Zbigniew Pieslak

Expert Ruby on Rails & Javascript Web Developer

Poland - Tests: 8 - Portfolio: 8

Over the last 7 years I have acted as a web developer and a Ruby on Rails expert, having the privilege of working with large international enterprises (NBCUniversal) as well as many promising startup companies. I consider myself to be a hard-worker motivated to deliver only a well-tested, scalable and performance-wise code that meets the current programming standards. During my career, I learned that understanding client's needs, good planning, proper programming experience as well as regular and honest communication are the key factors to build a successful relationship. Please have a look at my portfolio and the feedback I got from my clients. I’m passionate about learning new tools and programming languages and I quickly adapt to new environments. I’m seeking long-term relationships and new challenges. I am looking forward to hearing from you about your next project!
