// ACHIEVEMENTS UNLOCKED

IN PROD

Generative AI in a regulated environment

Architecture and development of a RAG and multi-agent platform for clinical-trial research in rare diseases, in the pharmaceutical sector.

-70%

AWS costs

By optimising the architecture and cloud resource usage, with continuous operational review.

REAL TIME

Payments and transactions

Stripe, Google Pay, Apple Wallet and restaurant POS: flows where a failure costs money.

INDUSTRIAL SCALE

Industrial 5G

Cloud orchestration to roll out 5G connectivity at industrial scale and automate the SIM lifecycle.

// SELECT WORLD
