ABOUT ME

Experienced software engineer with a passion for Web Development.

I've spent 12+ years at FactSet as VP Principal Software Engineer building enterprise platforms serving 10,000+ investment professionals globally. I specialize in solving the exact challenge Series B SaaS companies face: platform fragmentation as teams scale from 30 to 80+ engineers.

My career focus is helping scaling companies architect orchestration platforms that eliminate duplicate work, reduce integration time from weeks to days, and enable teams to ship faster - without big-bang rewrites that kill velocity.

I bring FinTech compliance rigor (12 years) and Defence security standards (2.5 years) to every engagement. Available 15-20 hours/week for strategic architecture advisory.
