Hrishi has particularly strong expertise in embedded C, C2000 architecture and peripherals, digital control, firmware architecture, and system-level debugging. One of his greatest strengths is troubleshooting complex issues that cross the hardware/firmware boundary. Working together, we were able to correlate firmware behavior with hardware measurements, identify root causes, and develop practical solutions to difficult system-level problems.

Allen AnalianSr. Electrical & Electronics Engineer, Mission Critical Electronics

Hrishi led the microcontroller programming and digital control implementation for all bidirectional (15kW and 120kW) and unidirectional (15kW) converter designs. His intelligence and depth of knowledge are extraordinary, and he has a rare ability to understand complex technical challenges quickly and translate them into practical, reliable solutions.

Ahmed YagoElectrical Design Engineer, Crane Aerospace & Electronics

Hrishi's proficiency in TI's toolsets and valuable experience with phase-shifted full bridge/PFC/inverter control design was a major asset to our company and allowed us to develop a bidirectional design from scratch.

Julia TuckerTechnical Lead, BioLite

Even though the project ran over the December holidays, we had on-time project execution and timely and clear communication to keep the project moving along. I appreciate Hrishi going above and beyond the scope by implementing some aspects using CLA code as it improved the performance and reliability of the implementation, even though it wasn't in the original agreement.

Johan StrydomVP Applications Engineering, EPC

If you are looking for a seasoned embedded software consultant to support and accelerate your TI C2000 application development, then Hrishi is definitely the person you are looking for. All project deliverables were received on time and it was in general a pleasure to be working with Hrishi.

Dominik NeumayrLead Power Electronics & Electrical Engineer, Daphne Technology

While we were working on an electric vehicle battery charger back in 2010 he came up with a novel digital power algorithm to significantly improve power factor correction in discontinuous conduction mode. Hrishi is the kind of person you can trust to get the job done and get it done correctly. I have great respect for his character and intellect.

John RiceSr. Member Technical Staff, TI

I have worked with Hrishi for just over a year and half. I must say it has been an awesome experience... Hrishi did the schematic layout for our product that went into production. He also replaced a few key components that helped improve the overall functionality of our board while also bringing the overall cost down. Hrishi was so thorough on his initial schematic that his initial board layout is what we went to production with.

Mark StrawnVP of Hardware, NeoSensory

He possesses a unique set of skills which have been used to solve very challenging technical issues. Hrishikesh’s professional work has been recognized both within TI and externally, and he is referred to as the expert on digital power and control.

Ken SchachterC2000 Technical Staff & Training Manager, TI

He architected the complete digital control implementation of an ultra-advanced topology MHz CrM PFC using wide-band-gap GaN devices (TIDA-0961), which addresses the key challenges such as high efficiency and high power density, which are critical in automotive and industrial applications. He has expert practical experience in soft switching converters such as LLC, PSFB and with motor control system design.

Manish BhardwajSr. Staff Systems Engineer, TI

Hrishi is by far one of the best applications engineers I have ever worked with. I am super impressed with his work ethic and dedication to solving problems. He always shows patience and professionalism when working with customers and has a great ability to communicate steps taken and next actions as he assists through debugging.

Jackie FilbyTechnical Sales Rep & Distribution Business Manager, TI

He has the unique combination of skill sets involving digital as well as analog systems in power electronics and power conversion systems. He continually delivered results, went above and beyond in providing exceptional support, and showed genuine integrity and respect as an application engineer.

Mohammed ArefeenApplications Engineer, TI

His technical expertise in the field of digitally controlled power electronics is of the highest caliber. In our respective roles, I had to refer to him on numerous technical issues. He never disappointed me and in turn TI’s customers.
