Backend Magic with Node.js | Clean Code, Real Results

I build server-side magic using Node.js, and I'm all about clean code, strong logic, and making things 'just work'. From quick API setups to full-blown backend systems- I've got you. Here's what I can help you with: -Backend development with Node.js + Express -Creating RESTful APIs or real-time features (yep, chats too!) -Working with MongoDB, PostgresSQL, Firebase -Setting up third-party integrations (Stripe, Twilio, you name it) -Deploying to Vercel, Heroku, or wherever your app needs to live -Cleaning up legacy code and making it shine again I've worked with startups, solo founders, and growing teams - always focusing on building things that are stable, scalable, and easy to maintain. Clients say they love my: -Fast communication (I don't ghost!) -Attention to detail -Ownership of the project -Transparent and clear process If you're looking for someone who gets things done without the hassle - let's talk. I'm ready when you are.
