Designed and led development of DAZN’s proprietary MSE/EME-based adaptive player (“Mercury”), replacing numerous open-source and native players with a single consolidated experience across all supported platforms (web, smart TV, consoles, set top boxes, dongles).

Designed proprietary ABR algorithms and resilience countermeasures leading to improvement of critical playback QoE metrics such as start time, rebuffering ratio, fatal errors, and average video quality for millions of customers. Algorithms were perpetually fine-tuned through data analysis and experimentation.

Monetized many legacy streaming devices lacking native ad-insertion support through the enablement of robust multi-period DASH support leading to a multi-million dollar increase in advertising revenue and contributing to DAZN winning the "Next Generation Advertising" award at the 2022 Video Tech Innovation Awards

Designed and led development of an in-house player testing framework (“FABRiC”), allowing automated functional player tests to run against simulated network conditions and test scenarios across cloud and lab-based pipelines.

Designed a release and deployment system ("ALib") based on semver contracts, allowing client library teams to deploy patch and minor releases autonomously, leading to a 5x increase in deployment frequency, and general improvement in health-checks across many teams

Architected and led development of an internal focus management library for use by all teams building TV application UI, resulting in the deletion of thousands of lines of application-specific focus management code that was polluting business logic across several codebases.

Re-architected DAZN's 2.0 client player architecture to enable high-decoupling and modularity, with the goal of scaling a single player codebase across upwards of 15 different target platforms (browsers, TVs, consoles, dongles, etc).

Removed a critical dependency on a third-party vendor in order to achieve increased control of architecture, quality of service, understanding, and cost saving.

Introduced TypeScript across the playback codebases and evangelised its usage across the wider technical team.

Enforced high coding standards and knowledge sharing through regular architectural stand-up sessions, mob programming exercises, extensive documentation and high code coverage across critical codebases.

Liaised with product and architecture team members to shape the product roadmap and high-level technical decision making.

Re-architected the playback deployment process with the goal of increasing frequency and granularity of deployment and removing external bottlenecks.

contributed to the rapid growth of the DAZN front-end teams from less than 20 to over 50 mid to senior-level engineers across three development centres in London, Leeds and Amsterdam, through technical phone screens, code-test reviews and on-site whiteboard interviews.

Designed and rolled out a condensed on-site code test exercise to reduce the drop off rate of candidates at take-home code test phase.

Worked closely with CEO and CTO to manage and lead execution of all product and UX work.

Architected, developed and maintained Colony's proprietary isomorprhic JavaScript framework "CortexJS", allowing stateful server-side rendering of single page applications in non-JavaScript server-side environments (e.g. .NET) via shared language-agnostic universal components. Concept was featured in the 2016 O'Reilly book "Building Isomorphic JavaScript Apps".

Architected, developed and maintained Colony's proprietary video player framework "CortexPlayer", enabling the creation of rich cross-platform video UI through a common abstracted API over a variety of plugin-free ABR and DRM video solutions (via MSE/EME) such as DASH/HLS/Widevine/Playready/Fairplay, and integrating with sender applications (e.g. Chromecast). As a result of this work, Colony was the first (and for over a year, the only) UK-based VOD platform able to provide plugin-free DRM playback in all major browsers.

Developed a JavaScript -> C# transpiler enabling the sharing of common application view models and view logic between front-end and back-end applications.

Implemented extensive documentation and testing.

Lead weekly design reviews.

Managed Colony's 2016 rebrand.
