Real-time deforestation detection fusing LoRa IoT sensors (10 km range) with temporal GIS analysis to flag illegal logging. Built the full ingestion → processing → GIS mapping → alerting pipeline with on-edge ML event detection under low-connectivity, plus MRV-aligned carbon verification (Verra/Gold Standard).
Edge-to-central AI workplace-safety platform: YOLOv8n + ByteTrack perception nodes with dual-stream splitting and debounced event state machines stream over Redis to a FastAPI hub (Postgres + live SSE dashboard). ONVIF/RTSP discovery, MQTT/webhook adapters, MinIO clip storage, and Prometheus/Grafana — 8 services via Docker Compose.
Modular FastAPI backend for an AI career platform — resume generation, adaptive learning modules, and a tutor with long-term memory and behavioral feedback. Context-aware services use Pinecone vector retrieval for semantic search and memory recall, driving scenario-based skill assessments.
Accessible mobile app helping visually impaired parents safely administer medication — on-device YOLO (TFLite) bottle detection plus ML Kit label OCR, with an offline-first SQLite architecture synced via Go cloud functions.
Network-wide parental-control DNS proxy with an SQLite policy engine, time-based filtering, and audit logging. The DNS hot-path is hand-written in RISC-V Vector (RVV 1.0) assembly, driving a 35% throughput gain to 63,500 queries/sec.
Multiplayer Rock-Paper-Scissors on Solana for a commercial client — Anchor + ephemeral rollups for ~10ms block times, a dual-currency SOL escrow with 95% winner payout, and secure WebSocket matchmaking.
Distributed search engine built as 5 independently-scalable Rust (Actix) services — crawler, indexer, searcher, ranker, storage — over Elasticsearch, with a retry-safe crawl→index pipeline and Prometheus/Grafana dashboards.
