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.
My native language is French 🇫🇷, but I also speak English 🇬🇧 (almost fluently when writing, but intermediate when speaking). I also know the very basics of German 🇩🇪.
Feel free to contact me to discuss your needs.
Expertise
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.
DevOps
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.
