I build, deliver and lead agile teams with a focus on (but not limited to) the US healthcare sector. I also assist customers in a personal capacity by filling software architecture or interim technology executive positions.I achieve this through my company, Mediabrief, that delivers consulting and outsourcing services, specialized on modern cloud solutions and technologies: Java (Sprint Boot), PHP, React, AWS, Google Cloud Platform, Microservices. In over 20 years of activity Mediabrief has helped several clients in all stages of their lifecycle - from writing the first line of code to acquisitions by names such as Accolade (ACCD) or Zillow (ZG). I have helped clients setup their technology organizations and processes from scratch or just augment their existing teams and implement process improvements. I have occupied various executive or architecture positions including being the Principal Platform Architect at 2nd.md for 5+ years leading to their 460MM acquisition by Accolade.
