A selection of real projects — web apps, IoT systems, and Python tools built for clients and personal learning.
Autonomous Off-Grid PV System — Bachelor Thesis
Complete design and hand-built construction of a small off-grid solar power system: a custom pure sine wave inverter (EG8010 SPWM controller, IR2110S gate driver, IRFB4110 full bridge) on a self-designed PCB, a 4S Panasonic 18650 Li-ion battery pack, and buck/boost DC/DC charging from a 12V panel. Verified with oscilloscope waveform analysis and field-tested delivering stable 230V/50Hz AC.
