What I'm looking for

I seek remote, part-time roles (≈20 hrs/week) in teams that value clean architecture, code quality, and professional growth, working on modern frontend projects with opportunities to contribute full-stack or Web3 features.

I am a frontend-focused full-stack developer with 5+ years of commercial experience building real-world products—from multilingual real-estate platforms to SEO-optimized e-commerce sites and Web3-integrated automation. I founded multiple e-commerce projects where I designed and implemented full IT infrastructure, including online stores, product management tools, automation systems, and integrations with payment, warehouse, and messaging services.

I prioritize modern frontend development (React, Next.js, Astro), clean architecture, and code quality while actively improving skills and following industry best practices. I have hands-on backend, Web3, DevOps, and SEO experience, and I am available for remote work (20 hours/week), seeking teams that value professional growth and maintainable systems.
