20 years App modernization & engineering
For two decades we have brought apps forward: a modern redesign, a rebuild on native or cross-platform technology, and AI features your users will actually use. Testing, security and HIPAA, SOC 2 Type II, GDPR and PCI-DSS readiness come built in, and new apps get the same team.
Today’s medication
Representative app types, designed for illustration.
App modernization
Much of our work begins with an app that has fallen behind: a dated design, a framework nobody wants to maintain, releases that take too long. We redesign it, rebuild it on modern technology and add AI where it helps, while your users keep working.
We review the code, design, data and risks, then give you a clear path and an estimate.
Current platform conventions, adaptive layouts for every screen and accessibility built in.
Native or modern cross-platform, released module by module while your users keep working.
Assistants, smart search and automation wherever they make the app more useful.
AI integration
We add AI where it makes the app genuinely more useful: answering questions from your own content, summarizing records, reading documents and photos, and personalizing what each person sees. Private by design and measured before it ships.

Answers drawn from your own documents and data, with sources shown and permissions respected.
Find anything in plain language, and turn long records into a few clear lines.
Scan, recognize and transcribe, on the device itself when privacy calls for it.
Accuracy measured before every release; quality, speed and cost watched after launch.

Services
Security and quality services apply to any app, including ones built by other teams. Ask for a penetration test or a device-lab QA pass without a build engagement.
Technology
Chosen per product: native where the platform matters most, shared code where it serves the roadmap. Adaptive layouts for phone, tablet and foldable are a requirement, not a stretch goal.
Swift and SwiftUI, multi-pane layouts, on-device machine learning.
Kotlin and Jetpack Compose, foldable-aware layouts, managed device fleets.
React Native and Flutter, with native modules where performance demands them.
Offline-first sync, Bluetooth LE, camera, payments, EHR and HR integrations.

Compliance · Security · Accountability
HIPAA, SOC 2 Type II, GDPR and PCI-DSS requirements mapped to app and infrastructure controls, with evidence collected as we build.
Penetration testing of app, API and cloud plus OWASP MASVS assessments, by engineers who did not write the code.
Dedicated teams join your repositories, pipelines and rituals, with least-privilege access and contracts that match the risk.
