Rob Chambers

Rob Chambers

Python expert and scientific software architect

United States - Tests: 2

I'm a highly trained, expert engineer with excellent academic and industrial credentials. American, native English speaker. My degrees are in Mechanical Engineering, but I've found that my true love is software development. I love working on teams with other passionate and technically savvy people, but I have plenty of experience in management and report-writing. I am currently in the midst of long-term world travel, so I'm looking for quarter- to half-time freelancing work. I can work sporadically and long-term, but I can also settle down temporarily and put in very heavy hours when needed. I'm an expert Python programmer (5+ years experience) and I have several years combined experience in other languages as well (HTML/JS/CSS, MATLAB, C/C++). I am a full stack developer, with experience administering on-site and cloud servers, writing server-side and client-side software, developing complex and parallelized data processing algorithms, and implementing web- and desktop-based UIs. I have worked on many small projects where I am the sole developer, but I have also led 5-10 person teams to develop larger systems. As a mechanical engineer turned software developer, I have a special interest in working at the intersection of software with math, science, and engineering. Fields of interest: Biology, numerical simulation, algorithms, software development. Particular competencies: Taking ownership of solutions from conception to delivery... problem specification, algorithm development, software implementation, testing, and distribution. Skills/tools Python (including Numpy, Scipy, Pandas, Scikit-Learn, Cython, SQLAlchemy, Enthought Traits, Anaconda, IPython Notebooks, etc.). Web and Hybrid Mobile App development (HTML/JS/CSS; AngularJS; Cordova, Ionic), MATLAB (including many toolboxes). Experience building and administering Amazon Web Services (AWS) systems. Comfortable with Windows, OS X, and Linux.

Steven De Blieck

Lean data strategist

Belgium - Tests: 1 - Portfolio: 2

30 seconds summary: ---------------------- (If you have a minute, check out for a more visual overview.) Setting up a (digital) strategy takes a lot of time and money. In these changing times, waiting 2 months for results is already too late. Local (often identical) consultants result in high costs. Their results are often not grounded in evidence, and implementation is left entirely to you. With me, you know my value from week 1 instead of week 10. I use complementary ideas and scientific evidence to come to a result, while overhead costs are kept to a minimum. I work mostly remotely, via weekly renewable sprints. I pose a concrete question, divergently look for solutions and test them. This ranges from strategy, to planning, to implementation. Every project, I'm also coached by at least one very successful entrepreneur. What we can do together? --------------------------------- - HR: Assess job applicants by using proven predictors of success via data science and an evidence-based approach. Mitigate the interviewer bias. - Marketing: Persuade customers' irrational side by using data science and behavioural economics, instead of expecting them to be rational. - Innovation: Find key innovators in your company efficiently by bridging data science and sociological research, instead of drawing network graphs manually. - Finance: Make investment decisions based on data, instead of heuristics. - Pharma: Improve medication adherence by triggering patients via tech, instead of telling them what they already know. - ... Why I do this? ------------------- I am a generalist that wants to understand everything. One of my hobbies is sucking up as much information as I can about a topic. Few feelings are more wonderful than connecting things from different fields, that seemed independent at first. And if these new ideas can be meaningful to individuals/companies, it fills me with joy. That, in short, is why I love providing my consulting services. My background ------------------- I have a formal education in both Computer Science and Physical Therapy at Ghent University. Additionally, I completed online university courses on topics like law, finance, physics, etc. I have done technical work in large companies (e.g. Barco and PicanolGroup). I founded 2 companies, one in cause-related marketing (where I lead to 2 team members), and one in digital strategy consulting. I was awarded the statute student-entrepreneur for my increasing entrepreneurial successes during my student years, when I additionally also produced a film. I feel very privileged to have had these diverse experiences. In my adventures I have come across fascinating people with captivating ideas. It is via combining all these things, with technology as a catalyst, that I tackle business problems.
