Preferred Experience

Domain Expertise: Background in Fintech, Trading, or Banking applications is highly prioritized.
Data Visualization: Experience with financial charting or graph libraries .
Legacy to Scale: Proven ability to refactor prototype code into hardened, production-ready modules.
What We’re Looking For
We need a developer with a strong ownership mindset who can quickly navigate and improve an existing, large-scale codebase. You should be comfortable balancing the speed of new feature development with the discipline required for deep cleanup and refactoring work.

Qualifications

Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.
Proven track record of shipping and maintaining high-traffic Flutter apps on the App Store and Play Store.
