HI! I work as a Machine Learning Engineer & Researcher with a focus in NLP, MTL, and RL. I'm the sole MLE at a stealth, pre-launch startup and Founder of LiminalML. On the research side I'm mostly focused on multi-task learning (MTL) within NLP.

Now

Current focus

Working ML Engineer at a stealth, pre-launch startup — sole MLE on a 5-person team.
Building LiminalML — a structured, non-skippable path to ML/SWE interviews across 157+ topics, grounded in the candidate's own resume.
Researching LexiMind — 272M-param encoder-decoder transformer from scratch, MTL across summarization / topic classification / emotion detection. arXiv preprint, EMNLP 2026 target.
