Full-Stack Developer (React Native / NestJS)

Contract / Part-Time – Ongoing Support & Refinement

We are seeking an experienced Full-Stack Developer to support and refine an existing production mobile application for a high-end, security-sensitive mobility platform operating in multiple regions.

The application has already been developed and handed over by a third-party agency. The role is focused on stabilisation, bug fixing, refinement, and ongoing technical support as the platform operates and evolves.

This is not a greenfield build. It is a hands-on role for someone confident stepping into an existing codebase and taking ownership of reliability and performance.

Responsibilities:
- Review and understand an existing production codebase
- Identify, diagnose, and resolve bugs across frontend and backend
- Improve application stability, performance, and reliability
- Support live operations with responsive fixes when required
- Make targeted refinements to existing functionality
- Ensure payment flows (Stripe) are robust and error-free

Work directly with the founder in a fast-moving, low-bureaucracy environment
