Hi, I'm Jacob

Technical Lead, Fractional CTO, Engineer

…I founded Sancho Studio to help teams make excellent technical decisions. With 10+ years of experience across security, cryptography, systems, manufacturing, and payements.

I built end-to-end encrypted video calling at Zoom Video and cryptography products at Keybase.

What I can do for your business

Technical Leadership: I help engineering teams deliver better software, adopt and perfect AI coding agent, and system design.

Software Architecture: I help teams that have outgrown their first codebase but haven’t yet hired the staff engineers to fix it.

Best path is through Sancho Studio. If you want to talk about anything else, find me on LinkedIn.

nice words from clients
Jacob's insightful analysis and clear communication moved the needle on multiple projects that were made better because he was on the team.
Joe Greenheron Technical due diligence partner
His ability to quickly grok and translate highly technical problems to every level of stakeholder — while working directly with us on effective remediation — proved quite valuable for our engineering team. I would recommend Jacob's technical services to anyone seeking an engineering partner or lead-level employee.
Nicholas Arnold Technical lead, former client
Jacob is truly an extraordinarily sharp and quick mind. In terms of technical acumen, laser focus, and architecture and engineering chops, you could hardly do better than work with him.
Greg Sadetsky Founder, former client
Jacob refines requirements rather than just executing on tickets — pushing back on the spec and tightening the design before any code is written. He gets up to speed with unfamiliar code remarkably quickly, making real contributions within days.
