HARDWARE ENGINEER at JASWA VENDING PRIVATE LIMITED (2025-03 – 2026-05)

• End-to-End Product Lifecycle: Spearheaded the full-cycle development of an automated perfume vending machine, taking the project from a literal "napkin sketch" to a production-ready functional unit in 3 months.
• Mechanical Optimization: Engineered a custom 3D enclosure in Fusion 360 that reduced material costs by 75% and assembly complexity by 60% through integrated snap-fit components and optimized internal airflow.
• Communication Reliability: Architected a robust multi-protocol communication stack (UART, SPI, I2C) and integrated MQTT for IoT Connectivity, achieving 99.8% uptime in device-to-cloud data synchronization.
• Firmware Architecture: Developed modular, non-blocking firmware for the ESP32, allowing for simultaneous sensor polling, LED Matrix UI updates, and motor control without system latency.
• DFA/DFM Implementation: Collaborated with local vendors to ensure the mechanical design was optimized for laser cutting, reducing potential manufacturing defects by an estimated 30%

RESEARCH INTERN (GOVERNMENT-FUNDED R&D PROJECT) at IIT ROORKEE (2024-02 – 2024-04)

• Reverse Engineering & Signal Analysis: Performed forensic-level reverse engineering of PCBs and mixed-signal circuits using Digital Storage Oscilloscope (DSO), multimeters, and schematic reconstruction techniques to analyze signal paths and Analog Front-End (AFE) architectures.
• Real-Time Application Development: Architected a real-time telemetry and alert management application using Flutter, MongoDB, and Firebase, enabling live sensor visualization, automated alert triggering, and scalable user management for monitoring systems.
• PCB Design & Sensor Integration: Contributed to PCB design and embedded integration workflows for the ADXL355B MEMS accelerometer platform, focusing on reliable sensor interfacing, compact hardware layout, and system-level validation.
• Hardware & Embedded System Development: Engineered and validated embedded sensing platforms for earthquake early warning applications, integrating MEMS-based sensors, analog signal conditioning circuits, and real-time data acquisition workflows.
• R&D Documentation & Collaboration: Maintained structured technical documentation, iterative design reviews, and version-controlled development workflows using Git and Linux-based environments within a government-funded research ecosystem.
