Electrical Engineer

Hey everyone 👋🏻

I'm a multi-passionate Data and Cloud Engineer who fancies GCP and the cloud in general. You can check my expertise in detail on my experiences, certifications and projects!

I'm a Data Engineer with over 2 years of experience. I transitioned into the data field from an Electrical Engineering background of over 7 years of experience, where I had to artificially implement data-driven decisions and tools in my day-to-day job. I find it fascinating how Engineering is the same thing, you build stuff with all the knowledge and tools you gathered along the way, but instead of building electrical substations, I now build data pipelines. 🏗️

Here are a few ways I like to spend my time...

- 1:1 calls with aspiring data engineers and analysts.
- Supporting the data community on LinkedIn.
- Doing data engineering and analytics projects involving all the cloud tools I can get.
- Oh I also teach electric guitar and music theory in general! 🎸

In my spare time, I like working on my local church with my music skills and teaching, making some juicy burgers (I do like them burgers), and learning all the nerdy/useless stuff on YouTube!

Want to chat about anything I said above (including music)?

Feel free to shoot me a DM. 😉
