01 / ABOUT ME
Complex problems.
Clear thinking.
I work where architecture meets implementation: turning ambiguous problems into systems that are reliable, efficient, and easier to evolve.
My career has taken me from Linux messaging servers and embedded multimedia to Windows internals, graphics drivers, low-latency trading, and global data-center capacity planning. The common thread is understanding how a system really works, finding the constraint, and simplifying the solution.
Most recently, at Google, I led technical direction for a capacity-optimization planning engine. Before that, I helped build engineering teams at Omnissa, shaped compliance architecture at Atlassian, and improved reliability and recovery in Adobe Illustrator.
I stay close to the code while mentoring senior engineers, connecting teams, and using operational evidence to decide what matters next.
