Independent Builder - Product Experiments + Engineering

I turn lots of ideas into working products.

I have more ideas than time, so I prototype fast, ship what works, and keep refining. Projects like Charivo, LiveClaw, and Charaloom are part of that process, alongside tools, apps, and experiments across web and desktop.
