Cydar Medical

Leading and growing the wider engineering team. Interface between business needs and technical delivery; architecture & strategy. Ownership of dev. process, improvement of the product. Driving value to achieve business goals and ROI.

Cydar Medical

Project & team leadership, development of various high-profile Cydar cloud components necessary to bring Cydar EV to the operating theatre with a good user experience. Team leadership plus larger project groups.

Cydar Medical

Implementation of a distributed compute system to bring a prototype 2D-3D registration system to clinical usefulness. Development of a PACS gateway to enable access CT scans inside the hospital network via the cloud.

Broadcom

Full SoC and PCI-E partition on Virtex 7 FPGA Clusters, 3x speed improvement to muxing hardware or emulation of SoC, dev of Cadence Palladium resource sharing system.

Broadcom

Vertex 7 FPGA cluster bring-up with pattern checking HDL. CI testing system for new SoC. Dev board design, stereoscopic camera add-on, automated testing system, lab + budget management, technical duties.

Cydar medical

Technical architecture and project manangement for a batch based follow-up CT scan transfer system to transfer tens of thousands of CT scans for later processing to enable end-to-end patient care.

Cydar medical

Project management and delivery strategy to deliver an improved planning tool for use with Cydar Maps

Cydar medical

Custom-designed remote control interface for in-theatre use. Involved the co-ordination of initial research, UX consultants, UI, hardware and the development of embedded firmware for a LoRa RF USB remote. Long range, decade battery life, low latency. Highly reliable, deployed worldwide.

Cydar medical

Auto-update system for deployment of edge-based software within the hospital such as in-theatre kiosk, case recorder and PACS gateway. Minimal-downtime deployments and remote troubleshooting. Architecture audited and penetration tested by NCC group. Hundreds of installs each with hundreds of updates – zero failures.

Cydar medical

Project leadership of the Cydar EV Deformation adjustment tool to increase update the anatomy within maps. This involved leadership of a team of 8 engineers to co-ordinate and prioritise work and deliver for commercial uplift.

Cydar medical

Implementation of a secure SAML2 SP enabling integration with hospital SSO running Shibboleth, Microsoft ADFS / Azure and others. Work to prevent attack vectors. Penetration tested by NCC group.

Cydar medical

Created an edge-deployed PACS gateway to automate the query & retrieval of CT scans (DICOM) from hospital PACS on behalf of clinicians using Cydar’s products. Strong concurrency/queuing model with real-time progress and self-update mechanism. In use since 2017 in 80+ hospitals reliabily transferring tens of thousands of scans.

Cydar medical

Content-addressable object-store built upon S3 and Redis to allow low-latency access to data referenced by SHA-256 digest. Intrinsic automatic de-duplication and integrity guarantees. Critical for Cydar’s patient data and real-time registration pipeline.

Cydar medical

As part of a challenge and business need to improve Cydar’s 2D-3D image registration performance, I designed a low-latency work-distribution system using Redis and a custom content-addressable storage system to reduce the registration time from 50 seconds to under 5 seconds.

Broadcom

A faster multiplexing system was required to increase core-clock frequency. I developed a new system involving source-synchronous clocking. The new design was capable of 4.5x SoC core clock improvement decreasing costs and increasing productivity 2x

Broadcom

2 daughtercard designs allowed a development kit to interface 2x CSI cameras with shared clock and a Sharp auto-stereoscopic 3D display. This required some investigation and defensive design as datasheets were not yet available.
