I build practical AI automation that streamlines business processes and removes manual work. With a strong backend engineering background, I wire LLMs, APIs and workflow tools like n8n into scalable systems for data processing, content generation and intelligent task automation. Every project has to pass one test: does it give someone their time back?

THE ONLY TEST THAT MATTERS

Does it give someone their time back?
