Software Development Team Lead

Unipart
juillet 2023 - juin 2025
● Role: Owner of the tech stack of all products sitting on top of SAP and for all clients
● Mission: Merge 2 development teams (12 people) with different tech stacks and practices.
Total portfolio 39 apps across AWS, GCP, IBM Cloud
● Implement new ways of working focused on reliability and scalability. Apps were initially
criticised for their poor performance. jMeter helped us figure out where the bottle necks were and the blame was quickly removed from this team, as it showed underlying ABAP code or BASIS infrastructure issues. We collaborated to help them address these issues. Reliability was also poor and hotfixes were the norm (release frequency once per month, often required
2 or 3 hotfixes each time). Unit and integration tests were added.
● Increase maintainability: Ensure all apps are documented properly and can be worked on and
release. Some were not updated often and were dangerously heading towards being
unmaintainable.
● Update apps design and enforce development best practices
● Proof of concepts to support new projects (like SAP BTP and S/4HANA)
● Collaborated much with ABAP and other SAP specific teams to help them implement new
features and take a co-design approach rather than silo, predominant until then.
● Key tech: AWS, GCP, IBM Cloud, Java, Python, Javascript, Gitlab CI/CD, REST APIs, Oracle, PostgreSQL, Redis, SSO
● Key achievements: streamlined practices across 2 very different teams, increased cooperation outside team to release features faster, practically eradicated hotfixes

● Role: Owner of the tech stack. In charge of all clients and unique product
● Mission: Intelematics had a solution in place when I arrived, developed in Australia. But it
didn’t scale to the European market. Collaboratively defined the appropriate strategy with the
founders as a senior leader and implemented it
● Designed event-based microservice architecture for in-car IoT devices with Kafka
● Set up Kafka, wrote first independent microservices with their infrastructure defined as code
(Terraform, Ansible), and built in CI (Gitlab) with code coverage and deployment to AWS
(Kafka, ECS, Elasticsearch, Redis, Cloudwatch, API gateway, ...) and on prem (VMWare)
● Created the whole tech team from scratch to scale by adding more microservices
● Lead implementation across multiple companies of these microservices

● Key achievements: Divided development cost by 2 with microservices and event-based
architecture compared to the Australian solution. Helped acquire many more customers
