Curriculum Vitae


Personal Profile
Experienced Systems Architect with extensive expertise in the following areas:
• Translating technical requirements into conceptual designs with formats to be usable by product designers, implementers and testers
• Making the translation from international and industry standards to products and product components under development
• Designing protocols and algorithms to control real time behavior of complex systems including multiple units interoperating over unreliable (wireless) links
• Designing protocol stack multi-thread architecture and inter-thread messaging
• Identifying patentable aspects of system design and preparing invention disclosure material and explaining the concepts to patent lawyers

Goals
My goals are:
• To analyse requirements and write architecture and design specifications, in a multi-disciplinary team consisting of system architects, technical experts, hardware and software implementers, protocol and conformance testers.
• To become expert in a number of technical areas.
• To use methods such as UML and associated tools as integral element of the produced specifications
• To be involved in the whole development cycle from requirements establishment to conformance testing

The following qualities help me to achieve my goals:
• Good analytical skills
• Good writing skills to make complete and unambiguous specifications
• Good knowledge of the English language
• Good interactions with other disciplines and openness to suggestions for changes and improvements
• Good listener; no fear to ask “dumb” questions to verify correct understanding
• Background in embedded software engineering
