Frontend / Full-stack Developer

I build production-ready web applications for real businesses — from ERP systems and e-commerce platforms to internal dashboards and freelance client work. Comfortable across the stack: Frontend, Backend, Database, and Deployment.

About

Developer focused on real production work

I'm not into demo apps. My focus is shipping useful systems that businesses run on every day.

I'm a web developer with hands-on experience building real-world business systems — sales platforms, ERP modules, internal tools, dashboards, and client-facing web apps.

My strong side is Frontend with React, Next.js, and Vue 3 — but I'm comfortable working with Backend APIs, databases, deployment pipelines, and modern AI coding tools. I can take a feature from requirement to production.

My strength is reading requirements quickly, translating business problems into system flows, and owning the work end-to-end — from UI all the way to deployment.

What I bring
  • Translate business requirements into clean system flows
  • Own features end-to-end: UI, API, database, deployment
  • Comfortable with legacy databases and real production constraints
  • Use AI coding tools (Claude Code, ChatGPT) to ship faster, not just generate code
