Launching a SaaS or already have a product, but the technical side is becoming a bottleneck (deployment, stability, infrastructure, technical debt)?
This is usually when I step in.
I help transform an MVP or an idea into a truly usable product: a clean architecture, reliable deployments via CI/CD, and Docker/AWS infrastructure that lasts.
What sets me apart is my ability to handle the entire scope without breaking it down: backend development (Symfony, FastAPI), infrastructure (Docker, Terraform, AWS), and deployment. No need to align multiple Dev + DevOps profiles to move the project forward.
Recently, for example, I built a marketing automation SaaS platform in 6 weeks with:
- automatic instance creation per client
- multi-tenant & single-tenant architecture
- complete deployment (Docker, GitLab CI/CD, monitoring, backup)
- centralized authentication (SSO: Keycloak | Authentik, OIDC & Oauth2)
- subscription management with Stripe
I regularly work on projects such as:
- SaaS creation (from idea to deployment)
- taking over existing projects (refactoring, stabilization, performance)
- infrastructure setup (Docker, AWS, CI/CD, automation)
My goal is simple: to provide you with a reliable, maintainable, and scalable product.

Experience
- Eweb AgencyCreation of a Marketing Automation SaaS platformTECHFebruary 2026 - April 2026 (2 months)Paris, FranceDevelopment of a marketing automation SaaS platform from a starter kit (Next.js) and Mautic (Symfony/PHP), an Open-source application.I designed and implemented the entire technical architecture to transform an existing base into a usable SaaS product.The work involved developing an automatic provisioning system to create and manage client instances based on their subscription, via a dedicated internal API.I also built a complete infrastructure based on Docker (Traefik, Grafana monitoring, Restic backup), with a multi-instance logic (one database + one domain name per client).The entire system was secured (VPN, access segregation) and industrialized via CI/CD (GitHub Actions) with a private registry.One of the main challenges was unifying authentication between several initially independent applications, each with its own user management.The implementation of SSO (Keycloak) required adapting authentication flows and user models to ensure global consistency and a smooth experience.→ This work helped avoid duplicates, account inconsistencies, and experience breaks.→ Delivery of a functional SaaS with a stable and automated infrastructure in 6 weeks.
