Omi Health Tech Builds Vietnam's National Digital Health Infrastructure
CEO Phan Manh Hung discusses transitioning to product-based development using Java-centric tools.
1National Health Data Infrastructure
Omi Health Tech is building foundational digital platforms for Vietnam, specifically the Omi Health Platform and Omi LGSP. These systems standardize clinical data from hospitals and laboratories, propagating it to the Ministry of Health. This infrastructure enables health data to integrate seamlessly with Vietnam's broader National Data Exchange Platform for public services.
2Transitioning Business Models
The company evolved from a service-based model, which focused on building software for Japanese clients since 2012, to a product-based approach. This shift required a fundamental change in mindset and architecture. CEO Phan Manh Hung notes that product development demands more aggressive refactoring and genuine ownership of the codebase compared to client-spec work.
3Regulatory Compliance Challenges
Vietnam introduced new data protection and AI laws within a few months of each other, creating significant pressure. The team had to update data-access layers, audit trails, and consent flows across multiple repositories on a very tight timeline. These regulatory requirements necessitated rapid, safe, and precise modifications to their core clinical data systems.
4Java Core Development
The core of Omi's platform relies on a Java and Spring Boot layer that maps and transforms clinical data. Because this codebase is schema-heavy and highly regulated, the team adopted IntelliJ IDEA Ultimate. This tool allows engineers to perform complex multi-file refactors that would otherwise be risky or require manual, error-prone sequence operations.
5Efficiency in Regulatory Updates
In early 2026, a regulatory update required explicit consent capture for every read of identifiable patient data. Using IntelliJ IDEA's Change Signature and Find Usages features, the Java team implemented these changes in days rather than weeks. This efficiency was achieved with no production rollbacks, demonstrating the tool's impact on critical compliance tasks.
6Impact on Team Velocity
Internal code reviews have become noticeably faster, as reviewers focus on design rather than catching mechanical errors. Multi-file refactors, once considered quarterly events, are now a normal part of every sprint. Additionally, new Java engineers can reliably reach a meaningful first pull request within one or two days of joining the team.
7Audit and Assessment Support
The IDE's history tracking has simplified the evidence-collection process for ISO 27001 audits and CMMI assessments. By maintaining a clear record of code changes and refactoring operations, the team provides auditors with necessary documentation more efficiently. This capability reduces the administrative burden typically associated with maintaining compliance in a regulated healthcare software environment.
8Future Growth Strategy
Omi Health Tech plans to expand its product team from 10 to 20 engineers by the end of 2026. As they integrate more FHIR resource handlers and address future compliance needs, they intend to keep IntelliJ IDEA as their daily driver. The company focuses on twelve-month growth windows rather than long-term, abstract slogans.
