I am a passionate web and e-commerce developer with solid experience as a freelancer, a web development lecturer in private education, and a specialist in CMS and e-commerce (Magento) solutions. I’m quick to grasp new ideas and concepts, and I’m able to develop innovative and creative solutions to overcome technical and business challenges. My self-motivation and determination enable me to meet even the tightest deadlines, performing effectively under immense pressure – and I’m committed to each and every project, having once worked over 26 hours straight for a client to develop a long-term fix. Clients consider me a strong communicator, problem solver and analytical thinker who takes an interest in all areas of their business – not just the tech side.
