About me

Hello! I'm Tom, a Principal Software Engineer and Software Architect at Medidata, based in London.

I lead engineering and architecture across four core teams in Clinical Trial Financial Management. I work on payments, distributed systems, analytics, and platform modernisation, combining technical direction with hands-on development.

I work with product and engineering leadership to understand the problems we're solving and shape how we deliver them. I also helped establish a Scala guild to share engineering knowledge among Medidata's Scala engineers, and have spoken at London Scala meetups and delivered training across Medidata's R&D department.

Selected work

Across my roles at Medidata.

• Patient and site payments

  Led architecture and engineering for both product suites, coordinating delivery across teams and services and integrating third-party payment systems.

• Cost generation

  Designed and built a near-real-time system that turns clinical trial data into payments when contractual conditions are met, with retrospective cost generation and self-correction.

• Patient mobile integration

  Led integration with myMedidata so patients can manage payment preferences and tax information, and see payment amounts and timing.

• Reporting and modernisation

  Built a unified Snowflake reporting platform across financial management products. Led legacy product migrations onto the Medidata platform and broke monoliths into more scalable components.

• Engineering practices and AI

  Helped improve the software development lifecycle and delivery times, and worked on an early GraphQL API prototype. I'm also contributing to AI-based extraction of data from clinical sites' PDF invoices to reduce payment administration.
