- EV Charger Development: Designed and developed Pakistan’s first AC EV chargers (7kW & 22kW) with peak tariff control, multi-level power adjustments, and app/web-based management using Bluetooth and Modbus protocols. - DC Fast Charger Projects: Oversaw the installation, testing, and maintenance of 60kW to 180kW DC fast chargers, ensuring compliance with IEC standards and reliability in urban and industrial environments. - Solar Inverter Integration: Programmed inverter firmware for hybrid and on-grid systems; integrated lithium-ion batteries using RS485 protocol and BMS communication. - Windows Monitoring Software: Developed a Windows application in C# to monitor real time inverter performance via RS485/RS232. Improved troubleshooting and data visualization efficiency by 40%. - Battery Swapping Station (EZbike): Integrated RS485 modules for real-time battery data transfer and implemented anti-theft mechanisms using intrusion detection systems. - High-Voltage EV Maintenance: Conducted diagnostics, repair, and calibration of high voltage systems in DFSK and other EVs, including battery management and onboard chargers. - Cross-functional R&D Collaboration: Worked with Chinese OEMs (Voltronic, Ritar, Afore) to debug, test, and improve inverter and battery systems. Played a key role in product customization and firmware localization. - On-grid Solar Installation: Led a team for the installation of a 60kW grid-tied solar power system, optimizing layout, system configuration, and commissioning. - Compliance & Safety: Implemented ESD-safe workflows and high-voltage safety protocols across testing labs and live installation sites. Tools & Technologies: RS485, RS232, Modbus, ESP32, STM32, MATLAB, Visual Studio, MPLAB X IDE, Proteus, AutoCAD, C/C++, C#, Python
