À propos de ce service

I'm a senior software developer with 8+ years of experience building and scaling backend systems, most recently at Dayforce, an enterprise SaaS company, where I designed and maintained REST and GraphQL APIs handling high traffic loads.


I can help you with:

  • Designing and building REST or GraphQL APIs from scratch
  • - Optimizing slow SQL Server or PostgreSQL queries and schemas
  • - Adding authentication, validation, and error handling to existing APIs
  • - Database design, indexing, and performance tuning
  • - Integrating third-party APIs into your backend
  • - Writing clean, well-documented, testable code

My core stack is C#/.NET Core, Node.js/NestJS, TypeScript, SQL Server, PostgreSQL, Redis, Docker, and AWS. I also have experience with Python for scripting and data-focused backend work.


Send me a message with your requirements before ordering so I can confirm scope and timeline. I aim for clear communication, clean code, and on-time delivery.
