About

I'm a senior full-stack web developer and Computer Engineer who works across the whole stack, from front-end layouts and responsive design to back-end functionality, integrations and databases. Most of my work is building and maintaining business websites and online stores that are fast, easy to manage and built to rank.

On the web side, I have deep experience with WordPress, including the Genesis Framework and Elementor, and with e-commerce platforms such as Shopify and Volusion. I also build custom web applications in PHP, MySQL and ASP.NET, and I handle SEO and performance optimization so every site ranks well in search and keeps performing after launch.

As an IoT engineer, I design connected systems end to end: Arduino-based sensors collect real-time data, APIs and databases store it, and web dashboards present it with alerts, reports and AI-powered insights. My engineering background lets me bridge hardware and software in a way most web developers can't.

I work with AI every day

AI isn't an add-on for me. It's built into how I plan, code, optimize and deliver, so clients get better results in less time.

Build faster

AI-assisted coding, debugging and testing let me deliver websites and features quicker, with fewer errors.

Rank higher

I use AI for SEO research, content optimization and technical audits to help sites climb in search results.

Smarter systems

I build AI into client projects, from automated alerts and summaries to reports that write themselves.
