Who am I

Hi, 👋

I am Jérémy Goutin, a freelance software developer from France. 🇫🇷

I’m currently working as a consultant while also being an open-source contributor.

As a consultant, I am available to help with your projects with my expertise.

As an open source contributor, I am working on both personal and third-party projects. For more information, take a look at my GitHub profile.

TL;DR: I am mainly a Python software developer, an AWS cloud architect, and a DevOps.

Here is a more detailed description of my expertise:

Software development

Python has been my main language since the start, and I have expertise in it.

I was the software architect or lead developer of various projects and have software design and architecture skills.

My aim is to build maintainable and high-quality software.

I built web backends and API designs using FastAPI and SQLAlchemy (with PostgreSQL).

Furthermore, I occasionally worked on desktop applications with Qt.

Cloud infrastructure

I built the cloud architecture for projects using AWS.

I have a particular experience with securing AWS (least privileged IAM policies, VPC firewall, etc.) and successfully passed an external security audit.

I built both for serverless applications (using Lambda, DynamoDB, Cloudfront, etc.) and more classical applications (using EC2, VPC, Aurora/RDS, etc.)

My experience also includes various other AWS services like S3, SQS, SNS, SES, Route53, Cognito, ECS, and more.

As much as possible, I manage the cloud using infrastructure as code with Terraform.

Furthermore, I also have some experience with Microsoft Azure (Including Microsoft 365 administration), OpenStack, and Alibaba Cloud.


I have solid experience with CI/CD pipelines, and I am able to fully automate them from testing to deployment in cloud environments with GitHub Actions and Azure Pipeline.

System administration

Fedora has been my main OS for years. I also commonly use CentOS, Ubuntu, Debian, and Alpine Linux (in containers).

I have experience building Linux server configurations with Ansible and Docker.

Likewise, I have some experience and a particular interest in Linux “hardening” and security.

Furthermore, I also use Pfsense and TrueNAS.

I also have experience in Microsoft Windows (almost all versions, but not as a server).

Data analytic

My initial formation was scientific, and I switched to software development by building data analytic tools for optical engineers and for automating test benches.

I have experience with Numpy, Scipy, Pandas, Matplotlib, Cython, and the Python scientific stack in general.
