C++ programming expert |
Though he has worked with a great many programming languages, Expert has established substantial expertise in C and C++. In support of these languages, he has worked with compilers and development suites from Microsoft, GNU, IAR, Keil, Borland, IBM, Watcom, and several others. Expert has worked on several projects where each language was used alone, and on some where they were used in a mixed language environment. Expert is aware of semantic differences that exist between C as a stand-alone language and C as a subset of C++, and the software defects that can arise from not having this understanding. In both languages, he is adept at designing very efficient algorithms and at performing performance optimizations on existing algorithms. For C++, he is familiar with polymorphism, inheritance and class hierarchy design, pattern application, template metaprogramming, and safe use of templates. In addition to original software development, Expert has performed extensive automated and manual analysis of such systems for safety attributes, quality assurance, and maintenance purposes. He has developed C and C++ coding standards for use by software development organizations of 5 - 50 programmers; including some that were involved in safety-critical development. |

Throughout his career, Expert has held a research interest in programming languages, and has worked with a number of them. He has worked extensively with imperative languages such as BASIC, C, Pascal; and object-oriented languages and hybrids such as Smalltalk, Java, Ada, and C++. He has worked with low-level languages including Forth, and Postscript; Python, Rexx, and number of other scripting languages; and assembly languages for a number of processors and micro-controllers including 8-bit, 16-bit, and 32-bit architectures utilizing CISC and RISC. Some of the more unusual languages he has worked with include Labview, LISP, Forth, HPL, and A+ (a proprietary derivative of APL). For two of his clients, he worked to improve proprietary scripting languages for test and simulation, and enhanced interpreters for these languages. Academically, Expert gained experience with Prolog, LISP, ML, Fortran, Cobol, Modula-2, Modula-3, and Icon. More than just having worked with all of these languages though; Expert had an interest in understanding their similarities, differences, and relative benefits. He has researched several of these languages in depth, looking at issues of efficiency, semantics, and domain suitability. He has gained a solid understanding of the relative strengths and weaknesses that a programming language brings to bear on a project. |

On assignment at Honeywell Aerospace, Expert developed applications and libraries for the Air Data / Inertial Reference Unit (ADIRU) flight computer destined for the Airbus A380 "superjumbo" airliner. His primary work was performed in conformance with DO-178B/ED-12B Level A standards. He was also charged with a substantial update of the organization's software development standards. Expert successfully facilitated the resolution of technical issues among two Honeywell software organizations and their customer, Airbus. When a serious issue was discovered with a legacy ADIRU product, Expert was brought in for his general systems knowledge and analytical abilities, as the only member of the investigative team who had not been involved in the original product development. In all, Expert has participated in the design, development and test of 3 different Honeywell aerospace systems; all of which were developed at level A or level B of DO-178B standards.
|
In a prolonged engagement with Medtronic, Expert helped to establish a new automated test system for verification of PCD (pacer-cardio-defibrillator, a specialized "pacemaker") firmware and hardware. His involvement here included circuit board modifications, software library development, station build-up, development of calibration procedures, and test developer/user training. He also participated as a member in the firmware verification team. Because his expertise with the automated test systems, he was later assigned to the R&D group to aid in the test station development and firmware verification for a new family of Atrial PCDs. This group then spun off as a product group, and Expert joined the software development team for the real-time programmer device, used by physicians to communicate with Medtronic PCDs. Expert's efforts and expertise greatly contributed to bringing to market 4 different PCD products.
|
During an assignment with Honeywell's sensors division, Expert developed firmware for radio-frequency (RF) remote control receiver and transmitter devices for the rail transport industry. He was selected for this assignment especially for his expertise in the C programming language and his background in RF communications and telemetry. He established development standards and mentored other software developers, who had previously only developed software using assembly language. Following the completion of the software, Expert was re-assigned to the hardware team, where he advised on several circuit modifications, and aided in integration testing. A few months after the assignment ended, Expert was called in to advise on a "problem" the group was having in their tests. The Honeywell team was unable to detect any message corruption even when inducing large amounts of RF noise into the system for prolonged periods. This was an unexpected result, since the communication protocol was very simple and had only basic integrity checks. Expert was able to quickly allay concerns of hardware / testing anomalies, by explaining that he had anticipated that the devices would be expected to operate in very noisy industrial settings and had developed a noise immunity algorithm in the receiver's driver software. Upon pointing the team to the documentation of the algorithm; the team was elated by the results they had seen, and Expert was congratulated on a job well done.
|
Over several assignments with DataCard, Expert served in various roles as team member, applications architect, technical lead, and Project Manager. As a driver architect, Expert was contracted to create driver software for a specialized printing device. He developed a new architectural framework for serial memory card (smartcard) personalization drivers, and implemented a number of drivers using the framework. He met schedule and cost constraints with a solution that far exceeded performance and memory consumption expectations; while yielding the further benefit that new cards can be added in about than 10% of the time previously required. As a project manager, he always exceeded client expectations with regard to budget and schedule; in one instance saving 70% of estimated effort for an application upgrade by taking advantage of technical features in their existing system that hadn't been previously considered; as an added benefit, this solution exposed DataCard to much less risk than the originally planned approach.
|
With over 25 years of software development experience, Expert has created software and firmware for many different purposes. He is adept with the use of structured and object-oriented techniques of software construction. He is familiar with several methodologies and techniques, including RUP, Shlaer-Mellor, Booch, MDA. His programming language background includes C, C++, Java, Ada, Pascal, LISP, Prolog, Smalltalk, BASIC, and Forth; as well as several scripting languages, and assembly languages for a number of microprocessors and controllers. He has worked with many desktop and real-time operating systems. While he is also skilled in matters of hardware and test, he has established himself as an expert in all phases of the development of high-assurance software systems for safety-critical applications.
