Case study · Enterprise healthcare
A patient portal for 2M+ monthly users, engineered from the ground up.
Over a three-year engagement, Dude Lemon was the engineering team behind the US patient portal for a major medical technology brand’s nationwide device recall program: built from the ground up, serving more than two million active users a month at launch, and continuously engineered to specifications set by program leadership at the brand’s North America headquarters.

01Overview
A patient portal that had to work the first time, every time.
The challenge
A nationwide medical device recall program needed a patient portal that could verify and serve millions of patients with no room for error. Every user needed to be matched to the right device and records, sensitive medical and personal data had to move under strict security standards, and the platform had to stay dependable as the program scaled.
Our approach
Dude Lemon owned the build end to end. We architected the platform from the ground up, designed the identity-matching registration, engineered secure data handling and transfer, and stood up encrypted audit logging, then iterated release after release against program specifications.
The outcome
The portal launched serving more than two million active users a month and ran as the program’s front door for three years of continuous engineering, with new device flows and capabilities shipped as requirements evolved.
02The collaboration
Worked with the brand’s engineering organization.
We worked directly with program leadership at the brand’s North America headquarters, building from their specifications, estimating and scoping each update, and shipping release after release across three years.
The cadence ran from first architecture through continuous evolution: new device flows, registration changes, and platform updates engineered as the program grew.
We also served as the liaison between the brand’s North America team and its Innovation Lab, ensuring the lab had the data access and testing information it needed for each of its releases.
03What we owned
From first commit to every release.
Ground-up platform engineering
We owned development end to end: architecture, build, deployment, and three years of continuous engineering, shipping each release to the specifications of the brand’s engineering organization.
Identity-matching registration
We designed the registration flow and the matching algorithms that verify each user through a multi-step process and connect them to the correct device records, so every patient reaches the right device and never another record.
Medical and personal data handling
The portal handles sensitive medical and personal data. We engineered storage and data transfer to the security standards required of a global healthcare enterprise.
Security operations and transparency
We delivered encrypted audit logs to the brand’s Innovation Lab engineering team on demand, and supported communications for each public release of the portal.

04Security & data
Built for the data that matters most.
Patient data carries the highest stakes in software. We engineered the portal so that identity is verified before access, data moves encrypted, medical and personal records stay separated, and every action can be audited, on a healthcare enterprise’s terms.
Verified identity
A multi-step registration process and matching algorithms confirm each user before any record is exposed.
Encrypted data transfer
Personal and medical data moves between systems under the security standards required of a global healthcare enterprise.
Separated data domains
Sensitive medical information and personal identifiers are handled with strict boundaries and least-privilege access.
Encrypted logs on demand
The brand’s Innovation Lab engineering team could draw encrypted audit logs whenever a release or review required them.
