IoT Systems at Imecar

Production IoT systems shipped over nine months. A smart meeting-room display ran on an ESP32 with FreeRTOS, one core for FastLED, one for the web server, with SOLIDWORKS enclosures laser-cut from aluminium and a Node.js, PostgreSQL and JWT backend serving real-time room state.

Local LLM Coding Assistant

Fine-tuned Qwen3-8B on five years of my own code into a local assistant that matches my style. A Python pipeline built a weighted dataset, then QLoRA via Unsloth trained it on an RTX 4070 Ti Super, quantized to GGUF and served through Ollama and Dockerized Open WebUI over Tailscale.

FruitGuard Risk Intelligence

A dual dashboard for the USDA Plant Protection and Quarantine hackathon that finds high-risk fruit fly entry pathways into the US. An operational map fuses ArcGIS layers and trade data; a predictive dashboard runs SageMaker XGBoost with twelve deployed model artifacts and a live inference endpoint.

Game of Life Simulator

A cellular automaton engine with three variants: standard, toroidal wrap-around, and a three-state lifecycle. The board is a flat std::string for cache-friendly traversal, with an interactive pause and rollback buffer and a full getopt CLI plus test suite.

Playlist Recommender

A cumulative recommendation engine in Java. It parses rating CSVs, then runs z-score normalisation, collaborative-filtering prediction, and K-means clustering, ranking in-cluster candidates by inverse distance for a top-twenty playlist across five CLI modes.

Hand Tracking Mouse Control

A real-time hand-tracking mouse controller with no inference-time model. It isolates motion with frame deltas in OpenCV, tracks offsets with NumPy, and maps hand position to the cursor through PyAutoGUI, with a planned TensorFlow gesture extension.

TuneSummary

Free listening stats for Spotify users, built from their own data export. The browser unzips the export and sends only compact play rows to a FastAPI and SQLite backend; the dashboard aggregates any date range client-side, and a canvas-drawn recap story exports as images or video. Email magic-link accounts and MusicBrainz genres.
