01 Mobile game development

Ninja Ducks
vs. Pirate Pigs

I led the development on Koko’s in-house mobile game: a side-scrolling level-based runner with objectives to complete, weapons and boss encounters, released in two parts depicting both factions in the Ninja Ducks vs. Pirate Pigs war.

My mobile-app work includes store-published projects with monetisation, analytics and in-game advertising.

02 CMS administrator & QA · staff training tool

Range Knowledge
on the Go

IKEA

I managed CMS product catalog staging and carried out QA for IKEA’s global staff training app, covering 500+ items across multiple languages. I tested employee journeys and ran exploratory checks across devices using BrowserStack.

My checks uncovered data persistence issues in the CMS, missing localisation copy, broken avatar graphics, and leaderboard display bugs. I worked directly with developers to resolve core saving and visual defects.

Ingesting and formatting 500+ product records, diagnosing data-saving defects with developers.
Quiz production
Structuring question sets, answer logic, and paired product imagery across training modules.
Localization & assets
Staging multi-language copy decks and verifying modular avatar sprite combinations.

03 Browser game development

Metrognome Dash

Metrocentre

I built this side-scrolling endless runner in Construct 3, featuring Metrocentre’s gnome mascots. As the player’s score increases, the game speeds up; their best score is saved locally and shown in the game.

I created the competition entry form on the game-over screen and connected it to backend APIs to submit players’ details for a prize draw. Artwork and backend services were part of the wider team’s work.

04 QA · web campaign

Trainline ×
Domino’s Trainthru

I tested the order journey, confirmation emails for customers and the client, and the accuracy and readability of order exports.

After following the main customer journey, I worked through a Google Sheets checklist and explored less obvious paths. I also leveraged AI tools to help map edge-case user journeys and expand test scenarios. During the live campaign, I monitored WooCommerce orders and stock.

Issues I found

Android landscape
Homepage content and copy became compressed.
Booking flow
A specific Terms and Conditions link failed here, despite working elsewhere.
Product descriptions
Some descriptions did not match the product being viewed.

My QA approach

From the brief
to the final checks.

  1. Start with the brief

    I turn a simple development brief into practical progress, working with animators and illustrators and keeping questions ready for project reviews.

  2. Organise the checks

    For QA, I create project checklists and useful Google Sheets trackers, or report defects in Jira. Coverage includes real devices, browsers and responsive layouts.

  3. Investigate and follow through

    I prioritise blockers, explore overlooked scenarios and work with developers on defects, retesting and regression checks. I report when a build is ready for review.

Illustrative Trainthru Jira board: booking links, Android landscape, product copy and order checks. Sample tasks and statuses, not an original ticket record.
