About
Hi, I'm Shubham.
I'm a machine learning engineer with computer-vision roots. Most recently I was a Senior MLE at Meta on Instagram Ads Ranking, where I worked on multimodal LLM ranking features, model distillation, and the eval harnesses that keep all of it honest.
Before Meta, I spent a few years at ZEFR building multimodal search and content-understanding systems, did my M.S. in Statistics at UIUC, and worked across computer-vision roles at Reliance Jio and Pitney Bowes, spanning satellite imagery, building detection, and more.
I firmly believe that specialization is for insects, which is why I keep a few too many interests running at once: technology, startups, education, philosophy, and an unshakeable allegiance to Arsenal.
The path here
-
Senior Machine Learning Engineer
2024–2026Meta · Instagram Ads Ranking
- Built multimodal LLM pipelines generating ad-side ranking features, and post-trained open models (SFT, teacher-student distillation) against custom per-field eval harnesses.
- Shipped a domain-tuned video OCR pipeline reaching near-parity with a frontier VLM at a fraction of the cost.
- First author on a RecSys '26 Industry Track submission on text-on-creative as a ranking modality.
-
Senior Machine Learning Scientist
2021–2024ZEFR
- Built a multimodal semantic search platform over 1B+ image and text embeddings, powering CV/NLP fine-tunes across brand-safety taxonomies.
- Fine-tuned CLIP/ViT models and built a vector-search active-learning loop. Invited speaker at the Snap ML group (2023).
