Aël Gain
CTO at Manuscrit Cloud
Paris, Ile-de-France
Summary
👤
Senior🎓
Top SchoolAël Gain is a pragmatic CTO and fractional technology leader with 11 years of experience building cloud-native infrastructure, CI/CD and data pipelines for startups and enterprises from Paris. He currently leads Refractio’s effort to compute embeddings and build a search engine for moving images, combining ML inference stacks with production-grade DevOps. Previously he scaled and migrated complex systems on GCP/AWS—cutting cloud bills, simplifying maintenance and accelerating developer iteration—while deploying GPUs, Kubernetes, Milvus and VertexAI for real-time RAG and BERT workflows. Comfortable coding across Python, TypeScript and infrastructure-as-code (Terraform, Pulumi), he blends hands-on engineering with product-focused architecture and team hiring. Not obvious at first glance: he repeatedly shortens ML test-feedback loops and optimized expensive inference workflows to make research-ready models practical in production. Based in Île-de-France, he pairs systems-level rigour from roles at OVH and Thales with startup agility as a founder and fractional CTO.
