Marlon Gemerts

The most credible bio in the batch: a Suriname-based MSc electrical engineer specializing in DSP and a part-time PTC lecturer. On GitHub, though, the data-engineer label is barely supported: 3 public repos (2 original), Jupyter-only, zero stars, zero followers, and no commits in the past year on a young 3.6-year-old account. The authorship verdict is "not primary author," and there are no verified external open-source contributions or deployments. This looks like an academic exploring notebooks rather than a practicing ML engineer. The domain expertise (signal processing, teaching) is real and notable, but production data/ML capability is not demonstrated by the public repositories.
