Georgi Mullassery

A Martech-focused Solution Architect working at the intersection of data engineering, martech workflows, and AI engineering — building high-performance, production-grade systems that solve real-world challenges at scale.

Open Source contributions on GitHub:

- StatGuard (https://github.com/mullassery/statguard) — A data quality, validation, and drift monitoring engine — 10–20× faster than Great Expectations and WhyLogs, with a clean Python API and streaming support built for production pipelines.

- ClusterAudienceKit (https://github.com/Mullassery/ClusterAudienceKit) — A high-performance customer segmentation engine built in Rust with Python bindings, delivering 10–25× improvements over scikit-learn for RFM analysis, clustering, and real-time audience updates.

- StreamXL (https://github.com/mullassery/streamxl) — A streaming XLSX reader for Python powered by Rust. Reads large Excel files row-by-row at cthan openpyxl — with PyO3 bindings andfull pip/uv support.
I design systems where data flows cleanly, audiences are understood deeply, and AI does the heavy lifting — so marketing teams can move faster and
