    Business Analyst / UX Expert / Requirements Consultant

    Colombia - Last active: 1 month ago - Tests: 4 - Portfolio: 6

    WHO I AM I'm a seasoned business analyst / UX expert with more than 10 years of experience in the IT field. WHAT I DO - User stories - Use case modeling - UX using dynamic Axure prototypes or static wireframes whenever necessary. - Information Architecture - Business process modeling I also consult on how to set up requirements process and fine-tune it to fit the project and development methodology that is being used. MY APPROACH Common sense. Occam's razor. And the notion that you do not design a solution until you've analyzed the problem. WHERE I AM I'm a digital nomad, I'm travelling around the world as I work. At this moment I'm living in Cartagena, Colombia. I'm here until July, after that I'm back to Europe. AM I AVAILABLE Yes, I do have some free time at the moment, ~20 hrs/week. So if you have a project that needs a meticulous and responsible business analyst, please feel free to contact me, I`ll be happy to help. *** RISK-FREE TRIAL *** Depending on the project, I may be able to offer you a risk-free trial to let you see how I actually work. The way it works is as follows: we agree on a task that's worth a few hours, I deliver results (no strings attached), you decide whether I'm a good fit for you. If yes, you hire me, and I bill you for those hours. If not, we just move on, no harm done.
