About me:
I work as a full-stack Node.js developer with a focus on server-side logic, SSR/SSG, and SEO-oriented projects. I have experience developing and maintaining complex web applications, integrating third-party services and APIs, and working with existing codebases. I regularly launch projects into production: setting up deployment, CI/CD, working with VPS and cloud platforms (Vercel, Cloudflare).
In my work, I follow a structured approach to architecture, am familiar with microservice approaches and asynchronous service interaction (RabbitMQ, Redis). I have practical experience in building systems with a clear separation of responsibilities, which allows for easy scaling and support of projects in the future.
I use the following technologies for development:
- Html / Css / Scss / Tailwind / Styled Components
- JavaScript / TypeScript
- React / Next.js
- State management: Redux, Zustand
- Node.js
- Express / Koa
- NestJS
- REST API / GraphQL / WebSocket
- MongoDB / PostgreSQL
- ORM: Mongoose, TypeORM
- Redis
- RabbitMQ (microservice interaction)
- Git, Docker
- Postman, Swagger
- Deployment on VPS, Vercel, work with Cloudflare
- Integration of ChatGPT API, payment systems (Stripe, PayPal)
Always happy to help you, available 24/7
