Service details
I will help you build or improve your backend systems so they are fast, scalable, and reliable in production.
Whether you are starting from scratch or improving an existing system, I can design APIs, optimise performance, and build backend architectures that handle real-world usage. I have worked on SaaS and workflow-driven platforms where performance and reliability directly impact business outcomes.
What I will deliver
- Backend APIs using Go with Gin or Nodejs with TypeScript using NestJS or Express
- Performance optimisation for slow APIs and inefficient database queries
- Scalable microservices architecture for growing applications
- Authentication and authorisation systems using secure practices
- Bug fixing, debugging, and reliability improvements
- Workflow automation solutions to reduce manual work
My approach
I focus on clean architecture, performance, and long-term maintainability. I design systems that handle failures, retries, and scaling from the beginning. This ensures your application performs consistently under load and is easier to extend as your product grows. I also prioritise clear communication and structured development so there are no surprises during delivery.
What I need from you
- Clear project requirements or idea
- Existing codebase, if available
- Expected timeline and goals
If your backend is slow, unstable, or not scaling properly, I can help you improve it and make it production-ready.
