Freelancer profile translated to English.
Back to original languageAbout Grégory
With 20 years of experience in software publishing as an engineer or technical leader, I am an expert in Java EE, Spring, React, Javascript technologies and agile methodologies.
I had the opportunity to create products for the world's 500 wealthiest individuals (Crédit Agricole, Intuit, IQVIA) as well as for start-ups (KidPool, Ipso Facto) as CTO or software architect.
A graduate of the Conservatoire des Arts et Métiers in software engineering, my areas of intervention are:
- Analysis, Design, and implementation of Web applications (PWA, SAP) in Java, Spring, ReactJs, Redux on monolithic or micro-services architectures deployed on the cloud (AWS, GCP) via Kubernetes.
- Integration with external products via Web Services (REST, SOAP) or communication buses (JMS, Kafka, RabbitMQ)
- Collection, processing, and consolidation of large volumes of data (Scraping, Elasticsearch, Spring Batch, MongoDb, Big Data, Machine Learning)
- Implementation of continuous integration chains to automate deployments and tests (creation of CI/CD pipelines under bitbucket, gitlab, jenkins).
- Facilitation of workshops on agile methods and good coding practices.
- Code audit and refactoring
- Realization of Proof Of Concepts (POC) or Minimal Value Products (MVP)
Having grown from product failures where the customer was not placed at the center of development, I advocate for:
1. An iterative and incremental approach throughout the software development cycle. Ambassador of agile methodologies (SCRUM, Lean, XP).
2. Great empathy towards customers. Observing their behavior when using an MVP or conducting data-driven development are keys to success in producing usable and used tools.
3. The creation of a modern software factory.

- INTUITEngineering ManagerSOFTWARE PUBLISHINGAugust 2016 - September 2018 (2 years)Paris, FranceWhen I joined Intuit as Software Engineering Leader for QuickBooks (QBO) in August 2016, QBO was struggling with 1500 subscribers in France despite being the leading small-business accounting Saas in the US, Canada and UK. Technically, QBO had a monolithic architecture (more than 4 million lines of code), no Automated Integration testing and difficult customization for regional teams. It took 30 days to release any small change to production.Over the next 24 months, I:- hired and mentored a multicultural SCRUM team of 7- increased sprint velocity by 4X and velocity per engineer by 80%- decreased release cycle time from 30 days to 5 days by moving to micro-service architecture, allowing for rapid customer feedback and issue-resolution- built an automated testing platform, reducing testing time by 65%After 2 years, those key achievements has paid off: accelerating subscriber growth from 2K to 8K in 1 year; core-customer NPS from -10 to +30; and a great engineering team.
