    iOS Developer and Software Engineer

    Colombia - Tests: 6 - Portfolio: 1

    I'm an iOS Developer and Software Engineer. I have a degree in Electronics Engineering, so I learned programming with C and C++, from low-level microprocessor APIs to modern C++ SDKs like Qt. After I graduated, I became interested in developing mobile apps, iOS development in particular. Since then I've been coding Objective-C based apps and have acquired experience with Apple's Cocoa Touch (UIKit and Foundation frameworks); recently I started coding in Swift and I look forward to continue doing so. My skill set includes: * 3-year experience in iOS development * C/C++ and Object-Oriented Programming background * Leadership, responsibility and appropriation of assignments and tasks * Constant interest for learning * Entrepreneur and business-focused attitude * Research capabilities and ability to solve problems * High level of English language

  2. 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.

  4. 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.

  5. Anthony Cherro

    Programmer/Analyst with over 20 years of experience.

    United States

    My overarching goal as a programmer is to create products that provide true value to my customers. I try to follow the core agile development principles as much as possible because I believe the principles are sound and proven when properly applied. My experience in software development and deployment over the last 20 years has shown me that a truly useful application will prove itself quickly and provide value for years if managed and maintained properly. A large part of that management/maintenance is listening to customer feedback and improving software, techniques, and documentation whenever possible. As an analyst, I spend a great deal of time monitoring, discussing, and studying processes so that I am able to better suggest alternatives or better directed efforts at streamlining processes before starting the development cycle. This is often crucial to producing a valuable, effective solution.
