Founder and CEO of Routespring · Co-founder and advisor to Up Robotics

I build systems that have to work in the real world.

Software for operationally complex industries — payments, healthcare, and now travel — the exception-heavy workflows and fragmented coordination that most software quietly gives up on.

Building now

Routespring

Founder and CEO · 2020–present

Software for corporate travel and airline crew operations — booking, payments, hotel operations, disruption handling and reconciliation. The current focus is using AI to automate the exception-heavy operational work that has always fallen back to phone calls and manual coordination: agents that call hotels, rebooking that resolves disruptions in minutes, software that does the services work itself.

Series · 7 parts

Company-Building Under Real Constraints

Concrete decisions from operational software companies — customer concentration, automation readiness, exception handling, services, enterprise risk, and what exits do and don't teach.

  • Pivot gates

    How founders can distinguish a slow strategy from a broken premise before sunk cost makes the decision for them.

    Building Routespring

  • Routing optimization isn't a shortest-path problem

    The hard part of flight routing was never finding the cheapest itinerary. It's that 'cheapest' and 'best' are different questions, and one of them is a hard rule while the other is a matter of taste.

    Thinking in Public

  • The first question in any outage: whose system is it?

    Most production failures in integrated systems aren't yours or theirs. They're the handoff between the two, and that's exactly where nobody looks first.

Selected projects

Policy-aware flight search

Prototype

An MCP server that searches Google Flights, evaluates each option against a corporate travel policy, and ranks compliant results by traveler preference — an agent-native travel experience that keeps explicit policy and payment boundaries.

AI pillbox monitor

Student project

A Raspberry Pi and on-device computer-vision system, built with an Up Robotics student, that reads which of 21 pillbox cells still hold medication across seven days and three daily periods.

Co-founder and advisor

Up Robotics

A hands-on robotics and engineering program for young students. Not my day-to-day work — I help with strategy, technology and the occasional problem that needs more adults than children.

Off Duty

Away from the company: coaching robotics, over-built home infrastructure, and ranked lists of the films and shows I actually think about afterward.
