About Me

As a senior developer, I turn ideas into high-quality, usable software that creates real value for users and organisations. I focus on reliable features, mentoring, and leading problem-solving efforts while driving innovation with smart tools and AI. My side project PromptToForm, an infinite-canvas form & flow editor powered by Gen-AI, shows how I simplify complexity and deliver solutions that people can actually use.
