Technical Challenges & Solutions
A. Rapid Skill Adaptation (The Swift Challenge)
Facedwitha3-monthdeadline,theprojectrequiredanimmediateiOSdevelopmentoverhaul.IsuccessfullytransitionedintoiOSdevelopmentbymasteringSwiftsyntaxandApple’sarchitecturalpatternswithinoneweek.ThisrapidadaptationenabledmetotaketheiOSapplicationfromalegacystatetoafunctional,high-performanceMVP,demonstratingmyabilitytomasternewtechnologystacksunderpressure.
B. Data Migration & Architecture (Zero-Data-Loss)
