Medicai was my main project during my tenure at Atta Systems.

As the lead product designer starting 2020, I was responsible for the end-to-end product design process from initial research through implementation, including designing and building the marketing website that now serves 60k+ monthly users.

Healthcare providers relied on $100k+ legacy systems that couldn’t support remote work, forcing many to use CDs for imaging even during COVID-19. Doctors needed instant, reliable access to 300MB+ files on any device, with zero room for error, all under HIPAA strict standards.

I embedded myself in Romanian hospitals for months, interviewing doctors, managers, and patients to grasp the full scope of the problems. The biggest insight: doctors weren’t necesarily against new tech, but they were rather scarred by failed rollouts.

Around 75% of diagnostic errors happened during handoffs, so our design had to be invisible, not flashy.

I mapped dozens of user flows across radiologists, physicians, patients, admins, and technicians, each with different needs. The workflows were archaic: image sharing still relied on burned CDs, uploads took multiple steps across multiple systems, and many used WeTransfer or email with low size limits, leading to pixelated or missing files. Lost studies sometimes forced repeat radiation exposure, an unacceptable risk.

I developed a rapid iteration approach that turned months of design into days. One day of shadowing revealed workflows and pain points, which I quickly translated into wireframes and prototypes tested with real users. This process surfaced key insights, like doctors preferring dark interfaces because dimly lit reading rooms improve their ability to detect subtle contrast in scans.

Over 50 interview and testing sessions were conducted with both doctors and patients.

One of the biggest challenges was building a zero-footprint DICOM viewer to replace $100k desktop software.

I studied how radiologists actually read scans: window/level changes every few seconds, scrolling through hundreds of slices, constant measurements, and historical comparisons. Beyond viewing, doctors needed secure collaboration across devices, with access to patient files, comments, and supporting documents.

Medicai met these needs while staying fully HIPAA and GDPR compliant, with ISO 27001 and ISO 9001 certifications for global standards.

Rather than building one interface that satisfies no one, we've created a three-tier interface strategy. Patients see one-click viewing with plain language and simple sharing via link. Referring physicians get essential tools with a focus on comparison.
