I love working with Golang. I use technologies like Kubernetes, gRPC (so also Protocol Buffers), and PostgreSQL. I use Docker, Git, and Linux all the time. I do Continuous Integration with GitHub Actions.

I'm also interested in learning and working with Kafka, Redis, Elasticsearch, ArgoCD, and even a little bit on the frontend with Next.js (React) or Nuxt.js (Vue). I'm passionate about programming, so I'm continuously learning new things very fast and then applying them.

I strive to make the software the best, feasible way, including following best practices. I'm pragmatic but also a perfectionist whenever that makes sense.

I'm highly focused and self-motivated to learn and to achieve objectives. I have owned a few relatively successful, very small businesses where I did everything, from the software development to the marketing campaigns. I learned and applied a lot of different concepts and technologies on the fly.

Owner/Software Developer

Carta Isapre Abogados May 2018 - August 2019

A legal group I created with 3 lawyers to help Chilean people solve legal cases related to health insurance companies.

Owner/Software Developer

Dofus Alive May 2017 - May 2018

A private, unofficial server of Dofus 1 (a version that's older than Dofus Retro).

I acquired more than 1,500 paying customers, totaling 3,000+ sales.
I achieved a CTR of 6.46%, a Conversion Rate of 11.95%, and a ROI of ~1,200% with my main marketing campaign on Facebook Ads.
I got my business idea validated by more than 200 potential customers who responded to my survey through Google Forms, then many of them became paying customers from my email campaign on MailChimp.
I modified the server (written in Java) and the MySQL database to meet the business' requirements.
I wrote an updater for the client, in Python.
I was running the backend on a Linux virtual machine but then I migrated the server as a Deployment and the database as a StatefulSet on my Kubernetes cluster.
