WORK EXPERIENCE

01/2021 - Present, Remote
Freelancing has given me opportunities to work on a variety of real-world problems, so I've had the opportunity to face them and
learn from them.
Migrating a local application to the AWS cloud. I decoupled it and transformed it into a fully serverless application
with zero cost and database query optimization.
Mentoring the development of an application architecture, as well as which technologies to use, data flow,
relationship and decoupling between components, how to modify the project without causing collateral damage,
using clean code and clean architecture with unit and integration tests. As well as how to use emotional
intelligence for leadership in their team.
Automating the generation of a meeting attendance report during the pandemic period, with integration to excel
and software to mute and unmute the speaker's microphone.
Integrating a payment service with an API, which communicates with different contexts within a company using
universal language, entities, value objects, DTOs, domain events, and design patterns.
Developing a Web Scraper to provide data to a bot to publish discounts on a discord server. When a member of the
group clicked on the bot's ad, he was marked as having found the discount through the bot and thus was fitted into a
type of persona based on which type of ad he clicked on.
