Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
About MetalBlueberry
I’m a passionate developer with experience in the world of BigData and Machine Learning.
I feel comfortable working with Python and Go, and I have no problem understanding other programming languages. I know how to use Docker and most of the time, I deploy applications inside docker containers.
I would like to become a senior Go developer and I’m investing personal time to keep moving in that direction.
I’m always looking for new challenges and constantly learning new things.

Technical background
During my career, I’ve been involved in several big data-related activities. ranging from data acquisition to reporting. The role could be described as a Data Engineer1.
I’m familiar with the following technology stack related to IoT
- Acquisition: Arduino/ Raspberry Pi
- Transport: MQTT, HTTPS, TCP/UDP
- Processing: Python Pandas
- Formats: Parquet, CSV, JSON, XML…
- Storage: S3, PostgreSQL, MongoDB…
- Analysis: SQL, Python Pandas, Jupyter Notebook
- Reporting: REST API, Plotly Dash, Power BI
As a developer, the following is a list of technologies, tools, frameworks… that I’m familiar with, sorted by how comfortable I feel using them. A higher position means more comfortable.

Best Practices
I put a lot of effort into writing high quality code. This includes testing, CI/CD pipelines, documentation, and code best practices.
Soft Skills
I’ve attended several workshops by Enric Lladó related to communication and leadership where I’ve learned how to communicate efficiently and how to be a good leader. I enjoy helping others to grow and the tools provided by Enric have been really useful in this task.
I have been in the role of a Tech Lead2 in a team with 6 members and I enjoyed it a lot.
I have no problem speaking in public and I’ve been doing workshops, talks, and courses in front of many people since the university. I love sharing knowledge.
I have been working with people in other countries like China and India and I know what it means to have a different time zone and customs.
I consider myself a person that does things with passion and with a lot of patience.
I speak English fluently and Spanish. I tried to learn Japanese a few years ago, but failed.
I don’t hate Mondays. I like to read the documentation and I always read the instructions before using any new device. But I have to admit that I almost never read “Terms and conditions”.
If you want to learn more about how I came to be what I am today, you can read the long story or the F.A.Q.

Data Engineers are the data professionals who prepare the “big data” infrastructure to be analyzed by Data Scientists. They are software engineers who design, build, integrate data from various resources, and manage big data. Then, they write complex queries on that, make sure it is easily accessible, works smoothly, and their goal is optimizing the performance of their company’s big data ecosystem. ↩︎

Tech Lead is a software engineer responsible for leading a team and alignment of the technical direction. Providing a strong technical direction involves establishing a technical vision, resolving technical disagreements and managing the technical quality of team deliverables. Effective technical leadership ensures the team uses appropriate engineering practices (such as CD or automated testing), invests in continual improvements to tooling or technical debt, and that the system evolves to meet its changing needs and environment. ↩︎
