Work History

Director + Software Engineer

MASSLESS LTD.
Freelancing since 2016. Founded MASSLESS LTD in May 2021.
Remote, UK

I utilise my problem solving abilities, technical and creative and communication and leadership skills to build bespoke software solutions.

I communicated professionally and effectively with 30+ smaller start-ups and individual professionals to provide invaluable digital experiences.

For a recent client in 2025/26 I implemented cloud synchronisation via AWS Amplify for the backend with DynamoDB for the database, and generative AI for automatic cyber security threat modelling.

I worked from junior level, mid then at senior level, including experiences as a team leader, to bring projects from conception to launch.

For example in 2020 I was the solo engineer for an award winning project for an independent professional who hired me for their website development needs https://kirkwhayman.com which won 5+ SOTD (Site of the Day) awards on awwwards.com and earned me over £12,000 across 2½ months.

Front-end Engineer

March 2023 - November 2023 (9 months)
Remote

This was an opportunity which strengthened my Front-End engineering abilities, and the daily asynchronous communication along with helpful feedback helped increase my professional communication skills.

Utilising Next.js, React, GraphQL, Storybook and other technologies I worked on unique technical challenges, built components and pages, and wrote automated tests for the start-up - solving over 120 unique tasks and helping to overcome tasks marked as "blocked".

Software Engineer

DRPG
October 2020 to August 2022 (1 year 11 months)
Remote

I debugged and optimised a 3D web app, a winter wonderland celebrating 40 years of DRPG, taking the FPS (Frames Per Second) on smartphone devices from 2-3 FPS to 30-60 FPS. I also implemented a performant falling snow effect into the wintery scene, containing thousands of animated snow flakes.

I developed the Jaguar C-Type customiser tool with support from a junior engineer. Jaguar received over 8 customers for the C-Type continuation via the customiser app. DRPG earned an estimated £48,000 for this 1½ month project based on the £1600/day statistic I was shown.

I drove development on a 3D virtual events and conferencing web-app including implementing video projections onto 3D surfaces, bringing the virtual environment to life and an immersive, engaging experience.

Frontend Developer

Zengenti Ltd.
April 2019 - April 2020 (1 year)
In house - Ludlow countryside

This was an opportunity to work together as a team of engineers and UI/UX designers on 6+ websites for various councils and universities in the UK.

I informally mentored a junior developer, helping them become more independent, as they were sat next of me - and I proactively helped them get un-stuck on technical challenges.

My job involved improving the quality of the react/redux, front-end codebases, taking care to ensure the UI worked properly for screen-readers and people with accessibility considerations such as people with colour-blindness.

Express KCS
June 2018 - April 2019 (11 months)
In house - Milton Keynes countryside

This was my first time working in a small team of designers and developers, where I also learnt how to use JIRA and Git for daily use.

I implemented a modular i18n solution into the React codebase, using Locize for translators, and wrote lots of mocha tests.
