I, Alberto Contreras, apply for upload rights for package(s) cloud-init.

I am applying because:

• I'd like to eliminate delays in getting my work sponsored.
• I'd like to reduce the burden on my sponsors.

Who I am

I am Alberto Contreras. I have a BSc in Mathematics from University of Granada and a MSc in Computer Science from University of Malaga.

Prior to working at Canonical, I did work as a software/scientific engineer during 5 years in the fields of Monte-Carlo simulations, smart cities, reconciliation in banking and digital marketing using technologies as C/C++, Matlab and Python.

I joined Canonical in 2022 as part of the Canonical Public Cloud (CPC) team as a software engineer with focus on a good integration of Ubuntu in Public Clouds, mainly working on Ubuntu Server projects, as cloud-init, ubuntu-pro.

My Ubuntu story

My first contact with Linux was with a mini laptop provided by my school, which as Debian installed. My first contact with Ubuntu was in 2008, when I downloaded an Ubuntu 8.04 ISO and installed in my workstation. I was impressed by the performance, cohesiveness and beauty of the OS. I maintained a dual-boot system with Windows (mainly for gaming and windows-only compatible programs for my studies) during some years.

I used Debian / Ubuntu during my university studies and in an internship I did contributing to Normaliz. My professional career was full of Ubuntu too, either as a target and/or a development systems.

Since I joined Canonical in 2022, I have improved how Ubuntu behaves, adding features, fixing bugs, improving its perfomance and adding documentation. Working mainly in cloud-init upstream and downstream (Ubuntu), and ubuntu-pro.

Things I could do better

Sometimes, while focused on planned features / bug fixes, is hard to find time to work more on code quality / refactorings for cloud-init.

Plans for the future

General

• Improve boot performance.
• Implement cloud-specific ubuntu cloud-init packages to reduce images size.
• Close gaps in AWS multi-NIC auto-configuration.
• Improve cloud-init's code quality, typing, documentation, release process, testing, etc.
• Help more new contributors, either from the community or Canonical, to cloud-init.
• Squash more old bugs.

What I like least in Ubuntu

(Specific to cloud-init) While we have improved and are working on boot performance, I still think it is probably the thing that I most dislike about cloud-init. We will continue working on it in future cycles.
