He is passionate about crafting user-centric digital tools and, over the years, he has developed many business web apps like collaborative work platforms, workflow applications, transactional e-banking and e-commerce websites. His expertise covers all stages of the application development life-cycle, from business/functional analysis, technical analysis, architecture and design, development and testing, up to production deployment and application maintenance.
