About

Over the past year I shipped a computer-vision pipeline on edge hardware (21/21 QA detection accuracy, ~50% lower CPU), took a stalled vision-language model deployment to production on an RTX 5090 (deploy time 2 h to 15 min), and built the serverless data pipelines and data catalog behind a multi-tenant analytics product on AWS. My thesis was a full ML platform: LSTM demand forecasting and a PPO reinforcement-learning agent, orchestrated in Airflow with an RLHF retraining loop and served through a FastAPI microservice with hot model reload. I work across the whole path: data modelling and ETL, training and evaluation, serving, and the infrastructure underneath. CS degree with honours, two ICPC quarterfinals.

Computer Vision and model serving • Rebuilt the people-tracking / attendance pipeline on edge mini-PCs using OpenCV, YOLO, OpenVINO and ByteTrack, reaching 21/21 detection accuracy in QA and cutting CPU load by roughly 50% versus the previous version. • Took over a stalled vision-language model deployment on an RTX 5090 (32 GB) by diagnosing a CUDA / driver incompatibility with vLLM and moving to a reproducible uv-based install; cut model deployment time from about 2 hours to 15 minutes, and ran GLM-4.1V-Flash / Thinking and GLM-4.6 in production, including one-minute video inputs. • Built gue
