TESSAN · Paris, France

Tessan is a very prolific French start-up tackling the challenges of medical personnel scarcity. They develop both the software and the augment cabins for tele-consultation. That is, patients can book a remote session with doctors (generalist or specialists otherwise across France) OR get to a nearby pharmacy, enter a cabin and enjoy the high-tech gadget along the remote experience. I joined the team as a DevOps Engineneer and help with Kubernetes maintenance, tracking production issues pertaning infrastructure (like Redis replication failures) or the monitoring with Datadog. I also worked on securing our remote accesses to the cabins, which is critical in supporting clients in real-time.

Thales Group · Paris, France

Thales is one of the leading engineering company worldwide in many fields, and most certainly in Europe. One of their product is a software to run ground transportation (buses, trains, and more) known as GTS. It is a comprehensive solution that covers everything from planning to access through maintenance and security. I joined the hybrid team of 12 people, working on the video surveillance, to maintain and migrate a legacy VMS (TVS) to 12-FA multi-VMS (ALVEA). +1bn people served daily.

BNP Paribas · Paris, France

Member of the feature team rewriting the Risk-Adjusted Return on Capital (RAROC) platform MVP. I focused on the simulation microservice and leveraged Spring Framework and Domain-Driven Design to develop and test REST services that collect and organize data for the RAROC calculus microservice, and version simulations and their contextual data.

Societe Generale · Paris, France

Societe Generale is a French bank, the largest in Europe, established worldwide. Member of the GTS Alerting team for their private cloud platform. Here are my major contributions to the project: + Re-engineer the Java-based microservice at the core of monitoring, based on Apache Flink with the goal of not repeating logic across the code base + Fix various bugs from v1 logic that caused more than 30 crashes per day in production environments + Design abstractions for Apache Flink data sources, for consistency and reuse across the service + Collect custom metrics sent to Influx DB and build live monitoring graphs with Grafana + Advocate for GitOps-based CI/CD and implement it using on-premise Jenkins, and some Python scripting, across environments & the multi-region cloud + Secured our pipelines & clusters by migrating secrets from Jenkins and Kubernetes secrets to Vault + Developed a Python-based microservice that integrates with the in-house ticketing system, to serve users preferring ticketing for resources monitoring alerts. I used Flask, Open API, OAuth, RabbitMQ, PostgreSQL and SQL Alchemy + Provisioning of “static” resources (PostgreSQL database, InfluxDB, AWS S3 buckets) using Terraform and Ansible As a result, we ingested 14.5 billion metric events daily, crossed with 11.3k monitoring rules (default and user-defined), produced ~26k violations (ACTIVE/INACTIVE) per day and, thanks to anti-flood, ~3k alerts daily. The Grafana boards & Apache Druid aggregated metrics provided insights to fine-tune performance further for Apache Flink within our clusters. Terraform and GitOps CI/CD made deployments a breeze.

Muuv Labs (a Vi company) · Texas, United States

Muuv Labs merged with Vi Labs and is now a Vi company. Their innovation labs help health and wellness companies develop the next generation of products, faster and more affordable than ever before.

Accenture Security · Ebene Cyber City, Mauritius Island

Memority is a French startup which was absorbed by Accenture in 2018 until late 2023. It is also the product they develop: an Identity and Access Management (IAM) both as a Platform as a Service (Paas) & on-premise enterprise software. The multitenant solution featured flexible models, custom IAM workflows with BPMN, permissions & roles delegation, custom UI, in-app scripting, and integration with external tools (client APIs, LDAP, InWebo, SAML, OpenAM). I implemented many features in various microservices, from authentication to data model migration, through developing frontend widgets and integrating them with back office and backend APIs & dataset import and export. I did some CI/CD scripting in Jenkins, managed dependencies with Maven, containerization with Docker, data storage with PostgreSQL and MongoDB, backend with Spring Framework, database schema versioning with Flyway, frontend with Angular, and broker with RabbitMQ. + Memority received ISO27001 certification DevSecOps under SOC and “Les Cas d’Or” 2019 for IoT security. + It powered security around the Internet of Things (IoT) for renowned vehicle constructors + A demo delegated permissions over a flying drone, and the recipient took control right away, in-flight
