  1. Nikolaj Van Omme

    Nikolaj Van Omme

    Expert Mathematical Modeller and Optimization Specialist

    Canada

    Hi there, My name is Nikolaj and I'm a passionate problem solver. My background is both in mathematics (MD in pure maths, PhD in applied maths) and computer science (MD in computer science) and I have over 15 years of programming experience. My speciality in optimization is Arc Routing. I love to create complex algorithm and solve "impossible" problems. My computer science skills are not only theoretical (algorithm analysis, algorithm creation, heuristics tuning) but also practical. I have worked on several (big) industrial projects. Let me shortly present one success story. Challenge: Optimize the traffic lights for a city of the size of Brussels. The idea was to coordinate intelligent traffic lights to minimize the total travel time of the users. I had the pleasure to supervize a team of two and we managed to reduce the total waiting time by 30%. In my PhD thesis, I defined a new optimization problem (The Cumulative Chinese Postman Problem), studied its complexity, proposed 8 different models (out of 20!) and studied their relative strengths both theoretically and experimentally. The algorithms that I have developed were 2 to 133 faster than the state of the art solver at the time (2011). In short, I'm a perfectionist that enjoys solving complex problems.

  3. David Lundquist

    Software engineer

    Sweden

    Summary Ever since I can remember technology has been an important part of my life, this has taken me from founding my own small technology company back in Sweden to working on projects all over the world. This same focus on technology also allows me to have a broad understanding of how technology is evolving and it has given me the ability to widen my knowledge which is now spread across several different kinds of technological areas. References will be provided upon request. Specialities I am an experienced developer within the mobile sphere having built both back office software as well as fully fledged content delivery and billing solutions for some of the biggest carriers in the world. Ive had several titles in top lists in the apple appstore and on carriers across the world. While mobile has been my main focus the last couple of years my base lies in web where I have developed solutions to allow companies of all sizes to have a presence on the web. I’ve built systems and websites for everything from small local companies to big global companies. For the last couple of years my focus on web has been towards Ruby on rails using a BDD philosophy having finished both big and small sized projects by successfully leveraging cucumber acceptance tests and story writing as well as unit tests based around rspec. While being a partner in different businesses I have also gathered skills in business planning and management.

    Hello. My name is Vladislav and I'm programmer. I mainly engaged in software development in the languages C / C ++, support and maintenance of sites, development of web-scripts (PHP, HTML, MySQL) and design for the little things. Recently, a new discovery for me was the scope of development for microcontrollers. Also I have experience in networking Modbus and the 1-Wire for controlling different devices (different sensors, frequency converters, etc.) Some of my works you can see on my personal site: http://man197-soft.org

    Software development is a blend of art and science, an appeal to the creative and the analytical, an expression of inspiration and objectivity. For 20 years, I have applied my passion for software design to the practical demands of clients. The diverse range of projects to which I have contributed has strengthened not only my skill set, but my ability to approach new projects and software environments with confidence. My work with small companies has exposed me to all aspects of the software development process, including software design, database management, user-interface design, source code implementation, technical writing, quality assurance, and customer support.
