About & Resume

➣ Hardware Architect

• Architected a versatile outdoor solar-powered platform for a family of IoT products. Designed for durability in harsh conditions, the platform featured a custom multi-zone solar cell, high-efficiency power harvesting circuitry, and graphene supercapacitors. This ensured reliable performance and a 5-year expected lifespan.

• Redesigned prototype products to improve performance, reduce costs, and enhance manufacturability. Collaborated with manufacturing to raise quality and reliability standards. Optimized power efficiency and functionality through targeted design changes. These improvements led to higher manufacturing yields and better overall product performance.

➣ Design & Sustaining Engineering

• Collaborated as a key member of a cross-discipline design team responsible for designing and sustaining industrial-grade products with a ten-year life expectancy from concept to medium-volume production. Leveraged the expertise of senior team members while offering a fresh perspective, resulting in the successful delivery of innovative and reliable hardware that exceeded customer expectations.

• Architected mixed-signal subsystems for multiple products that included analog and digital signals, embedded power supplies, microcontrollers, and various sensors. Designed low-noise analog amplifiers to condition sensor output waveforms and drive analog-to-digital converters, power supplies, and mixed-signal subsystems for new product lines. 

• Extended the useful life of the flagship product through comprehensive component analysis, circuit redesign, and PCB enhancements, prioritizing signal integrity, compliance, and cost-effectiveness. Proficiently utilized OrCAD/Cadence products, collaborated with third-party test labs, and employed advanced lab equipment for thorough validation.

• Successfully integrated LTE and Mesh radios, along with custom-designed antennas, into Sentient Energy Internet of Things (IoT) sensors. Collaborated with antenna designers and Mechanical Engineering teams to redesign PCBs for seamless integration, prioritizing product quality, cost reduction, and carrier requirements.

➣ Compliance & Test Engineering

• Architected and implemented over twenty design verification test programs and more than five engineering specification test programs to ensure product quality met organizational standards by defining passing criteria and using Python to automate measurements with typical lab equipment, such as oscilloscopes, logic analyzers, function generators, spectrum analyzers, etc. 

• Led the implementation and execution of 4G LTE Certification programs for Sentient Energy IoT sensors across major carriers, including AT&T and Verizon. Ensured product compliance with internal and carrier requirements, facilitating over seven PTCRB certifications and multiple GCF certifications in third-party labs.

• Collaborated with Manufacturing Engineering to optimize functional tester design, conducted in-depth failure analysis, and implemented corrective action plans. Reduced manufacturing cycle time through a comprehensive review of assembly processes, identification of irrelevant and redundant measurements, and recommendation of faster measurement techniques.

• Supported Quality Engineering with unit preparation for environmental stress testing, including HALT, HASS, 85°C/85 RH, Rapid Thermal, and other testing by reviewing the test plan and determining what metrics to record to indicate the quality of the device and provide data to Engineering to further refine the quality of the product. 

➣ Engineering Test Automation

• Created, documented, and supported a library of Python programs tailored to test and measurement equipment in the lab facilitating Engineers' automation of device verification testing (DVT). These programs simplified interaction with the equipment by providing a standard interface for multiple types of equipment, handled opening communication and interaction with the unit, and managed common errors the device presented automatically. 

• Developed canned automated tests in Python using the aforementioned library to facilitate common DVT efforts, such as measuring the transient response, ripple, line and load regulation of a power supply over temperature. These programs required little input as they handled finding the operating point and generated Excel and Word files with data and plots as outputs. 

➣ Engineering Lab Design & Development Network

• Designed the Product Development Engineering Lab by identifying the needs of the Engineering team and working in collaboration with the construction management company, construction design teams, and contractors to create a space for hardware development. 

• Restrictive policies from Corporate IT significantly hindered the use of the Corporate network for interfacing test instruments. Working with Corporate IT to meet all necessary security requirements, an isolated lab network was created. This network allowed the Engineers to change test equipment configuration as needed. 

➣ Schematic Standards Development

• Improved design time and reduced stress on supply chain management by creating a library of frequently used parts in Sentient products. Included were typical application circuits that had been tested and verified by Engineering supporting rapid prototyping in addition to reducing the design time and the number of iterations a design went through before reaching production. 

➣ Responsibilities

• Designed mission-critical power systems for a hospital and two data centers, ensuring uninterrupted day-to-day operations and preparedness for outage scenarios. Analyzed equipment power consumption and collaborated closely with clients to establish outage procedures, demonstrating a comprehensive approach to power system design.

  • Drafted power and data schematic diagrams and drawings for commercial building renovation and data centers in line with expected power and data requirements and applicable municipal codes. 

  • Estimated power requirements for commercial building renovation and data centers. 

  • Coordinated with Architecture, Civil, and Mechanical disciplines to optimize credits for LEED certification. 

• Designed commercial power systems for two private commercial building renovations, contributing to the successful modernization of these facilities.

➣ Initiatives

• CAD Standards Development

  • Improved sheet set organization and standard templates. Developed automated form templates to calculate credits for Title 24 LEED certification. Refined note and callout schemes. Created libraries of symbols for standard equipment across designs.
