About Sefer

I am a results-oriented Data Engineer working as freelance with over 7 years of experience in developing, testing, and maintaining software for data acquisition purposes on both Edge and Cloud platforms.

The combination of consulting under high workload and internal product development has equipped me with the skills to quickly build PoC's, diagnose, fix, and prevent problems from reoccurring, but also thinking in a structural way about how to improve a product.
