## bio
Hi, my name is Paul. I\'m a DevOps Engineer with more than 5 years of experience creating and managing web
applications and cloud computing infrastructures. I\'m acquainted with AWS and its Terraform provider, having used the
latter in order to maintain solid code-bases (Infrastructure as Code), ensuring rapid deployment, iteration,
redundancy and fallback of infrastructure. From endpoints (Gateway API) to load balancers (ELB) and auto-scaling (ASG),
to serverless apps (using AWS Lambda), or Docker based tasks (ECS), I got you covered! AWS services I\'ve worked with
and configured, include (but are not limited to): EC2, ECS (with and without Fargate), CloudWatch, Lambda, Gateway API,
IAM (authentication/authorization for mid-sized teams), IoT, S3\.\.\. I\'ve also been in charge of deploying and
managing Jenkins instances, for running CI/CD jobs, combining both in-house and remote servers (Jenkins EC2 plugin).

Besides infra., I\'m an experienced full-stack web developer, knowing my way around popular Python and
JavaScript frameworks (Django, Twisted, Flask, React, Vue). I also enjoy working on lower-level native applications, be
it in Python (for wrappers and projects requiring quick iteration) and/or C, C++ and Haskell, for more
performance-critical components.

I know my way around the Linux operating system, having done a fair deal of shell scripting and usual management
tasks. During my time in the robotics industry, I\'ve had the chance to work on Linux kernel modifications (to aid in
hardware emulation) using C. I\'ve also worked extensively on debian packaging (.deb files) and maintaining of APT
repositories (Nexus) for first-party packages (targeting Ubuntu and Debian).

On a more personal note, I feel great curiosity towards subjects like Genetic Programming and Artificial Intelligence,
and love playing with these topics in my spare time. Below I list a couple of hobby projects which explore these
subjects, along others like Artificial Life, Reinforcement Learning and Neuroevolution.
