About this gig

Is your AI feature giving wrong answers, running slowly or costing too much?


I'm a senior .NET developer with 17 years of experience, and I build and maintain production AI features with the OpenAI and Claude APIs.


Common problems I fix:


  • Inconsistent or made-up answers Broken or unreliable JSON output
  • Slow responses and timeouts API bills higher than they should be
  • Prompts that only work some of the time
  • No handling for errors, limits or bad input


How I fix them:


  • Clearer prompts, with examples and fixed output formats
  • Structured outputs your code can trust
  • Caching, the right model for each task, and spend limits
  • Test sets, so you can see accuracy before and after


I work in C# and .NET, and in JavaScript or TypeScript. Not sure what's wrong? Start with the Health Check: you'll get a clear written list of fixes, whoever makes them.


Message me before ordering with what's going wrong and an example.
