Experience

  • Launch of a New Product Line (Development)

    I've led and developed a new product line that has grown to be an important business unit of the company. The project is live today and it lasted nine months until public launch; it included several iterations and testing phases (internal only with friends, family, and early adopters).

  • Automation of Manual Processes (Development)

    Throughout my career, I've participated in the automation of several manual processes.

    Previously, they took days to weeks and required a person doing time-consuming tasks like printing files, clicking checkboxes, verifying multiple data sources, and so on.

    Step by step, these processes were automated until minimum acceptable work was required to keep these operational.

  • Private Slack Bot (Development)

    This Slack bot is capable of answering common company-wide requests and aggregates data from other sources for easy consumption.

  • Open-source Linter Extension (Development)
    https://github.com/wealthsimple/rubocop-vendor

    After analyzing our codebase, we decided to introduce linters that would check for incorrect usage of our integration partners, suggest the correct approach, and in many cases auto-correct the code.

  • Video Transcoding and Bandwidth Detector (Development)

    While developing a video interviewing platform, we had users all over the world. It became evident that we needed to transcode videos in several quality versions so that we would serve the best video for that user's bandwidth to prevent buffering, poor experiences, and increase the likelihood they can complete their interview.

  • Personal eCommerce Website (Development)
    https://github.com/cabello/django-jobim

    When moving countries, I had to get rid of all my stuff but two boxes of personal belongings. I did that by implementing a custom eCommerce website in Django/MySQL and made it open source.

  • Yahoo! Meme (Development)
