Oleksandr Ryzhykov

Fullstack developer and DevOps engineer with 17+ years of hands-on experience. I work entirely independently — from design and markup to server infrastructure setup. Freelance only, no employment — that's always been my way of working.

Stack: WordPress, WooCommerce, MODx, OpenCart, Astro, Node.js, MySQL, MariaDB, PostgreSQL, Linux, Nginx, Cloudflare. In recent years I've been actively working with AI infrastructure — self-hosted LLMs, automation, and integrating AI into existing products.

I have experience in e-commerce (including international projects), web design (Photoshop, Illustrator — logos, banners, packaging), and server setup from scratch: SSH, SSL, Nginx, systemd, CI/CD.

I can help with building a site from scratch or improving an existing one: bug fixing, mobile adaptation, performance optimization, form integration, basic SEO setup, deployment to hosting/VPS.

I take work seriously: I dig into the task until it's done, keep in touch with the client, and don't abandon projects halfway. When something gets complicated — I find a solution, not an excuse.

Available for both small tasks and long-term projects. Write — we'll figure it out.
