Profile

Marshall Rasendria Mahendra

Hi, I'm Marshall.

I train machine learning models and then build the full-stack platforms that put them in front of real people. Currently an Information Systems undergraduate at Telkom University, currently interning as an AI Engineer, and permanently curious.

In the past 6 months I shipped 6+ end-to-end products, reached the finalist stage in 3 national hackathons, and collected 5 professional certifications from Google, IBM, Microsoft, and HackerRank. I like my evaluation leakage-free, my APIs documented, and my coffee unsupervised.

This whole site is one big document. Go ahead, switch to Editing mode and mess with it. It resets when you refresh, just like my sleep schedule.

Machine Learning Engineer

HUMIC Engineering Research Center · Internship

April 2026 - Present · Telkom University

Medical imaging research on mammography classification, from literature review to a published IEEE paper.

  • Conducted a systematic literature review across IEEE, Scopus, and Google Scholar, exposing that many 98 to 99 percent accuracy claims come from patient-level data leakage.
  • Built leakage-free PyTorch pipelines on CBIS-DDSM and trained 6 architectures, from EfficientNet-B3 and ConvNeXt to a CBAM hybrid-fusion network and Mammo-CLIP, across 12+ controlled experiments.
  • Raised AUC by about 6 points with clinical-metadata fusion (0.80 to 0.86) and first-authored a 6-page IEEE conference paper.
