• Reduced technical debt (tracked through code reviews/refactoring).
• Positive feedback from peers and product stakeholders.

Interview Process:

• Initial Phone Screen
• Video Interview with Pavago Recruiter
• Technical Assessment (e.g., build a small feature end-to-end with API + UI + test coverage)
• Client Interview with Engineering/Product Team
• Offer & Background Verification
