About
Development Engineer with 1.5+ years' proven experience designing, developing, and shipping production-grade drone battery systems and power management firmware. Expert in Embedded C (STM32, AVR, Atmega, ESP32), PCB design (KiCad, EasyEDA), cell balancing algorithms, and thermal management.
Key achievement: Deployed 5 battery systems with 99.2% first-pass testing, 50% validation acceleration, 15% flight-time extension, and zero field failures.
Differentiator: Full-stack Embedded systems engineer—rare in early-career roles—combining firmware development, PCB design, battery chemistry understanding, and real-time thermal control and a Professional Battery Solder trained 15+ experts.
Experience
Development Engineer (Embedded & Battery Systems) at Dreamfly Innovation Pvt. Ltd. (2024-09 – Present)
5 Production Battery Systems | 100+ UAV Units Deployed | 99.2% Pass Rate | 0% Field Failures
- Battery Temperature Logger: Ultra-lightweight monitoring module (KiCad weight-optimized PCB, Embedded C ESP32 firmware, Python thermal automation). Developed specially for R&D testing; detected 4 thermal anomalies preventing in-flight failures; 90% faster validation.
- High-Current MOSFET Drone Power Switch: <5µs overcurrent response, <20mV drop at 100A+ discharge (KiCad, Embedded C interlocks, Python validation). Integrated across all Dreamfly UAV platforms.
- 4S–6S LiPo BMS for Drones: Complete battery management system with real-time cell balancing, SOC estimation, CAN/I2C flight controller integration (Embedded C state machine, KiCad full design, Python simulator).
- PASSIVE Cell Balancer (LIFE SAVER): Redistributes energy between cells during flight/charge; low-latency firmware (Embedded C). Extends flight time 15% at identical capacity; maintains ±4mV cell consistency across 300+ flight cycles.
- Smart Thermal Management (Cold-Weather): Closed-loop heating PCB for sub-zero battery preconditioning (−20°C). PID firmware + precision sensors. ±2°C stability; zero flight aborts in 10+ test missions.
- Specialized 12S-14S Master BMS: Engineered for maximum flexibility, this custom BMS is designed to meet the rigorous demands of specialized applications. Enabled to meet real Market demands.
- 50% weight reduction via aluminum-core PCB optimization for drone integration
- Python flight-test data pipeline for real-time in-flight battery health monitoring (60% documentation automation)
- CAN/I2C flight-controller integration with autonomous telemetry and safety heartbeat protocols
