Backend Developer (Node.js / NestJS)

Budget: 4000 PLN Deadline: 1 day

Hello, I worked on the project Folder ✅ – I created scalable APIs for 15+ services with NestJS and TypeScript, databases optimized for 1 million requests per day.

How do you plan to scale the backend with increased load: by adding caching or vertical scaling?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

Hi Edward,

I’m really excited about the chance to work on your project as a Full Stack Developer. I’ve spent several years building applications with React, Next.js, Node.js, and NestJS, and I enjoy taking features from initial design all the way through to deployment. I’m comfortable designing database models, creating secure and high-performance APIs, and making sure the frontend and backend work together seamlessly.

TypeScript is my daily driver, and I make sure to use modern tooling and best practices to keep code maintainable and scalable. I also have experience with DevOps pipelines, automated testing, and deployment automation, so I can help ensure that the features I deliver are reliable and production-ready.

In my previous projects, I’ve often taken full ownership of features, working closely with designers and stakeholders to deliver measurable improvements and results. I’d love to bring that same approach to your project and help you build something that works smoothly and effectively.

Looking forward to hearing more about your goals and how I can contribute.

Best regards,
