What we deliver
An application’s launch is the start of its working life, not the end of the work. Libraries publish security fixes, runtimes reach end of support, browsers and mobile operating systems change, integrations alter their APIs and users find defects that testing missed. Twara Technologies takes on the continuing engineering responsibility for business applications, keeping them correct, secure and current, and improving them steadily within an agreed plan.
Typical scope
- Web applications, customer portals and internal business systems.
- Mobile applications for Android and iOS, including updates required by app store policies.
- APIs, back-end services, background jobs and integrations with ERP, CRM, payment and messaging providers.
- Databases: schema changes, query tuning, data fixes and housekeeping.
- Build and deployment pipelines and hosting configuration related to the application.
- Second- and third-line support for issues raised by your users or help desk.
Technologies we work with
We maintain applications built on mainstream stacks, including React, Angular and Vue on the front end; Node.js, Python with Django or FastAPI, Java with Spring, PHP with Laravel, and .NET on the back end; Flutter, React Native, Kotlin and Swift for mobile; and PostgreSQL, MySQL, SQL Server and MongoDB for data.
Keeping runtimes on supported versions is central to the work. Two examples show why it needs planning:
- Node.js advises that production applications should only use Active LTS or Maintenance LTS releases. Each major version eventually leaves support, so upgrades have to be scheduled rather than left until something breaks.
- PHP supports each release branch with two years of active support followed by two years of critical security fixes only, after which the branch reaches end of life.
Frameworks and mobile platforms follow their own lifecycles too. We keep an upgrade roadmap so these changes arrive as planned, manageable steps.
How we approach it
- Onboard. Obtain access, confirm we can build and deploy from source, review architecture and code quality, and record known issues and risks.
- Stabilise. Address urgent items first: unsupported components with known vulnerabilities, missing backups, failing builds or absent monitoring.
- Run the plan. Handle incoming issues by priority, release fixes through a controlled pipeline, apply scheduled updates and deliver small enhancements.
- Prevent recurrence. Each significant defect gets a regression test, and recurring problems are traced to their underlying cause.
- Report and plan ahead. Periodic reports cover work completed, system health, upcoming end-of-support dates and recommended investment.
Quality and security
- Every change is reviewed. Code review and automated tests apply to fixes as much as to new features.
- Controlled releases. Changes move through test and staging environments before production, with a rollback route.
- Dependency hygiene. Automated tools such as Dependabot or Renovate flag outdated and vulnerable packages, and we apply updates on a defined schedule. Our approach to urgent fixes is described under security updates and patching.
- Secure coding. Fixes and enhancements are checked against common weakness categories in the OWASP Top 10:2025.
- Access you control. Individual accounts for our engineers, granted and revoked by you, with production access limited to those who need it.
Signs an application needs a maintenance plan
- Releases depend on one person who knows how to build and deploy the system.
- Framework, runtime or library versions are several releases behind, and upgrading feels risky.
- The same kinds of defect keep returning after being fixed.
- Users report problems through informal channels, and nobody can say what has been fixed or when.
- App store, browser or operating system changes have broken features with little warning.
- Documentation is missing, out of date or held on one person’s laptop.
If several of these sound familiar, an onboarding assessment is a low-risk first step. It produces a clear picture of the application’s condition and a prioritised list of work, whether or not you go on to a full maintenance plan with us.
Engagement options
- Retainer plan: a defined monthly capacity for fixes, updates and small enhancements, with unused-capacity rules agreed up front.
- Managed application service: Twara Technologies takes full responsibility for an application under a maintenance plan with agreed priorities and coverage.
- On-demand support: for stable applications that need occasional fixes and upgrades.
- Transition support: a structured handover from another vendor or an internal team, followed by any of the above.
