploring what is changing in the front-end ecosystem: CSS platform features, framework ergonomics, performance patterns, AI-assisted workflows, and the slow work of making developer experience calmer.

I also like projects where design and engineering meet. A good interface is not only pretty and not only correct; it has rhythm, restraint, and a little bit of kindness for the person using it.

03. Framework Preferences

For larger app surfaces I usually reach for React, Next.js, TypeScript, and Tailwind CSS. For content-heavy, marketing, or commerce work I am comfortable with WordPress, WooCommerce, and the smaller JavaScript needed to make those platforms feel custom without becoming fragile.

My default preference is boring where boring helps: simple data flow, clear component boundaries, accessible HTML, and just enough abstraction to keep the next change easy.
