Hire AI-First Engineer
Why Groovy
Company
How we added AI features to a 6-year-old system with zero downtime—after a previous attempt caused multiple outages.
A fintech company with a 6-year-old codebase needed to add AI-powered fraud detection and transaction categorization. Their previous attempts to "add AI" had been disastrous.
They had already spent $80K on a previous AI engineer—but nothing was production-ready.
"We tried hiring an AI engineer and letting them build on top of our system. It was a disaster. Everything they built broke our existing features."
AI layer listens to transactions—never touches transaction processing. If AI fails, transactions continue.
5% traffic to AI features. Monitor, adjust, expand. Instant rollback if anything looks wrong.
"The previous AI engineer we hired built everything directly into our codebase. When it broke, everything broke. Groovy built it as a separate layer that couldn't touch our transaction processing. Zero outages."

Yes. Our approach uses a sidecar architecture — AI features are built as separate services that sit alongside your existing system. They communicate through APIs without modifying core business logic. If anything fails, your original system continues running untouched.
This is common. We use AI-powered code analysis to reverse-engineer system behavior, map data flows, and identify integration points. Our AI agents can analyze thousands of lines of legacy code to understand patterns that would take humans weeks to document.
Our sidecar approach includes circuit breakers and automatic rollback. If the AI layer detects any degradation in the core system, it automatically disables itself. The existing system always takes priority — AI features are additive, never destructive.
Timeline depends on complexity, but typical engagements: AI feature addition: 4-8 weeks, full system modernization: 12-24 weeks. Our AI-First approach delivers 3-5X faster than traditional migration projects. Contact us for a timeline estimate.
Add AI features to your existing system without breaking what works. Zero-downtime migration guaranteed.
