Work

Proof, not promises. A data-first track record across energy and regulated finance, plus the range to design, build, and ship entire platforms and products single-handedly, from messy real-world constraints to systems that are live, monitored, and yours to run.

TrainSphere

A marketplace of certified sports coaches, designed, built, and hosted A→Z, solo.

TrainSphere is a two-sided marketplace connecting certified sports coaches with people looking for structured training. Thomas Baudry designed, built, and operates it end to end, from empty repository to a live, monitored, GDPR-compliant service. Coach trust is enforced by verification of credentials, business registration, and identity in the data layer.

Technology

Frontend: Next.js 15 (App Router), React, TypeScript strict
Backend & data: Raw SQL via pg on PostgreSQL (AWS RDS), 60+ versioned migrations
Infrastructure: ECS Fargate, ALB + HTTPS, private VPC, Terraform (eu-west-1)
Delivery: GitHub → CodeBuild → ECR → rolling ECS deploys
Payments: Stripe-ready payment layer (FR-compliant)

How it ships

Every push flows from the repository through CI/CD to a rolling deployment on ECS Fargate. It reaches users in minutes, with a health check gating each release.
