Alex Fernandez

While I have been employed full-time most of the time since 2012, I have kept taking freelance engagements, since they help me stay sharp and learn new things. In this capacity I have worked for several large companies, including: Grupo Inditex, M&C Saatchi, TUI Group, and a few other smaller companies.

I worked as CTO of Influencity, a company in the field of influencer marketing. I led a team of talented developers and helped them build the best platform for influencer marketing, using Node.js and React. While there I helped improve the architecture, hired two new engineers (for a total of 6 people) and led the team during a complete revamping of critical modules.

Devo is a thriving Spanish company that collects huge amounts of data and keeps it in a searchable format for our customers. We were in the middle of an impressive international expansion. I faced a lot of exciting technical challenges while working there as a senior software engineer. I worked in the data ingestion team. Our system reached peaks of 3.5 million events per second, which it ingested flawlessly. I made my first contribution to the Node.js core while there: a benchmark demonstrating a performance issue with TLS and short-lived connections. Hopefully not the last! I was telecommuting most of the time, and going to the office one day per week.
