About Julien

CTO of a venture-backed PropTech for 5+ years. Built and scaled a multi-module SaaS platform from zero to a team of 20+

Today I help companies integrate AI into their existing products and build solid cloud architectures - no over-engineering, no tech debt.

What I bring:

LLM/AI Integration: Chatbots, intelligent automation, RAG, autonomous agents. I ship AI in production, not just demos

AWS Serverless Architecture: Lambda, CDK, DynamoDB, EventBridge. Systems that scale and cost what they should

CTO as a Service: Stack selection, architecture, dev process setup, technical hiring, code audits

Typical projects:
  • Integrating an LLM into your SaaS product (customer support, content generation, data analysis)
  • Designing or rebuilding a serverless architecture on AWS
  • ⁠Auditing your tech stack and prioritizing your roadmap
  • ⁠Setting up your dev team (processes, CI/CD, onboarding)

TypeScript · AWS · Next.js · Node.js · Claude/OpenAI · DynamoDB
