πΌ Professional Highlights (πsarab.tech)
Lead Mobile Engineer | Feb 2024 β Present
- Architecting Banking Systems: Leading the design of public banking apps using complex financial system modules.
- Production Ownership: Managed full App Store & Google Play publishing lifecycles, resolving complex compliance issues.
- Leadership: Conducting technical interviews, mentoring interns, and establishing structured error-handling strategies.
- Quality: Enforcing separation of concerns and maintainability through continuous refactoring.
The code I write today should be maintainable 5 years from now.
- Security is not optional: Especially in banking, it is the foundation, not a feature.
- Architecture before features: Scalability starts with a solid blueprint.
- Refactor when others stop: Clean code is a journey, not a destination.
- Ship fast. Maintain clean.
