Hi! I'm Kfir Gisman. I tackle software engineering challenges as if solving complex puzzles, leveraging my engineering mindset. My forte lies in translating human language requirements into high-level, robust projects, drawing on extensive experience in data analysis, security research, and software engineering. Having worked in successful startup and large corporations, I seamlessly integrate diverse approaches into modern project workflows. Moreover, I share insights on various topics through my Medium blog.
