AI Platform Improvements — Query Fan-Out, Source Tracking & Prompt Management
Working with Onyekachukwu was a great experience. He quickly understood the complexities of our AI platform and delivered high-quality improvements across query fan-out analysis, source tracking, and prompt management.
The features were implemented cleanly and efficiently, especially the handling of large datasets and the improved source classification system. The new bulk prompt actions also made the platform much easier to use.
Communication was clear and professional throughout, and all tasks were delivered on time.
Onyekachukwu is a reliable developer, and I would gladly work with him again.

Project Discovery & Technical Onboarding — Retention OS (5 hours)
Onyekachukwu did an excellent job during this discovery and onboarding milestone.
He took the time to understand the product vision, architecture, and documentation, and provided clear, thoughtful feedback. His questions were relevant, his analysis structured, and his recommendations helped identify gaps early and strengthen the foundation for development.
Communication was smooth and professional, and his written feedback was clear and actionable. This milestone delivered exactly what it was meant to: clarity, alignment, and readiness to move forward.
I would highly recommend Onyekachukwu for SaaS projects requiring strong analytical thinking and solid technical judgment.
