• Managing Director

  • Mar 2018 - Jun 2023

  Our company develops bespoke software applications, algorithms, and machine learning solutions for clients in the US, Europe and Asia. We specialise in remote condition monitoring and railway signalling applications, however we have also developed applications for fintech and commercial services providers where our experience with large datasets can be leveraged. We are experts in the following: Railway signalling equipment - We have a decade of experience working data from all types of wayside signalling equipment, including track switches, track circuits, relay interlockings, CBTC systems, OLE and more. We know their failure modes, how they are maintained, and the engineering processes associated with them, both in the UK and overseas. Python and the machine learning stack - We have developed all kinds of applications in Python, from proofs-of-concept using Tensorflow and Pandas, to full fledged customer facing web applications running on AWS serving thousands of users.
