Back to original languageAbout Baptiste
Hi đź‘‹ I'm Baptiste, a freelance full-stack engineer focused on Angular + Spring Boot + PostgreSQL for B2B SaaS and business applications. Available for EU hours from Montreal.
🎯 Where I am most useful
Specialized support for Angular and/or Spring Boot B2B SaaS — architecture, code review, unblocking critical features, legacy refactoring
Short technical audit (10 days) — cloud costs, DB performance, technical debt, security — quantified report + roadmap
Part-time Fractional CTO (2 days/week, min 3 months) for teams of 2-10 devs without a CTO — architecture scoping, CI/CD, GitOps, mentoring
Complete build of a B2B SaaS MVP on Angular + Spring + Stripe + K3s — fixed price quote
🛠️ Stack
Frontend: Angular 17+ (signals, standalone, SSR), strict TypeScript, Astro
Backend: Spring Boot, DDD-lite, JWT, multi-tenant, NestJS on demand
DB: PostgreSQL + Flyway, Prisma
Infra & DevOps: Docker, K3s, ArgoCD, GitHub Actions, GitOps
Integrations: Stripe Connect, Brevo, Minio S3, OpenAI/Anthropic
Observability: Prometheus, Grafana, Loki
🎓 Background
4 years of full-stack experience, with a dual-track path:
Capgemini Engineering: major clients: SYTRAL (Lyon public transport), Hermès (luxury/retail). Enterprise standards, transactions, security.
Freelance in parallel: complex systems for high-load tech gaming communities: transactional banking, real-time multiplayer, group management. Concurrency, latency, production debugging without test environments.
Today: 100% focus on EU B2B SaaS + 2 SaaS delivered in production on my own stack (caribBook, DayZBeansLauncher).
âś… What you can expect
Typed, tested, documented code, your Git repo, zero lock-in
Weekly demos, clear reporting, responsive communication during EU hours
100% standard stack: any EU developer can take over the project without rewriting
Honest approach: if your current stack (React/Next/Supabase) works, I'll tell you. No dogmatic migration.
