›SignWave — Real-Time Sign Language Recognitionexpand2024
Wearable sensor glove that translates ASL hand gestures into speech in real time — 98% classification accuracy with sub-second end-to-end latency.
Approach
Flex and IMU sensors embedded in a glove capture finger bend angles and wrist orientation on an ESP32, streaming raw motion data over WebSockets to a cloud-hosted Random Forest classifier trained on labelled gesture sequences. Classified output is passed to a text-to-speech engine and played back in real time, closing the loop from gesture to spoken word without any manual trigger.
Impact
98% classification accuracy across the ASL gesture set with sub-second latency from gesture to speech; end-to-end pipeline runs on commodity hardware with no GPU.

›Last-Mile Delivery Optimizationexpand2025
SQL-driven diagnostic study on a large last-mile delivery dataset isolating peak-hour delay patterns, with a clustering-based batching simulation to estimate dispatch efficiency gains.
Approach
PostgreSQL CTEs, window functions, and grouped diagnostics decompose delays by hour, traffic density, weather, and city; dataset split into a star schema (rider, city, vehicle, route dimensions + delivery fact table). K-Means clustering over geospatial order points with time-window constraints simulates batch dispatch. Power BI report for executive storytelling.
Impact
Peak-hour bottleneck patterns fully evidenced across operational dimensions; batching simulation produced directional efficiency gain estimates under available data constraints.
