This role will be responsible for shipping feature improvements, reducing technical debt, strengthening backend and API reliability, and helping move the development workflow into a properGit-based version control process.
The ideal candidate is comfortable working acrossmobile, backend, and infrastructure workflows, and can bring structure to an existing codebase while continuing active product development.
Key ResponsibilitiesMaintain and improve an existing Android application written primarily inJava/Kotlin
Support and enhance backend services and the API layer built aroundPHP and MySQL
Review and improve app-to-backend integrations, including:
authentication
messaging
subscriptions
profile management
related user flows
Refactor legacy code where needed to improvemaintainability, performance, and reliability
Identify and document backend endpoints, business logic, and system dependencies

repository organization
branching strategy
pull requests
commit standards
release practices
Migrate code currently managed outside proper version control into Git without disrupting ongoing development
