Sure, shifting from QE to Dev demands learning new skills with real-world coding practice. Embrace patient effort, always look for opportunities to apply new skills at work. Network for insights and opportunities, preparing for critical topics like data structures, algorithms. It's doable. Stay focused, good luck.

IMO you need to learn DSA, Design Patterns, Architectural Concepts, etc.
