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

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

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.

Cydar medical

Implementation of a secure SAML2 AP 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 50+ hospitals.

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.
