About this gig
Most AI systems that fail don't fail on the model. They fail on everything around it no caching, no fallback when a provider times out, costs nobody forecast, an architecture that worked for ten users and won't survive a thousand.
I review AI systems and tell you plainly what's wrong and what to fix first.
What you get
- A written assessment: what holds up, what won't, and why
- Specific fixes ordered by impact, not a catalogue of everything theoretically improvable
- Cost and latency analysis where you're overspending and where it's justified
- An honest read on whether your stack fits the problem
What I look at
LLM integration patterns, RAG pipelines, agent design, API and backend architecture, deployment and scaling. Where relevant, how your AI and on-chain components divide responsibility.
I build these systems in Python, Go, and Rust this isn't theory. I'll tell you when something is fine as it is, and when a simpler approach beats what you've built.
Send a repo, a diagram, or just a description of what you're running, and I'll tell you what I'd look at first.

I build AI systems that make it to production — not demos that break under real traffic.
My work is AI agents, LLM integrations, and the backend underneath: pipelines, APIs, and services in Python, Go, and Rust. I also ship smart contracts and dApps on EVM chains, and increasingly projects where AI and on-chain systems meet.
Before freelancing: 3 years as a senior backend engineer at pCloud. IBM AI Developer certified.
Have something half-built that needs to be production-grade? Send me the details and I'll tell you honestly if I'm the right fit.
