Hugo Barrera's CV


I’m a software developer, and have been coding since 1999. I’ve been getting paid for it since since around 2009.

I started out with PHP and Java (I’ve seen things no man should see). I’ve worked a lot with Python over the last decade, and a bit or Ruby (yuck). Also did some tiny hunread-line C programs, but nothing huge. I have done some very small contributions to swaywm, the Wayland compositor I currently use.

Over the last few years, I’ve also done plenty of web (and API) development, VueJS, TypeScript, Django. Since 2013, I’ve also been a maintainer for the pimutils tools, which I’m currently considering rewriting in go.

Over the last year or two, I’ve been playing around a lot with golang and Rust, and I’m currently using golang at work too.

I’ve been working on various open source projects lately. clipmon is a Wayland clipboard monitor. The idea is not show a brief notification when an application pastes, so catch misbehaving applications that are snooping clipboard selections. It’s honestly semi-parked because I keep finding bugs in how other applications handle the clipbaord, and the current [experimental] wayland API for clipboard manager lends itself to race conditions.

I’d love to jump into working with all these kind of activities as a day-job, rather than just something I can only do a couple of hours a week on my spare time, and I’m very certain I’d be able to contribute a lot to the general Linux Desktop ecosystem.

Finally, I’ve also worked plenty with containers, docker, podman, packaged applications for Flatpak (I actually contribute on FlatHub community-maintained packages too). You might have guessed that I know how to use Git, and have worked setting up CI and CD pipelines dozens of times.

Oh, and, also I’m a fan of automated testing. Maybe it’s because I’m a really good developer who writes good tests. Maaaybe I’m way to lazy to test everything manually all the time. Who knows.

Professional Experience

Senior Software Engineer @ ProctorExam
Oct 2020 - Current, Amsterdam, NL
I’ve been designing and implementing applications to handle live management of video streams. I’ve used AWS Lambda to implement multiple event-based micro-services, as well as contributed to improving our pipeline, migrating to GitLab CI, and improving developer experience through automation and standardisation.
Tech: Golang, AWS Lambda, TypeScript, Ruby on Rails, Docker, Docker Compose, PostgreSQL, GitLab CI, JavaScript, React
Tech Lead @ Tiqets
Jan 2020 - Oct 2020, Amsterdam, NL

Tiqets was my first experience as a Tech Lead at a larger company. While somewhat intimidated by the challenge at first, I quickly realised that the things that are expected of a Tech Lead are exactly those things which I’d been leaning towards in recent years.

As well as providing higher level problem solving, I pushed to improve our development workflow and deployment practices. Our team spearheaded a migration to a cleaner, simpler CI+CD platform, which we then gradually adopted company-wide.

I also contributed to coordinating better system design and greater inter-team collaboration.

Tech: Python, Flask, Django, Docker, Docker Compose, Celery, PostgreSQL, GitLab CI, Metabase
Senior Backend Engineer @ 3D Hubs
Apr 2019 - Jan 2020, Amsterdam, NL

My responsibilities at 3D Hubs included interviewing and mentoring new joiners, improving our onboarding, and assiting newcomers in understanding how our systems work and our development workflows.

I presented proposals on improving our work practices (eg: git flow, automated migration management, etc.). I helped deliver solid solutions for eliminating accumulated technical debt and led the team to reach a consensus on how we’d address each of these.

Finally, I contributed to documenting how our systems work, including some of those non-obvious internals that all large systems tend to grow, which helped fellow developers have a clearer vision of different moving parts and how they fit together.

Tech: Python, Flask, Docker, Docker Compose, Celery, PostgreSQL
Senior Engineer @ Medallia
Feb 2018 - Apr 2019, Ciudad Autónoma de Buenos Aires, AR

I was accountable for consistently shipping quality features that added value to the product while minimizing debt. It was also my responsibility to improve team’s effectiveness by identifying knowledge, tools, and process gaps in team and partnering with management to address them.

I worked on several smaller projects in Python, Flask, Django, which ran on docker both in our own DCs and AWS. My role required me to identify needs of consumers and then design and implement our systems based on these needs.

Python Engineer @ Shiftgig
Feb 2017 - Feb 2018, Ciudad Autónoma de Buenos Aires, AR
My responsibilities included collaborating with cross-funcional teams to deliver product features and enhancements, writing unit tests for automated testing and implementation of data models in relational and non-relational stores.
Senior Developer & Architect @ ShipNow
Jan 2016 - Sep 2016, Ciudad Autónoma de Buenos Aires, AR

My responsibilities have varied from simple development, to defining workflows, deployment techniques, and selecting the appropriate tools, services and environments for the team, though all final decisions were made as a team.

I worked on integrating with various external services, including payment providers, shipping providers, and other third party systems.

Software Engineer @ Freelance

I worked as a freelance developer for several companies and smaller projects (many of these solo projects).

  • Developed and maintained multiple Django-based web applications and REST APIs.
  • Performed python2->python3 migration for existing codebases.
  • Worked as full stack developer and admin for django-based applications hosted at AWS.

I enjoyed not only programming at these positions, but also understanding the exact problems my clients had, and figuring out the best solutions for their specific needs.
