Engineered an EMV/NFC payment module for Apple Pay/Google Pay and secure key fob authentication, implementing AES/TLS-secured transaction handling to support PCI DSS compliance. Improved terminal uptime by 30% and reduced deployment cycles by 40–50% using rollback-safe secure OTA updates, achieving <1% field failure across mission-critical deployments.

Developed multi-threaded C++ middleware on ARM Cortex-M with FreeRTOS to acquire and validate real-time medical telemetry using DMA and interrupt-driven logic. Built IEC 61508 SIL-3 aligned BIST and watchdog fault escalation with TLS/SSL device-to-cloud telemetry, reducing deployment cycles by 40% and delivering <1% field error rate.

Integrated STM32 firmware for SIM initialization and power-triggered secure OTA workflows, building a custom bootloader with dual-partition flashing and rollback protection. Improved OTA reliability by 25% through delta patching, CRC/digital signature validation, and fault-tolerant update state tracking over low-bandwidth GSM/LTE networks.

Developed modular C++/embedded modules for real-time GPS and marine sensor acquisition using FreeRTOS/Embedded Linux with interrupt-driven low-latency pipelines. Built secure, low-latency TCP/UDP communication stacks with failover caching and cloud gateways (MQTT/REST) to improve resilient ship-to-shore logistics telemetry under lossy networks.

Designed high-performance C++ modules to parse, validate, encrypt, and generate XML-based configuration payloads for programmable radios. Implemented asynchronous multi-threaded event handling and AES-secured over-the-air configuration delivery with rollback safeguards, improving reliability of zero-downtime radio provisioning.

Integrated automated configuration generation into Jenkins CI pipelines with unit tests, coverage metrics, and regression hooks to streamline nightly build validation. Reduced programmable radio deployment time by 50% using secure XML automation and push-based provisioning with real-time callback/event monitoring.

Developed Java applications across web and desktop environments using object-oriented design and maintained enterprise integration services. Built and optimized SQL schemas and queries (MySQL/Oracle), implemented SOAP and REST services, and improved application quality with unit testing and JUnit.

Earned a Bachelor of Science from the University of Vadodara in 1992.
