I'm a frontend developer with over 4 years of commercial experience — and I don't just «write React components». I've been through fintech, complex B2B systems, and full‑cycle freelancing, so I know exactly how to turn vague requirements into working, reliable products.
My main stack is React, TypeScript, Next.js, but I'm comfortable going beyond the frontend:
- Backend tasks with NestJS (product modules, shopping carts, payment integrations)
- CI/CD setup
- Nginx + SSL configuration
- PostgreSQL & MySQL
I build SPA and PWA applications that are fast, maintainable, and scalable.
What you get working with me:
- full ownership — I don't need someone to hold my hand. I solve problems independently
- business‑oriented thinking — I care about deadlines, performance, and real user value, not just clean code
- mentorship & team skills — I've mentored juniors, helped shape frontend conventions, and worked smoothly in Scrum teams
- end‑to‑end mindset — from architecture decisions to Nginx config and AI integrations
Recent highlights:
- built a dashboard + table builder from scratch for a logistics system
- migrated state management from Redux Thunk → RTK Query (less code, fewer bugs)
- developed a UI kit based on ShadCN and Ant Design
- integrated payment systems and documented APIs with Swagger
- Configured production servers and HTTPS
I'm best for:
- long‑term freelance projects
- full‑stack / frontend intensive tasks
- startups and product teams needing a reliable contractor
- maintenance, optimization, or building from scratch.
