    • Fast Learning & Self-Driven Growth

      Fully self-taught engineer with no formal CS degree who has independently mastered web, mobile, and native development across multiple stacks. Consistently picked up unfamiliar technologies to meet project needs — from Swift and SwiftUI to Flutter and Electron — and contributed meaningfully from day one.
