Welcome to My Professional Portfolio

Hardware Validation & Test Automation Specialist | Python | LabVIEW | Silicon & Board Validation

With over 13 years of experience across Hardware Validation, Test Automation, Semiconductor Validation, Automotive Testing, and Industrial Automation, I specialize in Silicon Characterization, Board Validation, ATE Testing, Python Automation, LabVIEW Development, Hardware Debugging, and Automated Test Solution Development. My career has evolved from Electrical Engineering and Industrial Automation to advanced hardware validation and test automation, enabling me to combine strong hardware fundamentals with software-driven validation expertise.

Most recently, I served as an Associate Manager at HCL Technologies, where I worked on silicon characterization, hardware platform validation, board-level testing, and automation development. My hands-on experience includes DDR characterization across PVT conditions, validation of UART, I²C, DMIC and SB-TSI interfaces, power and thermal validation, CPU stress testing, Wi-Fi performance testing, laboratory instrument automation, and hardware debugging. I develop reusable Python and LabVIEW-based automation solutions that improve validation efficiency, reduce repetitive manual effort, and enable reliable data acquisition, analysis, comparison, and reporting.

My Expertise

  • Hardware & Board Validation – Developing and executing hardware validation test cases, performing board-level testing, hardware debugging, board bring-up support, and validation result analysis.
  • Silicon Characterization – Performing DDR characterization across multiple PVT conditions and validating interfaces including UART, I²C, DMIC, and SB-TSI using automated measurement environments.
  • Python Test Automation – Developing reusable Python utilities and automation modules using modular programming, object-oriented concepts, exception handling, data processing, logging, result comparison, and automated report generation.
  • LabVIEW & ATE Development – Developing LabVIEW-based automated testing applications, reusable test modules, automated test sequences, data acquisition solutions, and ATE-based validation systems.
  • Test Instrument Automation – Automating laboratory instruments including Oscilloscopes, SMUs, DMMs, AWGs, Electronic Loads, Current Probes, and NI DAQ systems for measurement and validation.
  • Communication Protocols & Interfaces – Hands-on experience with UART, CAN, SPI, I²C, JTAG, Modbus, RS-232, NI-XNET, NI VISA, FTDI, and related hardware communication environments.
  • Automotive, EV & ADAS Validation – Developing automated endurance-testing applications, CAN bus data logging, and automated test sequencing for UDS diagnostic validation across EV and ADAS platforms.
  • Industrial Automation – Developing PLC-based special-purpose machines, conveyor systems, endurance-testing solutions, electrical control schematics, HMI applications, and hardware integration and commissioning solutions.

Professional Journey

My engineering journey began in 2012 as an Electrical Engineer, building a strong foundation in electrical systems and engineering operations. I subsequently moved into Industrial Automation at DatCAM Automation, where I worked with PLCs, LabVIEW, HMI, Modbus, servo motors, VFDs, sensors, pneumatic systems, electrical design, hardware integration, testing, and commissioning. This experience established the hardware and automation foundation that continues to support my work in advanced test engineering today.

My career then progressed through ATE and automotive validation roles at Sanmina SCI and L&T Technology Services, followed by Test Lead assignments at Tessolve Semiconductor and SpicaWorks. These roles expanded my expertise into automated hardware testing, wireless battery charger validation, CAN-based automotive validation, EV and ADAS testing, semiconductor environments, and Python-based test automation.

At HCL Technologies, I advanced from Lead Engineer to Associate Manager while continuing to build strong hands-on expertise in hardware validation and automation. I worked on silicon characterization, board validation, hardware debugging, laboratory instrument automation, system-level validation, and reusable Python and LabVIEW automation solutions. My work included DDR characterization, interface validation, power and thermal testing, Wi-Fi performance validation, CPU stress testing, and automated data processing and reporting.

Vision & Dedication

My professional goal is to continue growing as a specialist in Hardware Validation, Test Automation, and Engineering Development, contributing to technically challenging products and next-generation validation environments. I am particularly interested in opportunities where hardware engineering, semiconductor validation, Python automation, LabVIEW, test instrumentation, and intelligent test development come together to solve complex engineering problems.

I believe effective validation is not simply about executing test cases; it is about understanding hardware behaviour, identifying failure patterns, automating repetitive activities, improving measurement reliability, and transforming test data into meaningful engineering insights. With a willingness to continuously learn, strong dedication, and a problem-solving mindset, I aim to develop scalable and reusable validation solutions that improve test coverage, engineering efficiency, product quality, and overall development outcomes.
