LEWUS ELECTRONICS
Welcome to Lewus Electronics.com. My name is Mark Lewus and I am a multi-disciplinary engineer and former director level technical manager. I am formally educated as a software engineer but I am equally adept at electronic hardware design, and also mechanical design for robotics and other small motion systems. I hold a Computer Science degree and 20 years of electronic, computer, and communications industry experience. I have been employed by a wide range of companies ranging in size from a "fifth person in the door" startup ($0 to $100M sales in 3 years) to Intel Corporation. I have professional capabilities in the following areas:
EMBEDDED & PC SOFTWARE DEVELOPMENT
- Embedded software development in C, C++, and assembly language on 16 & 32 bit platforms (ARM, ATMEL, MICROCHIP)
- Embedded Operating Systems: footprints very small to very large - 2KB "hand rolled" tasking through Embedded Linux
- PC software development in C++, primarily to support embedded projects
- Linux Administration (install, configure, networking, general administration)
- Networking: Ethernet, ZigBee, Bluetooth, Custom Mesh and Peer-to-Peer Stacks
- Robotics: autonomous navigation, inverse kinematics, dynamic stability, behavior-based control systems
WEB & GRAPHICS DESIGN
- Graphic Design, Media Creation & Editing: Illustrator, Photoshop, Premiere, After Effects (CS3/CS4); DxO
- Hand coded, W3C validation compliant, XHTML & CSS
- Tool-based website design with Dreamweaver (to CS4)
- Animation, Interactivity, and Scripting: Flash, Actionscript, Javascript (+Jquery), DOM Scripting, AJAX
- Server-side application development: PHP & MySQL on Linux and Windows Platforms (LAMP, WAMP)
- CGI: Python, some Perl
ELECTRICAL ENGINEERING
- Analog circuit design to transistor level
- Deep experience with operational amplifier circuit design
- Linear and Switch Mode power supply design to KW level
- Motor control including BLDC, multi-phase AC controllers to KW level
- Microcontroller system / hardware design on ARM, PIC24/32, AVR
- Service / Personal Care Robotics research (Electrical, Software, Mechanical/CNC Manufacturing)
- Technical writing & training: proposals, training presentations, competitive product evaluations, teardown and cost analysis, etc.
Due to failing health I am no longer seeking employment, but if you have an interesting open source project, your non-profit needs a website, or we have previously worked together and you would like to re-connect, by all means contact me at mlewus@lewuselectronics.com or find me on LinkedIn.
