Good Vibes Gone BadAI wrote your code.
Can your business trust it?
I find out what's solid, what's risky and what's about to break, then I fix it.

SurveyStackThe problem
It works. But can you depend on it?
Someone on your team built it with AI. Now the business depends on it, and nobody can say for sure what's under the hood.
I review it the way a CTO would, tell you in plain English what's solid and what's risky, and fix what can actually hurt you.
Check my codeIs our data safe?
Exposed keys, open endpoints, customer data anyone can reach.
Will it hold up as we grow?
Fine with 10 users. What about 1,000, or your busiest day?
Would you know if it broke?
No alerts, no logs. You find out when a customer complains.
What if the builder leaves?
If the only documentation is one person's chat history, that's a risk.
What I check
The boring stuff that keeps a business running.
AI is great at making things work. It's bad at the parts nobody sees until something goes wrong. That's where I look.
Security and access
Who can see what, where your keys live and what's exposed to the internet.
Secrets · Auth · Validation
Data
Whether your data stays fast, correct and recoverable as it grows.
Indexes · Migrations · Backups
Monitoring
Whether you'd hear about a problem before your users do.
Error tracking · Logs · Alerts
Performance
How it holds up under real load, on real devices.
Caching · Queries · Load time
Shipping changes
Whether a new feature can go out without breaking an old one.
CI/CD · Tests · Rollbacks
Structure
Whether the code is organized so the next change takes days, not weeks.
Architecture · Modularity
Integrations
What happens when a vendor, API or payment provider goes down.
Rate limits · Retries · Failover
Ownership
Whether anyone besides the original builder can run it and change it.

How it works
Audit, report, fix.
01
Audit
I go through your code, infrastructure, deployment pipeline and data, the same review I'd run before putting my name on a system.
02
Report
What's solid, what's risky and what's about to break, in plain English and ranked by what it could cost you.
03
Fix
I fix the highest-risk problems first, while the business keeps running.
Track record
I've built the systems that can't go down.
The problems in AI-built software follow patterns. I've seen them at scale, where they cost real money.
Defense autonomy
Go radar telemetry pipelines for Legion, Swarm Aero's command-and-control platform for UAS swarms. ITAR-controlled, on AWS GovCloud (US).
Enterprise voice AI
Complete serverless backend for Stanley Black & Decker's enterprise AI voice platform, across thousands of devices.
Key originally started as a regular Willow Voice user who gave feedback, but it was clear right away that he was a builder. He ended up building the early foundation of our iOS app entirely on his own time. That work gave us real momentum at a crucial point, and parts of what he built are still in the product today.
Key is a master engineer who employs the absolute best practices when it comes to software development. Highly recommend him for any projects you need done with good quality and expert handling.
Key is a top notch engineer. He is patient and understanding in communicating aspects of development that I've struggled to learn myself. Key helped me leverage what I know, integrate well-known design patterns and produce enterprise-quality apps. Need a great programmer and a wealth of knowledge to guide your team? Call on Key.
Truly a one-of-a-kind engineer that's dedicated to getting the job done while fighting for its users.
About
I'm Key Hoffman.
I've spent 13+ years building mission-critical systems for defense autonomy, Fortune 500 enterprise, fintech and marketplaces, from ITAR-controlled drone telemetry to AI voice platforms. I also build AI agents and MCP servers, and I use AI coding tools every day, so I know exactly where they cut corners.
Now I help operators make sure the software AI wrote for them is safe to run a business on. Based in Austin, Texas.
