A cyberpunk cityscape at night where towering neon-lit server stacks form skyscrapers, with streams of glowing code flowing through the streets like rivers. In the foreground, a lone figure in a hooded jacket uses holographic tools to surgically extract corrupted, flickering red data clusters from a massive crystalline structure representing a codebase. The corrupted sections transform into clean, brilliant blue light as they're repaired. Rain falls through purple and cyan atmospheric haze, reflecting off wet surfaces. Drones carrying diagnostic equipment hover nearby, their lights scanning the digital architecture for imperfections.
