Contact: or (including recommendations)

Talented and experienced technical leader, manager, mentor and coach; with a passion for diversity, inclusion, accessibility and enabling others. Looking for a balance between management, technical architecture and leadership, and hands-on coding. My goal is to help drive a positive change in those around me; through coaching, technology and awareness. A literal-minded individual who thrives with clarity of communication, and in an open and inclusive workplace culture.




Head of Engineering, PRELOADED (April 2023 - May 2024) (Redundancy)

PRELOADED’s core values are we play with purpose, we are curious, we are greater than the sum of our parts, we prioritise a work/life balance and we believe in accountability and trust. I believe that during my tenure at PRELOADED I have embodied those values, and made a difference to both the Engineering team, and the wider team as a whole. I am also an advocate for diversity and inclusion.

As Head of Engineering I am responsible for ensuring that the Engineering team is set up for success - through leading, nurturing and developing the individuals in the team, and ensuring the right level of studio-wide Engineering Governance and processes are in place to successfully deliver a broad range of projects. I am incredibly proud and passionate about bringing Technical Excellence to everything I do - across projects, processes and pitches.

From a team leadership perspective, I make sure that the Engineering team are supported, and have a voice. They know that I have their backs and this makes them feel empowered. My management philosophy is one of trust, empathy and clear communication, along with a healthy dose of radical candour. I encourage autonomy, whilst also providing structure and support where needed; tailored to each individual’s needs.

I have been responsible for overseeing the successful deployment of several projects during my tenure, including Wonders: Pyramids of Giza (An educational UEFN Map, in collaboration with Epic Games), Andrex’s GoTime app (Unity mobile app, for Kimberley-Clark), and LEGO® Cat Island Adventure (UEFN Map, in collaboration with LEGO System A/S).

Head of Engineering, Poplar Studio (September 2020 - March 2023) (Redundancy)

    Tech Lead (September 2020 - September 2021)

At Poplar Studio, learning was at the core of everything we did, and we were passionate about educating people about Augmented Reality (AR). Our project management tools and talent cloud made it easy for brands to create and deploy AR and 3D experiences across all channels. We also had a lot of fun trying the latest immersive technologies and we wanted to share that fun with everyone.

I was part of the Leadership team throughout my tenure, which included attending board meetings and presenting to investors (and applying for R&D Tax Credits). I was responsible for building, managing and coaching the engineering team; and for technical architecture and direction, in direct liaison with the product team. I was also responsible for shaping and maintaining an inclusive company culture - changing behaviours for the better, and inspiring others to share and be themselves.

I was hand-ons with innovating, coding and managing tech debt and infrastructure; building and managing 5+ SaaS platforms from the ground up. Our work enabled brands/agencies to submit briefs through a simple interface; to manage projects with a network of creators through our platform; with a CMS to enable virtual try ons of various products including rings, watches, furniture etc. at scale, which could be integrated through a single line of code.

Director, Jo Carter Ltd (April 2019 - June 2021)

    Senior Software Engineer - (February – August 2020)

    Worked with several Symfony versions (3.4, 4, and 5) on multiple projects at MyBuilder. Involved in both upgrading legacy code and writing new functionality, both working solo and pairing with other developers.

    These included: MyBuilderPlus (event-driven backend, CQRS, Symfony 5 with messenger component, DDD, Docker, Lambda and Bref; and a Symfony+Twig frontend consumer site); The MyBuilder site (Symfony 3.4), with additional microservices e.g Push Notifications, (Symfony 5 + Bref); and the Quote Tool (Symfony 4 API Write Model for a React Client app, with events and commands). CodeMentorX Certified Developer and Peer Technical Interviewer (May 2019 - Jan 2020)

    Conducting technical peer interviews as part of the vetting process for obtaining verified status on the service.

    Consultant Senior PHP Developer at J Sainsbury, Daemon Solutions (May – December 2019)

    Via the technology consultancy firm Daemon Solutions, I worked with the Sainsbury’s Food to Order team on their website, which consisted of a collection of Symfony 4 microservices (used by their Node and React applications) and a legacy Symfony 3 monolith. I was involved in integration with internal (third party) APIs, logging and auditing, code gardening, documentation, planning and deprecation of old code. This included upgrading the monolith to the latest version of PHP and Symfony 3; and rolling out a whole range of code improvement tools across the microservices (PHPStan, Infection/ Mutation), in addition to improving overall coverage and code quality. I really enjoyed collaborating with the team, including helping mentor an apprentice developer.

Fifty Penguins in Fuzzy Socks Ltd (November 2017 - April 2019)

    Freelance PHP Developer, Babylon Health (March - April 2019)

    Freelance Senior Software Developer, Wellcome Trust (March - December 2018)

    Part of the team responsible for the development of the Explorify website (science for primary school teachers). During my time there we refactored the majority of the codebase (PHP, frontend and the database), added additional automation for testing and QA, and upgraded the site from Symfony 3 to 4. Day to day work included code reviews, adding new features, cleaning data, maintenance and as much code gardening as I could squeeze in. I also contributed back to several of the open source bundles we used.

    I was brought in as a full-stack developer, so I also worked with the team on adding automated testing using Chai, Mocha, Cypress and Nightwatch (with Browserstack); and helped refactor the frontend code (with an emphasis on accessibly and UX) and developed new features (using Webpack, Javascript and SCSS/CSS). We also added in a stats dashboard, split testing (A/B), tracking and monitoring so we could see how our new features improved the user experience.

    Consultant Engineering Manager, Onlicar (November 2017 - March 2018)

    Fifty PIFs was brought in to evaluate the technical process at Onlicar and help streamline it. I worked with the existing team to add in monitoring for their services, update the documentation to understand how all the systems worked together, and introduced the developers to automated testing to make their systems more resilient and add oversight to increase efficiency. I also code reviewed and QA’d new python code for a system upgrade by our internal team.

Engineering Manager, MOO (June 2017 - November 2017)

Joint Development Team Leader, The Mill (November 2014 - June 2017)

My team and I mainly worked on internal projects, which included developing a custom CRM; a custom solution for optimising the quoting pipeline for our 2D, 3D and design departments; an applicant tracking system with accompanying candidate microsite; an online annual review system for HR; and other internal integration projects. We also worked on a number of large external client projects, mainly on integrations and APIs for mobile applications and games, with some branching into VR.

I was directly responsible for managing several members of the development team, including coaching, mentoring and career path development. I was heavily involved in the recruitment process for new team members; through tech tests, interviews and hiring. I was part of the diversity and inclusion network within the Mill, with a focus on improving the hiring pipeline.
