Fardin Khan

I am a Full-Stack Developer specializing in the MERN stack. I build high-performance web applications and e-commerce engines that automate business operations and drive growth. I focus on building systems that aren't just functional, but scalable and secure. By using professional tools like Redis caching and BullMQ, I ensure your platform stays fast and stable even during high-traffic sales or heavy user load.

How I can help your business:

Custom E-commerce Engines: Building high-conversion stores with secure Stripe payment orchestration, inventory management, and 100% data ownership.

SaaS & Productivity Tools: Transforming manual spreadsheets into real-time collaborative dashboards and automated workflows.

AI Integration: Implementing OpenAI, Gemini for automated product descriptions, smart data analysis, and predictive features.

Real-Time Ecosystems: Using SocketIO for live order tracking, instant notifications, and team synchronization.

Why work with me?

Production-Ready Code: I use Pino logging and Jest testing to ensure your app is maintainable and ready for real customers.

Performance Focused: I optimize every build with Vite and Redis for sub-second load times—because every second of lag costs you sales.

Clear Communication: I take full ownership of the project and keep you updated every step of the way.

The Tech Stack: React 18, Node.js, Fastify/Express, MongoDB, Redis, BullMQ, SocketIO, OpenAI API, Gemini API, Stripe, JWT/OAuth.
