I'm a Node.js Backend Developer and MERN Stack Developer who builds the parts of an application where mistakes are expensive: authentication, payments, transactions, and real-time systems. My focus is the backend: REST APIs, MongoDB schema design, Stripe payment flows, secure authentication, caching, and scheduled jobs. I can also build the React frontend, so you don't need to hire a second developer to get a working product from database to screen. I've built a two-sided freelance marketplace with escrow wallets, milestone payouts handled as atomic MongoDB transactions, JWT access and refresh tokens, 2FA by SMS and email, real-time messaging, and an admin panel for disputes and user management. If you need payments, accounts, or live features done carefully, that's where I'm strongest. I also bring Python to the table. I have years of experience building scraping and automation tools, so I can collect, clean, and structure data for research or AI/ML projects. My main stack includes Node.js, ExpressJS, MongoDB, Stripe, JWT, Socket io, Redis, React.js, and Next.js, with Python for scraping and automation. 🛠️ WHAT I CAN HELP YOU BUILD • Node.js and Express REST APIs • Stripe payments, escrow wallets, payouts and webhooks • Authentication, 2FA/OTP and role-based access control • MongoDB schema design and atomic transactions • Real-time chat, notifications and live updates (Socket io) • Redis caching and performance improvements • Scheduled jobs, billing cycles and background tasks (cron) • Marketplace and platform backends • Admin panels and user management systems • React.js frontends when you need the full product • Web scraping and data extraction (Python) • Automation and data pipelines for AI/ML use • Bug fixing, API cleanup, and improvements to existing backends 🏆 RECENT WORK - Repos on GitHub • Freelance marketplace platform: escrow payments, milestone releases, contracts (fixed-price and hourly), weekly billing via cron, real-time messaging, and dispute resolution in the admin panel • Job scraping web application: automated data collection with a clean front end • Scraping and CSV export workflows using Apify actors and Node-based automation ⚙️ HOW I WORK 1. Understand your business logic and data model before writing code. 2. Break the work into clear, testable deliverables. 3. Validate inputs, handle errors, and log failures so problems are visible. 4. Take extra care wherever money moves: transactions, edge cases, failure states. 5. Communicate clearly and update you along the way. 6. Leave the codebase easier to understand than I found it. 💻 CORE STACK Backend: Node.js, Express, REST APIs, Socket io Data: MongoDB, Mongoose, Redis Payments & Auth: Stripe, JWT, bcrypt, 2FA / OTP, Zod validation Frontend: React.js, Next.js, React Router, JavaScript, Tailwind CSS Scraping & Automation: Python (Selenium, BeautifulSoup, Pandas) Tools: Git, GitHub, Postman 📩 LET'S TALK Tell me what you're building, where things are stuck, and when you need it done. I'll look at the details and come back with a clear plan and an honest estimate.
