About Elie Ratsyborynskyy

Summary • Extensive experience in Software Development in Web based solutions. Designing and implementing highly scalable solutions.• For several years, I have been working on .NET and PHP projects. My first exposure to Ruby on Rails took place around 2009 and since then I have been working with this technology as well as looking for opportunities to develop in ROR further. • My strengths are in generating ideas and solutions to complicated issues, developing and producing quality product, as well as leading the team successfully towards the project goal.• For a few years, I have been a peak resource with specific assignments for contingency projects, where I had to lead the team of developers and manage the effort of rescuing the projects. • Being a well-rounded individual, I develop my skills and knowledge through different initiatives, such as workshops, seminars, trainings, some of which I have conducted in past, e.g. “Getting real” by 37signals.• Working and contributing open source to Rails community, creating gems. • Superb communication skills and experience in building teams as well as creating professional and reliable atmosphere among team members.
