Senior NLP & AI Scientist
Fatemeh Rahimi
7+ years shipping production NLP and AI systems — from transformer fine-tuning and RAG pipelines to multi-agent LLM orchestration and document understanding. Currently leading AI development as a Senior NLP Scientist at Pythonic AI.
Featured Projects
Production and research highlights
Multi-agent Support Automation
Pythonic AI · 2023 – present
Designed and built an LLM-powered multi-agent system that autonomously triages and resolves support emails involving routine code and configuration changes. Uses prompt-engineered reasoning chains, tool orchestration, and human-in-the-loop escalation to reduce manual engineering effort.
Production NLP Services
Pythonic AI · 2022 – present
Led end-to-end development and deployment of 3 production NLP services for document understanding. Primary technical owner for one service. Built evaluation pipelines to measure model quality and business impact across releases.
Biomedical NLP Research
Imagia · 2020 – 2022
Researched and built NLP pipelines for clinical report analysis — including de-identification, named entity recognition, and measurement extraction. Applied transformer-based models (BioBERT, ClinicalBERT) to real-world hospital data.
MTLV: Multi-task Learning Library
Dalhousie University · 2020 – 2021
CLI library for exploring four multi-task learning architectures with pre-trained language models. Proposed a novel task-clustering approach that improved cross-task transfer. Published at ACM DocEng-2021; served as M.Sc. thesis.
Open Source
Contributions to public projects
Added four new tools to this MCP server for Microsoft 365 — create, create child, rename, and delete mail folders via the Microsoft Graph API. Closes a workflow gap where users couldn't set up destination folders before moving messages.
