About

Hi, I’m Maxwell — a Principal Engineer at HTC DeepQ. I build machine learning systems at the intersection of natural language processing and computer vision. Recently, I’ve focused on LLM‑based products for data extraction, clinical chatbots, and medical‑report understanding. I also lead a team of engineers. Previously, I was a machine learning researcher in the Computational Imaging Lab at Sheba Medical Center (Newsweek top‑10 worldwide).

I hold an M.Sc. in Electrical & Electronic Engineering from Tel Aviv University, advised by Prof. Nahum Kiryati and Dr. Arnaldo Mayer. My work spans LLMs, outlier detection for CV/NLP, semi‑supervised learning via knowledge distillation, and flow‑based generative models.

Timeline

  1. Principal Engineer — HTC DeepQ

    Apr 2025–Present

    • Architected hybrid‑reasoning LLMs with reinforcement‑learning post‑training, achieving state‑of‑the‑art accuracy on complex clinical‑language tasks.
    • Deployed a production pipeline that processes ~200,000 nursing reports each month—validated by nursing professionals—while outperforming GPT‑4o in accuracy, running 30× faster, and delivering 5,000× lower cost.
    • Built organ‑specific summarizers for prostate and breast‑cancer cases, fusing long‑form, multi‑domain clinical data (lab, pathology, imaging, narrative notes) into concise, physician‑validated synopses.
    • Lead a team of engineers and interns exploring data‑extraction and information‑validation techniques.
    • Partner daily with full‑stack engineers, product managers, and physicians to deliver production‑grade AI solutions.
  2. Senior Engineer — HTC DeepQ

    Sept 2021–June 2025

    • Developed custom LLM models for clients in healthcare, government, media, and legal sectors.
    • In charge of Large Language Model (LLM) research & development (pre‑training, fine‑tuning, evaluation, and deployment).
    • Owner of DeepQ AI Platform v2 (feature development and maintenance).
    • Invented internal data cleaning tools for vision and language data management applications.
    • Developed specialized CAD model for simultaneous lung nodule classification and localization (featured model in AI Platform v2.3).
    • Authored 2 papers and 6 patents.
  3. Machine Learning Researcher — Sheba Medical Center

    Apr 2018–Sept 2020

    • Led the development of a COVID‑19 lung CT screening system in Sheba [underwent pilot tests]
    • Developed an automated knee MRI diagnosis algorithm suitable for triage (tested and verified by the Head Radiologist of the MSK Department)
    • Implemented a text analytics algorithm for labeling breast MRI reports written in Hebrew and English
