About Julien

I have been developing complete Web3 projects since 2020: Solidity smart contracts, NodeJS APIs, React Frontends, and serverless hosting on AWS.

I have had numerous roles and positions in the IT field since 2004: developer, project manager, scrum master, agile/tech coach, architect, data scientist, and CTO in several startups and groups that have experienced strong growth and are now French or European leaders in their fields.

CEO/CTO of a company offering on-demand CTO services since April 2018 for SMEs/startups/large corporations.

As an on-demand CTO, I help organizations accelerate their innovations, particularly through the use of AWS or GCP Cloud and my skills: AWS for over 12 years, Magento for over 10 years, Node.js since its launch, serverless and microservices for 6 years, Python and BI for 3 years, scrum/kanban for over 10 years...

I can assist you with architecture, design, creating a boilerplate, or the operational and human support necessary to help you build and maintain your services.

Some examples of the stacks I use:
- Dev: Node.js, Python, PHP, Shell, LUA, C#, Vue.js, ...
- IDE depending on the languages: Visual Code, PyCharm, WebStorm, XCode, Jupyter, etc... with intensive use of the debugger in each language
- DevOps: Terraform, Docker, Serverless, GitLab, Jira, Git, Jenkins, CodeCommit
- AWS Cloud: EC2, ECS, ECR, S3, DynamoDB, Lambda, Fargate, Glue, Athena, Rekognition, RDS, IoT, ...
- SQL databases (Oracle, Mysql, PostGreSQL, AWS Redshift, ...) and NoSQL (Redis, Elastic Search, Splunk, Mongodb, etc), Kafka, NiFi, Spark Streaming, Storm, Zookeeper and associated Cloud services...
- Data Visualization: Tableau, d3.js, matplot, ...
