At ticketea I did mainly backend and APIs development (Python 2/3, Django), including building a high-load checkout service backend. I also Migrated the main website to Python 3, did component rewrites, legacy systems containerization and Continuous Integration workflows setup, and I was a participant in a partial platform migration from AWS (ECS & ECR, SQS, Kinesis) to Google Cloud AppEngine (Docker, Cloud tasks, Pub/Sub).

I led a cross-functional team in charge of building customer-facing services: Web application, public API, mailing and notifications service, user accounts service and Facebook video distribution. I mostly did backend, APIs and Microservices development (Python 3, Flask), and helped taking high scalability architecture and SaaS platform design decisions. We tried to avoid reinventing the wheel by heavily relying on AWS (EC2, ECS, SQS, Kinesis, S3) and third-party services whenever possible. I performed DevOps tasks and was on-call support. Mentoring and recruiting activities.

I also built new features like user groups/companies, an enterprise LDAP connector, and internal tools like a quick rollback feature. Technical outreach and recruiting activities.

Senior Software Engineer at Minijuegos/Miniplay - Feb 2013 - Dec 2013

My work at Minijuegos involved both backend and frontend (JQuery) development. Alongside the CTO, another software engineer and two designers, we did a full visual redesign and code rewrite of the platform, while also adding new features. I built most of an asynchronous job-based user avatar generator, an avatar items store (built as a Single-Page Application) and implemented multiple payment systems. I also built a new internal CMS and wrote some data migration scripts. Mentoring of new hires, technical outreach and recruiting activities.

During my four years at Tuenti I worked both on frontend (vanilla ES3 & ES5, YUI) and Backend development. I helped accomplish multiple website redesigns (1st almost full code rewrite) with focus on high scalability. Some areas I worked on were main website and mobile version development, backoffice and internal tools. My tasks were varied, from maintaining and evolving the mobile website, to building the first mobile apps updates backend and support tools (J2ME, Blackberry), building the first Pages/Groups version (frontend and backend), participating in the chat client full rewrite and inclusion of group chat and new XMPP features (like private photo sharing), user notifications, multi-search, friends importer, migration of in-house CMS to Symfony framework for easier maintenance...
