⚙️ Mini Gauge – Hyundai Coupé

Problem: Upgrading to an aftermarket 2DIN radio in Hyundai Coupé/Tiburon (GK FL 2002–2008) makes the original factory multi-gauge physically incompatible — it simply cannot fit.
Solution: A compact custom embedded device that displays battery voltage (hybrid ADC + CAN bus weighted average), coolant temperature from the Siemens SIMK43 ECU via CAN, and real-time fuel consumption (L/100 km while driving, L/h at idle).
Impact: Automatic night mode, 60 FPS UI via LVGL on a 1.28" round IPS LCD — seamlessly replacing the OEM gauge with no loss of information.

🚗 MyCarWallet

Problem: Car owners have no convenient offline-first tool to track fuel costs, maintenance schedules, and expenses across multiple vehicles without sending data to external servers.
Solution: Multi-vehicle garage manager with interactive analytics, fuel consumption tracking, OCR receipt scanning (Google ML Kit), automated maintenance alerts, and full offline SQLite storage. No data leaves the device.
Impact: Clean Architecture Android app that puts the user fully in control of their vehicle data, with a polished chart-driven dashboard.
