Work history

Through my most recent roles, I’ve developed my skills as a technical writer working with AI, APIs, SaaS, and fintech.

I have experience building documentation functions from scratch, including building the docs-as-code stack, establishing relationships with stakeholders across businesses, and implementing AI-assisted workflows to automate tasks well-suited to it.

This page provides a summary of the sorts of work I’ve done at each employer. You can find more detail about projects I’ve worked on in the Portfolio section.

Section titled “Navro ”

I worked for Navro as their lead Technical Writer, reporting directly into the Chief Product Officer.

Navro is a fintech company that provides global payment curation. They have partnerships with a variety of banks and route a given payment through the best possible infrastructure.

Users of the Navro documentation could either be technical or less technical. As such, I implemented site-side filters that readers could use to adjust the information architecture to suit their needs.

I worked as the sole technical writer at a scale-up, handling all aspects of documentation with other responsibilities too.

Working at a scale-up, a priority was transforming basic documentation into something mature enough for the enterprise contracts the company was signing.

While I worked at Navro, the strategy was to do more with less in order to extend runway and increase profitability as quickly as possible. This meant that I automated as many parts of the documentation as possible and used LLMs to aid in drafting content – so I had capacity to write the documentation that mattered most.

Alongside documentation, I also drafted release communications and implemented a changelog, alongside other achievements.

  • Managing the infrastructure of the documentation site (hosted through Redocly), including:
    • Maintaining a user list and permissions and applying role-based access control so this drove what readers saw.
    • Styling the site, designing icons, diagrams, CSS, and mermaid/plantUML diagrams.
    • Building scripts in the docs-as-code repo to automate updates based on the latest to an API (via hundreds of reusable MarkDoc snippets).
    • Creating client-side tools (no uploaded data) hosted on the docs site that readers could use to filter and create templated CSVs from complex JSON sources.
  • Overhauling a bare bones suite of documentation into something robust that clients loved, including:
    • Building deep knowledge of the product then using that to create an intuitive information architecture (IA) for the docs.
  • Developing relationships with stakeholders in Product, Engineering, Customer Success, and Commerical to ensure all documentation needs were captured.
  • Building internal dashboards/webapps to ensure that less technical colleagues all had access to up-to-date data.

Section titled “TrueLayer ”

I worked for TrueLayer as a Senior Technical Writer.

TrueLayer is a fintech company that develops payments APIs and user interfaces based on the ‘open banking’ regulations in Europe.

The main users of the documentation were both internal and external people who were integrating with TrueLayer’s APIs. This involved SMBs through to large corporate clients.

I was the lead technical writer in a fintech startup of about 300 people with a $1 billion valuation.

In this position, I displayed autonomy and initiative, working in an ambiguous environment. I had to apply skills in information architecture, API documentation, and introducing organisational change.

I maintained the entirety of TrueLayer’s integration documentation and API reference, including procedures, landing pages, references, release notes and more. I also worked with developers, writing UX text and API specifications.

I mentored a junior technical writer and acted as the scrummaster of a small agile team.

  • Several refactors of the documentation IA as the number of pages grew over 3x. This addressed growing product complexity.
  • Created new quickstart guides, integration checklists, and REST API client collections. This reduced time to live for clients, boosting revenue.
  • Worked with staff engineers to develop an API specification monorepo. This automated publication, reducing overheads and keeping the reference up-to-date.
  • Achieved 1st and 2nd place in the two annual hackathons I participated in. This required wide product knowledge and presentation skills.
  • Improved the visuals of the docs site through HTML, CSS, and consistent Figma assets. This kept the site on-brand, and enabled more diagrams, flows, and HTML elements.

Anaplan logoAnaplan December 2018 - July 2022

Section titled “Anaplan ”

I worked for Anaplan as a Technical Writer.

Anaplan is a SaaS business intelligence company. Their product is spreadsheet-based and can be used by end users, but grows in complexity as the volume and types of data increase.

The documentation was used both by users learning the basics of the Anaplan product, and advanced users looking to optimise the memory performance of their models.

I was one technical writer in a Content Team of about 10 people in a fast ng post-IPO startup. The structure of the team changed several times.

When I started the role, we had editors who reviewed all of our content and provided guidance. However, this changed to a more flat hierarchy and we introduced a content technology team and other more specialised roles.

In this position, I worked as a ‘semi-embedded’ writer in multiple development teams based in London, York, and San Francisco. In practice…

  • A complete rework of our calculation function documentation (over 100 pages). This involved creating component-based templates that can be surfaced in the UI, developing a stakeholder review process, and onboarding several junior colleagues. The componentised content has now been surfaced in-product as a new feature.
  • An update of our API documentation suite. This included building Postman collections, reviewing existing documentation, and converting specs to API blueprint format.

Thomas Harrington logoBupa Global July 2016 - December 2018

Section titled “Bupa Global ”

I worked for Bupa Global as a Document Content Specialist for over a year. Before that, I worked there as a Customer Service Consultant.

Bupa Global is the premium international insurance of the British health insurance brand Bupa. As such, it has higher expectations around user experience and SLAs, alongside increased regulatory complexity. This meant that there was a large volume of operational documentation, with had to be clear and effective.
