README 

        
Hi! My name is Maël ([prononciation](https://maelvls.dev/media/mael-pronounciation.mp4)). I am a software engineer living in Toulouse (France). I like to promote psychological safety through transparency, empathy and kindness. I do infrastructure software around networking and containers. After multiple technically successful projects and the realization that no user was using them, I started shifting from building software to helping out figure whether building or not building, and I discovered that "product management" is the role that fits this description.



You may read about me digging into networking, Go development, and Kubernetes [on my blog](https://maelvls.dev/).

🔰 Curriculum & contact information



### System Software Engineer at CyberArk _(2021–present)_



I joined the [cert-manager](https://github.com/jetstack/cert-manager) team at [Jetstack](https://jetstack.io/about). Jetstack was acquired by Venafi in 2021, which was acquired by CyberArk in 2024.



As part of the cert-manager core team, I mentored new contributors into merging their first pull request. During my mandate as a release lead of cert-manager, I worked on moving away from Bazel in order to reduce the friction new contributors were feeling when getting started. I worked with sig-network on the Gateway API integration in cert-manager, as well as on making the ingress resource documentation clearer for ingress controller implementors and ingress users alike.



Along with the open-source work, I contributed to Jetstack's enterprise offering, and led an effort towards customer success via lean product practices.

  

### System Software Engineer at Ori Industries _(2019–2020)_



As a Software Engineer at Ori Industries, my main focus was to develop an edge-aware version of Cloud Foundry. Telcos would use this infrastructure platform to leverage its low-latency last-mile 5G network. With this platform, they can sell compute time to developers with a network latency of 1-2 ms, acting as a public cloud provider of their own.



As an individual contributor, I helped shape the Kubernetes components that would make up the Ori infrastructure platform. Among others, my team built a Kubernetes native API for spinning up VMs on AWS, GCP, and OpenStack and bootstrap them into Kubernetes clusters. I also worked on a custom control plane for Envoy (our platform’s data plane) inspired by Istio. I contributed to the company’s initial REST API built-in Go that used a CQRS approach and NATS for the event persistence. My main achievement as an individual contributor has been to become the go-to person anyone would come to regarding Kubernetes controllers as well as for debugging Kubernetes and network-related issues.



After a few months, I stepped up as tech lead in a team of four people. I would run the daily standups, make sure the backlog is in good shape, work with the Product Manager to flesh out stories, point the stories with the team, run a biweekly retro meeting (we ended up working in an uninterrupted sprint). Notable achievements are the “project office hours” I started; the meeting increased the cross-team communication through demos and open discussions about anything more or less related to my team’s project.



Beyond my primary assignment, I also worked with the rest of the company on topics such as



*   Helped grow the remote-first culture thought experiments such as the “wormhole” and by pushing for better video call quality (more than 70% of the company now equipped with proper standalone mics such as the Blue Yeti). A blog post about my experience of remote work is published [here](https://medium.com/@bryony.snelling_26575/mr-remote-working-2c953c121968).

*   I initiated a movement towards transparency across the company that led to a rewrite of the “values” page. We started recording meetings and creating, for each meeting, a shared document with an agenda and collaboratively-written minutes.

*   Contributed to the company knowledge base on various topics such as “the git guide,” “slack etiquette,” and “recording and sharing meetings.”

*   Attended all weekly meetings of [sig-cluster-lifecycle](https://docs.google.com/document/d/1fQNlqsDkvEggWFi51GVxOglL2P1Bvo2JhZlMhm2d-Co/edit#) to keep the company up to date with upstream developments as well as advocate for our solution; contributions: [kubernetes\-sigs/kind](https://github.com/kubernetes-sigs/kind/pulls?q=author%3Amaelvls), [kubernetes\-sigs/cluster-api](https://github.com/kubernetes-sigs/cluster-api/pulls?q=author%3Amaelvls+)

*   I helped develop a self-learning program where each engineer spends 20% of their time training on various topics. I authored a couple of [blog posts](https://maelvls.dev/) and proposed learning topics engineers would pick during their training (mainly around Kubernetes controllers, networking, and Linux-y things).

*   I authored the technical test given to applicants and was part of the technical interviews.

*   I wrote multiple internal kubectl plugins for interacting with our custom resources and a tool for monitoring and removing unused VMs on OpenStack, AWS, and GCP.

*   I authored [ngroker](https://github.com/maelvls/ngroker), a tool we used at Ori for running a shared ssh session without the hassle of exchanging ssh keys (using Github usernames).

*   I wrote an interactive [ChatOps bot](https://github.com/maelvls/gh-actions-chatops) using Github Actions for applying Terraform changes through PRs.



**Tools used**: Go, Kubernetes, Github Actions, Helm, Terraform, AWS, GCP, OpenStack, Agile.



### Fullstack Software Engineer contracted to La Banque Postale _(2019)_



As part of a network operations team, I built a web application meant to become a self-updating repository of IP assignments (as opposed to using Excel sheets), which helps the operations team plan and execute fail-overs.



**Tools used:** Java, Spring Boot, Typescript, Angular 2+, NgRx.



### Systems Software Engineer contracted to Orange _(2018)_



As part of an operations team, I built a Terraform plugin in Go for a private cloud used within Orange (mainly interacting with VMWare vRA 7 APIs). I also worked on the continuous testing and delivery of Docker images used by application teams across the company.



**Tools used:** Go, Terraform, Gitlab CI, Bash, VMWare vRA 7.



## Education



### Ph.D. in Computer Science _(2016–2018)_



I developed [touist](https://github.com/touist/touist), a compiler written in OCaml for a new logic language meant to formalize and solve problems expressed as SAT expressions. The tool is now used to teach logic to first-year students at Université Paul Sabatier in Toulouse and is used by researchers to explore new SAT encodings; see [the thesis](http://thesesups.ups-tlse.fr/4328/1/2019TOU30079.pdf) (in French).



As part of my PhD, I also helped develop a web application serving as a frontend to the compiler written in VueJS and Rust; we deployed it through Docker images built by Travis CI and run using AWS ECS.



**Tools used:** OCaml, Rust, Typescript, AWS ECS, Travis CI.
