A gambling company. We developed the event offer backend of the company.

Elixir Developer

During the cryptocurrency craze in 2017, I started working for a company that developed a monitoring and management system for cryptocurrency mining datacenters.

Backend Developer

After moving to Spain, I continue working with them in the same business: automatic investments in the ForEx market. One of the big changes was using Elixir for handling the events coming from the market: Yggdrasil was born.

A startup that tried to invest automatically in the Forex market.

Since 2016, I've been coding in Elixir full time every day. I've developed from simple REST APIs to distributed system handling millions of operations per day.

I've open sourced several of the tools I've created to make my life easier. I try to maintain all of them regularly, as I keep using them. The project I'm most proud of is Yggdrasil. It's a distributed agnostic pub/sub that has adapters for RabbitMQ, PostgreSQL, and Redis.

Right now, I'm experimenting with raw SQL queries in PostgreSQL using AyeSQL (based in a clojure library called YeSQL).

This was the first language I've used full time when I started working. I learnt all about OTP and its supervisors and actor model. Though, I don't use it directly anymore, I use several Erlang libraries from Elixir like PropEr (for property testing), ETS and DETS tables, and poolboy (for process pooling).

I've used PostgreSQL for every relational database I've used. I'm familiar with stored procedures (PostgreSQL 11), functions, triggers, domains, and roles.

Right now I'm experimenting with writing the business logic as close as I can in my pet project's database. The idea is to keep the database as consistent as possible while decreasing the amount of queries.

I don't consider myself a PostgreSQL expert, considering the amount of features it has and probably I'm not familiar with, but I'm one of the few that enjoys writing raw SQL.
