Codebase Modernization
- Refactor existing codebases and apply SOLID principles and Clean Architecture.
- Implement top security standards across both Android and iOS platforms.
- Focus on building scalable, maintainable, and sustainable mobile systems.
AI-Accelerated Engineering
- Use AI-assisted engineering tools such as Claude Code, OpenAI Codex, GitHub Copilot, and Cursor.

- Test-Driven Development (TDD)
- Unit Testing
- Integration Testing
- Ensure application stability and prevent regressions through robust testing practices.
Release Execution
- Drive the complete release lifecycle for a stable v1.0.

Ship v1.0
- Deliver the first production-ready version (v1.0) against a clear deadline.
- Take ownership of delivery and create real technical and business impact.
Build for Sustainability
- Focus on scalable, maintainable, and sustainable systems.
- Make technical decisions that support the long-term evolution of both mobile applications.
Own Decisions
- Take ownership of architecture, design patterns, and technology choices.
- Make independent technical decisions based on scalability, maintainability, security, and performance.
Document & Communicate
- Clearly document technical approaches, architecture, and key decisions.
- Communicate the reasoning behind technical choices and implementation approaches with the team.
What We Offer
- Opportunity to take end-to-end technical ownership of two core native mobile applications.
- Opportunity to modernize and shape production-grade Android and iOS applications.
- Work with modern AI-assisted engineering tools and workflows.
