Software & Product Development Services

• rocket_launch

  Product & MVP Development

  Turn an idea into a working digital product.

  Scoping what the first version actually needs to prove, then designing, building and launching it. The goal is something real in front of users, not a prototype that never ships.

  • System Design
  • React
  • Kotlin
  • Spring Boot

  Built:SwapFormat,QuickScan,ZenLife AI

• language

  Web Application Development

  Modern web applications, tools, dashboards and platforms.

  Web products that stay fast and maintainable as they grow — including work that runs entirely in the browser when that is the better privacy and performance answer.

  • React
  • Next.js
  • REST APIs

  Built:SwapFormat,CodeDepth

• phone_android

  Android App Development

  Android apps from concept through development and Play Store release.

  The whole path, not just the code: architecture, implementation, store listing, release and the updates afterwards. I have taken my own apps through this repeatedly.

  • Kotlin
  • Jetpack Compose

  Built:QuickScan,PDF Reader, Editor & Scanner,Ghost Notes

• dns

  Backend & API Development

  Java, Spring Boot, REST APIs, integrations and backend systems.

  Event-driven and service-based backends, integrations between systems, and the data layer underneath them. This is what I do professionally on airline platforms.

  • Java
  • Spring Boot
  • Apache Kafka
  • REST APIs
  • PostgreSQL
• architecture

  Product Engineering

  Feature development, architecture, performance and reliability.

  Working inside an existing codebase — shipping features, improving architecture, and making a system easier to run and change rather than rewriting it.

  • Microservices
  • System Design
  • AWS
  • Docker

  Built:PDF Reader, Editor & Scanner,Stitch Infinite

• insights

  Technical Consulting

  Evaluate an existing product, architecture or technical direction.

  A considered second opinion: reviewing an architecture, weighing a technical decision, or working out why a system is harder to change than it should be.

  • System Design
  • Technical Leadership
• design_services

  UI/UX & Product Improvement

  Improve usability, workflows and feature design.

  Product thinking backed by the engineering reality of what it costs to build. Usually the highest-leverage work on a product that already has users.

  • Jetpack Compose
  • React

  Built:Ghost Notes,Stitch Infinite

• auto_awesome

  AI & Automation

  Practical AI capabilities and automation, where they genuinely help.

  Applying AI where it solves a real problem in the product, and automating the repetitive parts of a workflow. I led GitHub Copilot adoption across my organisation and build AI features into my own apps.

  • GitHub Copilot
  • Prompt Engineering

  Built:ZenLife AI

• inventory_2

  I ship my own products

  These are not case studies from a portfolio I bought into. The apps and web products on this site are mine — designed, built, released and maintained by me.

• hub

  Product and engineering together

  I make the technical decisions and the product decisions, so the two do not pull against each other. Fewer handoffs, fewer things lost between them.

• all_inclusive

  End-to-end ownership

  Architecture through release: backend, app, store listing, deployment. You are not left holding the parts nobody wanted to own.

• verified

  Production-minded

  My day job is enterprise systems where an outage has real consequences. I build for the day after launch, not just the demo.

• construction

  New builds and existing systems

  Starting something from nothing and working carefully inside a codebase someone else wrote are different skills. I do both.

• chat

  Direct communication

  You talk to the person writing the code. No account manager relaying requirements.
