I’ve been doing a lot of blogging lately. You might be tired of hearing me complain about my work, but I feel like this is helping me—like a mantra—to find balance and move on. It’s been a good ride: In 2018, I started in data by maintaining a data platform based on Hive (Azure HDInsight at the time, coordinated with Azure Batch and webjobs), and then I helped maintain the migration to Databricks. At that time, I was mostly an ETL developer. I learned Scala (and fell in love with it) and wrote a lot of complex business logic. Read more

I quit my job after the trial period because I didn’t find what I expected from a startup, nor did I get the benefits of an established company. It was a dealbreaker. However, I will remain for an extra 3 months since there is a project I want to be involved in. I’ve been granted more flexibility, and I want to use this time to prepare myself for what’s next.

Lately I’m not exactly enjoying my job. Snowflake step curve from a data engineer perspective is really hard. Yesterday my boss asked me to test the Snowflake integrated MCP from Cursor. He’d been looking into Snowflake OAuth access, so I went to check the resources. Once again—as of January 27th, 2026—the Terraform resource for this still doesn’t exist (though the data source does, for some reason). For connecting to snowflake you need to define a security integration. Read more

I switched jobs all over again. I’m working in a data company called Shalion, where we provide insights about retail products online. If you’re brave enough to handle Snowflake’s quirks, we’re hiring… I’m working on revamping our permission grant system from permifrost to a terraform managed approach. We also decided to embrace a 2 layer permission grant, using Access Roles (AR) and Functional Roles (FR). The former has access to the resources with the typical permissions (SELECT, USAGE, CREATE)…, while the latter is the one that we assign to people and just groups access roles. Read more

2025 ha sido un año bastante loco. Pasé la mayor parte del año sentando las bases de una startup en el mundo de la seguridad, haciendo frontend, backend, mucho devops y… poco data. Me pilló de lleno la era de la AI y como siempre, el campo ajeno es más verde. Viví la burbuja de v0 y mi trabajo respecto a este, fue bastante miserable. El proyecto a medida que crecía dejaba de ser funcional. Un cambio manual que arreglase el mismo era incompatible. Read more

For the past seven years, I worked in data, and I have mixed feelings about it. I still believe data is the most important part of any app, but it’s meaningless without the app itself. Now that I’m working at a startup, I’ve decided to focus on building things. To start, I revisited one of my older projects: a PDF parser about professor designations in the Canary Islands, where one of my best friends works as a teacher. Read more

As my company undergoes layoffs, I’m back on the job hunt. While I’m in the field of data, I often find myself missing the hands-on experience that comes from personal projects. I realized that I’m not practicing all the skills I need. During a recent interview, I was asked about my experience with sending reports via email—something I hadn’t done in a few years. That got me thinking: could I turn this into a pet project? Read more

Over the years, I’ve been using MacOS at work and Ubuntu at home for my development tasks. However, my Lenovo P1 Gen 3 laptop didn’t work well with Linux, leading to frequent issues with the camera and graphics (screen flickering, I’m looking at you, and it hurts). I’ve triend Windows Subsystem for Linux (WSL) but it was quite bad to be honest. But as I’ve heard of WSL2 and WSLg, I decided to give it another shot. Read more
