RAHUL KUMAR

Xylem Optimyze – Condition Monitoring System.

• Developed embedded firmware for vibration, temperature, and pressure monitoring, using industrial sensors.
• Designed fault detection algorithms using magnetic flux sensors for predictive maintenance.
• Debugged and resolved a critical battery status detection issue, preventing production downtime, and ensuring uninterrupted field deployment.
• Optimized RAM utilization from approximately 90% to approximately 75% by refactoring firmware modules and improving memory management, enhancing system stability.

Residential Booster Pump – Aquacase.

• Designed and developed RTOS-based embedded firmware for automatic motor speed control, based on real-time water demand.
• Developed and integrated FOTA (Firmware Over-the-Air) and Bitbucket CI/CD pipelines, automating firmware builds and validation.

Low Water Cut-Off (LWCO) – Safety-Critical Controller

• Contributed to firmware development for a safety-critical Low Water Cut-Off (LWCO) controller, focusing on fail-safe behavior.
• Worked on implementing and validating firmware logic to interrupt electrical firing circuits when water levels fall below defined safe thresholds.
• Supported integration and validation of low-water alarm functionality, including fault-condition and abnormal-scenario testing.
