AI & data systems that solve real problems
Hands-on technical delivery
Andrew Miller · Granville, Ohio
I build production agents and governed data platforms that connect siloed systems and put answers in front of the people making decisions. I evaluate what's real, prototype what's possible, and ship what proves out.
What I Solve
Patterns from recent production work: agents on real operational data, data platforms people can trust, and systems that hold up under scrutiny.
Agents that take bounded action
Multi-agent systems with tool calling, routing, and human-in-the-loop control — wired to real workflows, not demos.
> Designed and shipped agent systems that run against operational data.
Answers grounded in systems of record
Retrieval and grounding over curated enterprise data so answers stay tied to source tables, not loose document dumps.
> Built retrieval patterns on top of governed operational data.
Tools the model can safely use
Domain toolkits that let models query systems, take bounded actions, and return auditable results.
Data that lands with ownership
Pipelines that move operational data into shared platforms with clear contracts, ownership, and quality expectations.
Evaluation before and after go-live
Harnesses for quality, cost, and failure modes so you know what the system does when it breaks.
Governed data platforms
Access control, lineage, and compliance built into the platform from day one — so teams can trust shared data.
> 2024–2025. Built a governed data lake from the ground up. Presented at Google Cloud Next 2025.
Results
Governed data platform
Stood up a data lake with governance from day one so teams could trust and use shared operational data.
> 2024–2025. Architecture presented at Google Cloud Next 2025.
Production AI agents
Deployed AI agents on Google Cloud for a global financial services firm, with measurement tied to business outcomes.
> 2025. Hands-on delivery of agent systems in a regulated environment.
Zero-downtime platform replacement
Replaced a legacy platform processing millions in daily sales with a modern cloud system.
> 2020–2021. Zero downtime. Cut costs by 95% and maintenance by 50%.
Custom ops software
Moved a central Ohio manufacturer off NetSuite onto software shaped around how the operation actually runs.
Security and governance
Owned GDPR, PII, and governance compliance while responding to active cyber threats.
> 2020–2024.
Where this transfers
I focus on practical AI on operational data across siloed systems — integrating with the platforms you already run, and building for people who aren't engineers.
How I Work
I stay hands-on-keyboard. I design the system, write the code, and ship what I recommend.
- Identify the real problem, prove it with a working prototype on real data, then scale what works
- Prefer governed platforms and measurable evaluation over slideware demos
- Translate technical reality into outcomes operators and leadership can act on
- Make build-vs-buy calls from what things actually cost to run and maintain
Available for deep technical delivery: production agents, data platforms, and the integration work that keeps them reliable.
