✅ Node.js · NestJS · Django/DRF · React · Next.js · TypeScript · PostgreSQL · Docker

I build reliable, scalable web applications — from clean REST APIs and microservices to full-stack products with polished frontends. I work across the entire stack and take ownership of infrastructure too.

⚡️ 𝗪𝗵𝗮𝘁 𝗜 𝗰𝗮𝗻 𝗱𝗼 𝗳𝗼𝗿 𝘆𝗼𝘂:

+ Build or extend back-end APIs (NestJS, Express, Django/DRF)

+ Develop full-stack web applications (React, Next.js + Node.js/Django)

+ Set up and manage server infrastructure (Docker, VPS, Nginx, CI/CD)

+ Integrate third-party services and payment systems

+ Improve and refactor existing codebases

𝗖𝗼𝗺𝗽𝗲𝘁𝗲𝗻𝗰𝗶𝗲𝘀:

⚒️ Back-End: NestJS, Express.js, Django/DRF, Node.js, TypeScript, GraphQL, WebSockets, Celery (Beat & Worker), Redis, JWT, AWS Cognito

⚒️ Front-End: React, Next.js (SSR/SSG), Redux, Zustand, D3.js, Chart.js, styled-components, Material UI, Ant Design, SCSS/SASS

⚒️ Databases: PostgreSQL, MySQL, MongoDB, Supabase — TypeORM, Prisma, Sequelize

⚒️ DevOps & Infrastructure: Docker, Docker Compose, Nginx, PM2, GitHub Actions, GitLab CI, VPS setup & management, SSH, DNS, SSL certificates, Cloudflare

⚒️ Cloud & Storage: AWS (S3, EC2), Cloudflare R2, Firebase, Supabase, GoDaddy

⚒️ Monitoring: Sentry

⚒️ Third-Party Integrations:

❇️ Payments: Stripe, Monobank, PayPal, Webhook solutions

❇️ Messaging: SendGrid, Mailjet

❇️ Documents: PandaDoc

❇️ CMS: Strapi, Contentful

❇️ Auth: AWS Cognito, JWT, OAuth2

❇️ AI: OpenAI API

❇️ Other: AWS Amplify, Firebase

On the back end, I build production-grade REST APIs and microservices using NestJS (TypeORM, PostgreSQL, WebSockets, GraphQL, Redis) and Django/DRF (PostgreSQL, Celery for async tasks, background workers). I focus on clean architecture, performance, and maintainability — whether it's a greenfield project or extending an existing codebase.

On the front end, I build responsive, performant UIs with React and Next.js — covering SSR/SSG, state management (Redux, Zustand), and third-party API integrations.

For infrastructure, I handle the full DevOps cycle: Docker containerization, CI/CD pipelines (GitHub Actions, GitLab CI), Nginx reverse proxy with SSL, VPS provisioning, and cloud storage with AWS S3 or Cloudflare R2.

I take pride in clear communication, clean code, and delivering work I'd be happy to put my name on.

Looking forward to hearing from you!

I'm ready to start 𝗔𝗦𝗔𝗣 🔥
