Backend Developer (Node.js / NestJS)

Hello,
I’m an experienced Backend Developer specializing in Node.js, NestJS, and TypeScript, with a proven track record of building scalable and secure APIs for both web and mobile applications.

I’ve designed and deployed systems on AWS and GCP, optimized database performance with PostgreSQL and MongoDB, and implemented advanced authentication and caching strategies to boost reliability and speed.

My recent projects include backend architectures that improved scalability by over 60% and reduced infrastructure costs through efficient cloud resource management. I can provide code samples or architecture diagrams upon request.

I’d be happy to discuss how I can help design and maintain high-performance backend systems for your product.

… Feel free contact with me, thanks.

I have extensive experience in the technologies mentioned above and am ready to participate in your project.

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,
Jeo Vincent Carretas
