Project details
I build production-grade AI microservices that integrate LLMs, embeddings, scoring logic, and clean FastAPI endpoints. This project delivers a custom backend service designed for real applications, not demo, and includes structured JSON responses, async processing, and optional classification or routing logic.
Your service can power search, classification, automation, internal tools, or AI-driven workflows. All code is built in Python/FastAPI, fully Dockerized, documented, and delivered as a standalone system you control.
Perfect for SaaS teams, funded startups, and enterprise groups needing a reliable AI backend.
No calls required, but are optional. You’ll receive clear async updates and a fully owned, production-ready system.

Senior Python / Data Engineer — Deterministic Forecast Scoring Engine
I had the pleasure of working with Micahel, and I genuinely can't say enough good things about the experience. He was exceptional from start to finish.
What stood out most was that he felt more like a partner than a contractor. We pivoted many times throughout the project, and he was always willing to adapt his approach without friction. He clearly cared about the product itself, not just checking off tasks. He even offered thoughtful advice on my ideas—the kind of strategic input you typically don't get from a regular dev who's just heads-down in code.
His attitude was outstanding through every phase of the build. We ran into some significant challenges along the way, and he never once came close to giving up. He just kept pushing forward and finding solutions. His perseverance honestly made the difference between this project succeeding or stalling out.
On top of all that, he was a fantastic communicator. He responded to messages quickly, kept me in the loop, and consistently delivered on time. There was never a moment where I wondered what was happening or felt out of sync with the work.
Honestly, there isn't a single bad thing I could say about working with him. If you're willing to pay a bit extra for someone who treats your project like their own and shows up as a true partner, I'd recommend him without hesitation.

Senior AI / RAG Backend Engineer
Michael delivered exactly what we needed and then some. It’s rare to work with a true professional who genuinely cares about the quality of the product, not just completing the task. Michael brought technical skill, clear communication, and real ownership to the project from start to finish.
We brought him in to build a highly specific, citation-based retrieval system where accuracy mattered more than anything. He handled complex backend logic, document ingestion, and retrieval challenges extremely well, including multi-source querying, chunking improvements, and eliminating hallucination risk in responses.
What stood out most was his ability to diagnose and fix real problems, not just write code. Issues around retrieval quality, page mapping, and inconsistent results were identified quickly and resolved with thoughtful, practical solutions.
Communication was clear, technical, and honest throughout. When something needed to be reworked (like re-ingestion for improved chunking), he explained it directly and handled it without unnecessary back-and-forth.
He’s not just a developer, he understands systems and how they behave in real-world use.
If you’re building anything involving search, AI retrieval, or structured data systems, he’s the kind of developer you want leading it. We were fortunate to have the opportunity to work with Michael and look forward to having him continue as a key part of the project.

ScopePass – Phase C: Complete Platform Build
Michael transformed our product into something genuinely special. He went well above the scope and delivered a robust, well-engineered platform that we are incredibly proud of. His technical ability is outstanding and he approaches problems carefully rather than taking shortcuts. Michael is reliable, thoughtful and highly capable. If we needed similar work again, and we will soon, I would happily wait for his availability rather than hire another developer.
