About Caryl
AI Developer & Process Automation Engineer | n8n, make, zapier & LLM
Paris, France - 12:57 pm local time
I build automation systems that function as profit centers. I specialize in architecting production-grade workflows that generate massive financial returns, such as contributing to a $2,000,000 Seed funding round and driving $150,000+ in annual operational savings.
Proven Financial Impact & ROI:
- SaaS Revenue & Scale ($1.6M+ ARR Potential):
Architected automated growth loops driving a 14,000+ user increase. By industrializing acquisition, I achieved a 57% YC cohort acceptance rate, placing the startup on a trajectory for multi-million dollar valuation.
- 80% R&D Capital Preservation:
Engineered a "Prompt-to-App" pipeline that slashed development costs by 80%. Transforming 6 months of manual dev at a cost of ~$100k. in Production-ready MVP in 48 hours. This velocity allowed my cliets venture to secure their first paying enterprise client within 14 days of launch.
- $145,000+ Operational ROI:
Automated structured extraction for 1,000+ NASDAQ reports. This replaced 1,500+ manual analyst hours (valued at $100+/hr), eliminating human error in high-stakes financial modeling for a YC W25 venture.
- High-Velocity Market Capture:
Hard-coded and deployed an autonomous AI agent for Private Equity in 48 hours. This system analyzed investment moats for opportunities worth up to $15,000,000, turning weeks of due diligence into seconds of automated reasoning.
If you are looking for an architect who can turn your technical requirements into a competitive financial advantage, let's connect! I combine the "high-velocity execution" of Y Combinator with the analytical precision of an University of Oxford CS Student.
