About Me

Career Summary

Data Scientist and AI Engineer who takes a problem all the way from raw data to a system that runs in production. I build end-to-end ML pipelines, retrieval-augmented (RAG) chatbots over internal company documents, and computer vision systems wired to sensors and controllers on the factory floor. Comfortable across ETL and streaming pipelines (Kafka, Snowflake, Airflow), model training and deployment, and the dashboards that make the results usable by people who are not data people. 1st Place Winner of the Snowflake Hackathon Partner 2025. Currently taking on freelance projects in data science, AI engineering, and IOT.

AI on Your Internal Data

Chatbots that read your company documents (RAG), question answering over internal databases, and LLM workflow automation. Can run fully on-premise, so your data never leaves your own servers.

Computer Vision & IOT

Quality inspection on production lines, defect detection, and object counting, wired to sensors and controllers for automatic rejection plus real-time monitoring.

Data, ML & Dashboards

ETL pipelines, demand and sales forecasting, anomaly detection, churn and risk models, plus dashboards and automated reporting your team can actually read.
