Toyota Material Handling, Inc - Main
- Created hundreds of system requirements based on product design requirements, improving development efficiency by reducing misunderstandings and rework, covering unhappy paths and edge cases, modularizing the system, and driving testing.
- Designed a CANopen object dictionary to enable communication between a Linux Data Handling Unit and an RTOS/TouchGFX Display Unit. The design was flexible and efficient, focused on swift response times and clear separation of concerns between the DHU and DU.
- Implemented Python and JScript scripts to import, export, and match requirements among Azure DevOps, Microsoft Excel workbooks, and the Enterprise Architect CASE tool. Accelerated script creation and maintenance through the use of AI tools.
- Created UML state machines for complex modules and sequence diagrams for complex communication use cases, which helped developers to implement the modules properly.
- Oversaw consistency of the product features, including consistency of the user interface, to improve customer experience.
- Contributed to the establishment of a core design process for firmware development, including designing a requirements system that enabled product estimation, test tracking, and project scheduling.
- Designed major features, including communication between processors. The design was documented with state diagrams, message specifications, and requirements, all cross-referenced to assure complete coverage. This allowed efficient parallel development.
- Worked closely with the business team to help them take their rough ideas and form them into a detailed product definition.
- Provided inputs and consultancy to the management of external developers and project management.

Experience
Invention of new Algorithm for Solving NP-complete Problems
Design and development of new algorithm for solving NP-complete problems. The new algorithm has been published in the Artificial Intelligence Journal of Elsevier Science and presented on 5th International Symposium on
Artificial Intelligence and Mathematics.
Artificial Intelligence and Mathematics.
Optimization of Screen Resolution Transformation for ATARI Computer
Design and development of driver that allowed displaying of virtual black&white screen with higher resolution on lower resolution color monitor by real-time transformation of the B&W image to grade of shade. Significant challenge was limited computing power of Motorola 68k processor (no BITBLT included), so the driver had to be extremely efficient and sophisticated, to not affect performance of actual programs running on the computer.
C++ Multiplatform Library for Client Communication With Server
The project was developing a static library in C++ and using GTest. The library was intended for client applications on many platforms to allow communication with the server using API and JSON. I was in the role of developer. The design was used was focused on clean, lightweight objects with callbacks.
