Gig Summary

About this gig

I am a senior software engineer with 12+ years of experience building production-grade desktop GUI applications in C++, Qt, and PyQt, backed by robust SQL databases.

Businesses increasingly want AI inside their tools but browser apps can't match the privacy, offline access, and performance of a native desktop app. That's exactly what I build.

What I can do for you:

1) LLM integration (OpenAI, Claude, or local models) into Qt / PyQt apps

2) Local, offline AI apps for privacy-sensitive workflows

3) AI assistants, chatbots, and agent-style desktop clients

4) Smart document processing, search, and RAG knowledge tools

5) Custom desktop software, data tools, and internal business apps

6) Modernizing or adding features to existing desktop applications

I don't just write code I deliver working systems that solve a real business problem, with clean, maintainable, well-tested code and clear communication from start to finish.

Before ordering, please message me first with:

  1. A detailed description of your project
  2. Your budget
  3. Your expected timeline

I'll give you an honest assessment of what's possible and a fair quote.
