Explore AccountabiliBuddyI’m Ruk. I like the part where an idea becomes something you can use.
My background is in enterprise technology sales, where the conversation starts with what someone needs to accomplish. Building software lets me follow that question all the way into the product.
At Checkmate Labs, I own the product direction, design, development, and release. I use AI development tools throughout the process and stay responsible for the choices: what belongs, what gets simpler, and what is ready to ship.
The work ranges from a tool I can use during a presentation to a game that gives friends a reason for a rematch. That mix of practical need and playful instinct is the studio.
