Eight years building where mistakes are expensive: healthcare apps serving millions of patients, Bluetooth locks where a bug fails a door, bootstrapped startups where the wrong stack burns the runway. Engineer, founder, consultant — whichever your problem needs. If it's real, I'll find the version worth solving and build the thing that solves it.

How I think

Useful beats impressive. Features must work at 3am, not just in the demo.

Small, reversible bets beat big, right ones.

Building is table stakes — knowing what to build is the craft.

Founding Partner Xccessor Innovations LLP

Engineering for founders whose runway is the product — every stack choice priced against survival.

More

Building software for bootstrapped founders who can't afford to get the stack wrong. Chose technologies based on cost efficiency, not convention — because runway is the product. Most didn't launch. That's the job: give every idea its best shot.
