Back to original languageAbout Lucas
Your SaaS has just signed a major client, raised funds, or registrations are exploding. And then, your backend starts showing signs. Unexplained latences, production crashes, accumulating timeouts.
This isn't bad luck. It's technical debt waking up at the worst possible moment.
The Backend Health Check: 4 days to see what your system is hiding.
I start with a 45-minute call to understand your product, your context, and the fragilities you're already feeling. After 5 days of analysis, you'll receive your **3 critical fragilities**, their risk level, and the action plan in the right order. If not, **you pay nothing**.
For teams that want to go all the way, I intervene in implementation to fix what we found: refactoring, architecture, AWS optimization, AI agent integration.
Why me?
4 years at Capgemini on Java/AWS backends for major clients in insurance and aeronautics. Performance, resilience, maintainability non-negotiable from the start. It's this rigor that I now bring to growing SaaS companies, before scalability becomes urgent.
