antoine jeanselme — Backend Engineer
builder by day, boss-fighter by night.
I design and build backend services and the infrastructure that keeps them up: 4 years of Java, TypeScript and Spring, plus Kotlin and Go, shipped with CI/CD, Kubernetes and Terraform.

backend & cloud infrastructure engineer — shadow studio
2024 — 2026designed the backend architecture and rest apis of a platform that grew to 30,000+ unique users, deployed across cloud and on-premise environments.
- built a robust, automated, high-availability backend running on docker, linux vms and self-hosted infrastructure
- industrialised delivery with ci/cd pipelines for java, typescript, kotlin and go services: faster releases, more reliable deploys
- ran shadow studio as an entrepreneurial project: recruited and managed 3 developers and owned architecture decisions between product and tech
- administered linux environments, networking and observability tooling to keep services up

backend & devops engineer — parallel studio
2022 — 2024built the delivery pipelines and production infrastructure behind under the waves — 2M+ copies sold.
- designed ci/cd tools and pipelines (jenkins, docker, azure) in python, go and c#/.net to automate deploys for a team of 30+ developers
- administered production infrastructure — linux servers, network, storage, cloud and self-hosted backups — with high availability
- developed and maintained the multiplatform delivery pipelines for the game

fullstack developer — open source & community projects
2014 — nowopen source around modern infrastructure, authentication and web3, plus a kubernetes homelab to experiment with.
- a self-hostable sign-in with ethereum auth server (fastify), designed api-first with security in mind
- a web3 plugin for minecraft (kotlin, nest.js) integrating blockchain services and distributed apis
- fixes, features and optimisations contributed to better auth, zerobyte and others
- a kubernetes homelab for automation, infrastructure as code, gitops and cloud-native architectures

I like owning a service end to end: the API, the data model, the pipeline that ships it and the infrastructure that keeps it up. Over 4 years I've designed the backend of a platform that grew to 30,000+ users, and built the delivery pipelines behind Under The Waves, a game that sold 2M+ copies.
It started at 14 with a Minecraft server — Linux, SSH, keeping a machine running for other people — and grew into ShadowAxe, a community I've run for over a decade. Running it as Shadow Studio taught me the other half of the job: recruiting and managing 3 developers, and making architecture calls that balance product and tech.
I write things down (docs and runbooks are part of shipping), I keep learning on my Kubernetes homelab, and I work comfortably in French and English. Off-screen: chess, tennis and the gym.
