About this gig
Are you looking for a high-performance, secure, and highly scalable web application?
I specialize in building custom, production-ready web applications, SaaS platforms, and real-time marketplaces using the modern JavaScript/TypeScript ecosystem. I don't just write code; I architect robust infrastructure designed to handle complex business logic, secure transactions, and real-time user interactions.
What I Offer:
- Modern Frontend: Blazing fast, SEO-optimized user interfaces using Next.js , React, and Tailwind CSS.
- Robust Backend API: Scalable server logic using Node.js and Express.
- Real-Time Features: Live messaging, notifications, and presence tracking using WebSockets and Redis Pub/Sub.
- Advanced Database Architecture: Complex schema design using PostgreSQL, MongoDB, and Drizzle ORM.
- Enterprise-Grade Security: Layered authentication (JWT Token Rotation, Google OAuth 2.0, TOTP 2FA) and strict Role-Based Access Control (RBAC).
- Payment Integrations: Secure, duplicate-free financial transactions via Razorpay with robust webhook handling.

FAQ
Can you handle payment gateway integrations?
Yes! I have extensive experience integrating payment gateways like Razorpay with robust backend webhook handling, HMAC-SHA256 signature verification, and secure transaction state management for marketplaces and e-commerce.
How secure will my web application be?
Security is a priority. I implement robust systems including JWT-based access and refresh token rotation, OAuth 2.0, multi-session tracking, Zod request validation, and tiered rate-limiting to prevent attacks.
Will you deploy the application?
Yes, I can assist with deploying your frontend to platforms like Vercel and setting up your Node.js backend and databases on your preferred cloud hosting provider.
What do you need from me to start?
Please provide a detailed overview of your project requirements, any wireframes or UI designs (like Figma), and a list of specific third-party APIs or features you need integrated.
