Services
Engineering across the full product lifecycle
From a new product build to a difficult legacy system, Lehua Logic can take ownership of the work, reduce uncertainty, and move the project toward a maintainable production result.
Mobile and Cross-Platform Apps
Mobile applications built with React Native, Capacitor, native integrations, and platform-specific code where performance or device access requires it.
Relevant technologies
- React Native
- Swift
- Java
- Capacitor
TV, Device, and Embedded Software
Applications and integrations for Apple TV, Roku, Linux devices, shipboard environments, and systems that must operate reliably with limited or intermittent connectivity.
Relevant technologies
- Apple TV
- Roku
- Linux
- MQTT
- Embedded integration
Backend and Distributed Systems
Backend services, messaging, networking, data flows, deployment architecture, and production integrations for systems that need to remain stable under real-world conditions.
Relevant technologies
- Node.js
- RabbitMQ
- MQTT
- PostgreSQL
- NGINX
- Docker
Modernization and Reliability
Investigation and improvement of aging applications, fragile deployments, performance bottlenecks, difficult build pipelines, and undocumented production behavior.
Relevant capabilities
- Legacy modernization
- Debugging
- Architecture
- CI/CD
- Production support
Selected experience
Experience with software that has to work in the real world
Some prior work was completed under client confidentiality. Examples below describe the engineering scope without exposing proprietary details.
Shipboard and Guest Applications
Maintained and extended applications used across cruise and hospitality environments, including guest-facing experiences, account and invoice functionality, and onboard operational systems.
Key challenges
- Intermittent connectivity
- Long deployment cycles
- Hardware constraints
- High reliability requirements
Mobile and Living-Room Platforms
Built and supported applications spanning mobile devices, Apple TV, Roku, and cross-platform interfaces, including native integrations where platform-specific behavior mattered.
Key challenges
- Cross-platform consistency
- Video playback
- Native bridge integration
- Device-specific behavior
Distributed Messaging and Infrastructure
Worked with multi-node messaging systems, MQTT connectivity, NGINX networking, containerized deployments, and service integrations operating in constrained production environments.
Key challenges
- Reconnection behavior
- Message reliability
- Network boundaries
- Operational visibility
Legacy Ownership and Modernization
Took responsibility for long-lived applications with limited documentation, traced production behavior across multiple systems, and delivered changes without destabilizing critical workflows.
Key challenges
- Incomplete documentation
- Legacy dependencies
- Production debugging
- Incremental modernization

Approach
Direct, practical, and accountable
01
Understand
Clarify the business need, current system, constraints, stakeholders, and definition of success before prescribing a solution.
02
De-risk
Identify unknowns early through code review, system investigation, prototypes, architecture planning, or targeted technical experiments.
03
Build
Implement in maintainable increments with clear communication, sensible documentation, and attention to production behavior.
04
Deliver and support
Deploy, validate, transfer knowledge, and remain available for stabilization, iteration, or continued ownership.
You work directly with the engineer doing the implementation. There is no account-management layer between the problem and the person solving it.
About
Senior software engineering without the agency overhead
Lehua Logic LLC is an owner-operated software consultancy based in Honolulu, Hawaiʻi. It was formed to provide companies with a straightforward way to engage experienced software development services from Hawaiʻi.
The principal developer brings more than 13 years of professional experience across consumer applications, cruise-line platforms, shipboard systems, mobile applications, streaming-device software, and backend infrastructure.
The focus is not simply producing code. The work includes understanding unfamiliar systems, tracing failures across application and infrastructure boundaries, making careful architectural decisions, and leaving software easier to operate and maintain than it was before.
- Own the outcome
- Prefer maintainable solutions
- Communicate uncertainty early
Engagements
Ways to work together
01
Project Development
For a defined application, feature set, integration, or modernization effort.
02
Embedded Engineering Support
For teams that need an experienced developer to join an existing workflow and contribute directly.
03
Technical Investigation
For difficult bugs, production incidents, architecture questions, legacy systems, and projects that need clarity before implementation.
04
Ongoing Application Ownership
For businesses that need a dependable technical partner to maintain, improve, and support an important system over time.
