About

Building systems that work for people

Hi, I'm Larna.

I’m a software engineer based in the UK, building full-stack applications and structured data systems using JavaScript, React, Node.js, Python and SQL.

My work focuses on accessibility, maintainable architecture, and designing software that remains usable in real-world conditions, particularly where users are managing complexity, time pressure, or cognitive load.

My experience prior to software engineering is in education leadership and digital learning design. That background strengthened my systems thinking, communication skills, and understanding of how information design affects usability and decision-making.

After completing an MA in Digital Education, I realised I particularly enjoyed designing digital products and wanted to learn software engineering so I could build systems from scratch, rather than relying on platforms with fixed constraints.

As I developed my engineering skills, I found I genuinely enjoyed the creativity, challenge, and satisfaction of building, testing, debugging, and iterating on products, especially when working to make them accessible and usable for the widest range of users possible.

Alongside continuing to work in education, I now build full-stack applications focused on usability, accessibility, and structured problem solving, applying testing, API integration, secure coding practices, and iterative delivery to create reliable, maintainable systems.

Work

Featured projects

A selection of full-stack applications and data-driven systems focused on usability, accessibility, and structured problem solving.

  • Culture Finder

    Event discovery and wishlist application that helps users search for cultural events, save promising options, and organise future plans.

    Problem

    Finding and keeping track of relevant events across different dates, categories, and venues can involve fragmented searches and unnecessary cognitive load.

    Engineering Focus

    External API integration, accessible interaction design, state and data flow, testing, error handling, and resilient empty states

    • Next.js
    • React
    • JavaScript
    • REST APIs
    • Jest
    • React Testing Library

  • Task Management API

    Backend API for structured task tracking and complex casework-style workflow management.

    Problem

    Manual task coordination and inconsistent tracking create inefficiencies and reduce reliability in complex, time-sensitive workflows.

    Engineering Focus

    API design, layered architecture, automated testing, input validation, error handling, secure coding, and maintainability

    • Python
