About this gig

I will develop a powerful and scalable backend using Node.js, NestJS, FastAPI, Flask, or GraphQL/REST API based on your needs.

From simple CRUD APIs to complex SaaS, CRM, booking, e-commerce, or real-time systems I design secure and optimized server-side architecture, tailored for performance and extensibility.

Features I offer:

Authentication (JWT, OAuth, SSO)

Role-based access (RBAC)

Database design & optimization (PostgreSQL, MongoDB, Redis)

Payment gateways (Stripe, PayPal, LiqPay)

Real-time sockets (Socket.io, SignalR)

File upload APIs & cloud storage

Background jobs (BullMQ, Celery, cron)

Docker, CI/CD, Nginx, PM2 deployment

Web scraping & automation (Playwright, Puppeteer)

Need your API connected to an existing frontend or deployed to a VPS/cloud? Ill handle that too.

Tech stack: NestJS, Fastify, Flask, FastAPI, Prisma, TypeORM, PostgreSQL, Redis, Docker, GraphQL, REST, AWS.

Lets turn your idea into a rock-solid backend.
