Platform Engineer / Grafana (GO and TS) developer / Helm maintener

Comwork.io

Designing a DaaS (deployment as a service) platform : cloud.comwork.io. The main purpose is to accelerate the deployment providing a PaaS experience with a nice frontend GUI but also giving access to IaC gitops repositories automatically generated with ansible/jinja or helm templates you can update in order to trigger pipelines.

It's also supporting FaaS feature to deploy directly serverless functions in an agnostic way.

You'll find more details on our documentation : https://docs.cloud.comwork.io

And we got some demo on our YouTube channel: https://www.youtube.com/@comworkio

Technologies : Python FastAPI, Pulumi, Go, React, PostgreSQL, Redis, NATs.

Compatibility : GCP, AWS, Scaleway, OVH, Cloudflare, private cloud using openstack. The platform is build using driver/adapter pattern so we can adapt to every type of infrastructure (each cloud platform providing an IaaS api can be handled if we develop a proper driver).

Cwcloud lead platform engineer

Founder, CEO of the French division since 2018 and CTO.

It was and still is an IT services company which help customers to develop, ship in production, scale in the cloud their public applications.

Leading the teams with the following technologies:

Backend dev : design and development of distributed web applications using Restful API or asynchronous worker (using Kafka, Pulsar, NATs, redis pubsub, etc), SQL and NoSQL or hyper distributed database (PostgreSQL, MongoDB, Cassandra, Redis, Elasticsearch, InfluxDB, etc). Programming languages : Java (Springboot, Vert.x, Quarkus, Micronaut), Python (Flask, FastAPI) and Go.

Frontend dev : React, Angular, Vue

SRE / Devops : public or private cloud provisioning using Terraform/Terragrunt on GCP, AWS, Scaleway or OVHCloud. Kubernetes gitops deployment using ArgoCD and Helm, classical compute templating and deployment using ansible, observability using Elasticstack (Elasticsearch, Kibana, etc) or Prometheus, Grafana, Loki, Victoria Metrics.

GCP and serverless : GKE with knative, cloudrun, cloud function, etc (we also can handle the equivalent using AWS).

Chief Technical Officer

VeggiePi

VeggiePI is a project that push aquaponic and hydroponic systems and other smart agriculture projects to the next level. Based on various IoT sensors and actuators, cloud native, bigdata and machine learning.

Rebuild and packaging of diverse componant such as Elasticsearch and Kibana for ARM32 using docker/OCI containers. Python and C development also packaged as docker images optimized for ARM microships and deployed in a gitops way using gitlab-ci.

I joined the French Post's Digital Hub project (a.k.a "Le Hub Numérique de La Poste") as technical leader and SRE/DevOps consultant within the Docaposte IOT division.

It's an universal platform for pairing IOT devices, getting a summary of the data reported by those devices on a dashboard and making them communicate with each other using configurable scenarios (pretty close to serverless functions) and services. This platform can be used both for companies with a business portal and restful APIs and for particular. Lots of public administrations and companies are using it for accelerate their development like a BaaS (backend as a service) and bring more value to their own services using the postman's tour and some devices.

Here's a non-exhaustive list of personal contributions to this project:
- Implementation of a reactive microservice architecture based on Docker, Kafka, Java, Vert.x and Hazelcast
- Implementation of dedicated monitoring instances based on Docker, Nginx, Letsencrypt, ElasticStack (Elasticsearch + Kibana) and Kafka
- Establishment of technical supervision based on collectd, Kafka, Elasticsearch and Grafana
- Synchronization of Elasticsearch clusters on two datacenters via Kafka
- CI / CD: Automation of feature delivery via gitlab-ci and docker pipelines with validation steps and tests using maven or npm or tox
- Automation of the deployment of our infrastructure with Terraform, Puppet, Ansible
- Implementation and maintenance of the exposure of our applications: reverse proxies (apache and nginx), load balencers (haproxy), api gateway (tyk), https certificates with letsencrypt
- Numerous backend features carried out within the features teams whether it is Restfull APIs based on Spring, Springboot or reactive microservices with Vert.x and Kafka and Cassandra, Redis and Elasticsearch as NoSQL databases
- Technical supervision of backend developer teams in Paris as well as in Tunis depending on the period
