Axel Vincent

I provide my clients with a software engineering offering, capable of taking on end-to-end development projects, all the way to the CTO role.

Trained in high-quality software development at scale-ups like Kapten (Freenow), Swile, and Shares, and in bootstrapping my own SaaS (Ritchy) across eight European countries as CTO, I have been designing and deploying production products for over eight years.

Technology Stack:

- Backend: Node.js, Express, TypeScript, PostgreSQL, Redis

- Frontend: React, Vite, TypeScript

- Infrastructure: Docker, Kubernetes, Railway, Grafana, PostHog

- AI: LLMs, RAG, evaluations, agents, harness engineering in the cloud

I've used each of these technologies in production.

Recent achievements:

- Mainstream (AI) -> RAG assistant for coaching and closing. MVP shipped in 4 weeks, 115k users, 2M+ messages, 99% uptime.

- Lead Club (AI, ongoing) -> coding harness that drives market research and generates static and on-demand video ads.

Past achievements:

- Ritchy (CTO) -> B2B Prospecting SaaS with waterfall enrichment and AI sourcing, bootstrapped to 60k ARR

- Shares (Backend) -> Designed and maintained backend systems for a social investing platform, working on high-reliability financial features at scale within a fast-growing fintech.

- Swile (Fullstack) -> Owned fullstack features for an employee benefits super-app, contributing to both product evolution and internal tooling across a high-growth scale-up environment.

- Kapten (Backend) -> Owned payment infrastructure for a ride-hailing platform, building robust and secure transaction flows handling high volumes in a regulated environment.
