End-to-End Fullstack Development: React, Next.js, NestJS, TypeScript
Fullstack Developer, 3.5 years of commercial experience. I build web applications end-to-end: from databases and APIs to user interfaces and deployment.
Tech Stack: TypeScript, React/Next.js, Vue/Nuxt, NestJS, Node.js, PostgreSQL, AWS.
How I can help your business:
- Full-cycle web application and website development from scratch (e-commerce, marketplaces, landing pages, admin panels)
- REST API development, third-party integrations, PDF document generation
- Telegram bots and AI automation (scraping, summarization, auto-posting)
- Refactoring and feature enhancements for existing projects, performance optimization
I run my own e-commerce project in production, so I understand business needs beyond just writing code: conversion rates, loading speed, and SEO.
I actively leverage AI tools in my workflow, which speeds up development without compromising quality.
Quick to respond, honest with deadlines, and strict about keeping them.
