About
I'm a full-stack developer and founder of Coded Letter, combining a Fine Arts background with years of production work across headless commerce, custom WordPress ecosystems, React applications, and product R&D.
I work with agencies, studios, and direct clients to design, ship, and maintain fast digital products—from WooCommerce storefronts and Gatsby or Next.js sites to automation, prototypes, and creative tooling. I'm also the author of my own WordPress and WooCommerce theme work, and I regularly work across React, Python, shell scripting, server management, and monitoring.
I learned coding on my own, starting with SoloLearn where I completed 15+ comprehensive courses across PHP, Python, C#, JavaScript, and more. Back when I was still studying, I was also teaching coding online using the Glitch multiuser editor, and my journey really began around the age of 12 or 13 when I wrote automation and hack scripts for a popular MMORPG.
