About

I build the unglamorous systems that keep working after launch.

Most of my eight years have gone into software that outlives its first release — enterprise sales dashboards, internal admin tooling, insurance claims platforms, customer-facing finance applications. The kind of work where the second year matters more than the first demo.

I'm comfortable at both ends: designing API contracts and deployment pipelines on one side, and accessible, cross-browser interfaces on the other. I've led Agile delivery, mentored junior developers, and taken vague requirements from stakeholders through to production support.

Currently in Frankfurt, working in Angular, React, TypeScript and Node.js, and adding AWS and Python depth.

Selected work

Two builds I owned end to end.

Infosys — client: Apple 2023 — 2024

Browser-based Canvas UI Editor

A production design surface, built from scratch, letting internal teams compose and style layouts directly in the browser instead of round-tripping through a design tool.

  • Built 10+ drag-and-drop components — text, images, QR codes and element-level styling — on Angular 18 and HTML5 Canvas, cutting content-management steps for admin users.
  • Translated complex, continuously changing client requirements into a multilingual, accessible editor without re-architecting between releases.
  • Set up automated testing and CI/CD across staging and production using Spinnaker and Radar, supporting reliable delivery through the full product lifecycle.
  • Angular 18
  • TypeScript
  • HTML5 Canvas
  • Spinnaker
  • Radar

Client work under NDA — no public link or screenshots. Happy to walk through the architecture and my decisions in conversation.

IBM — ISD & GBS 2018 — 2023

Global Sales & Pipeline Dashboards

Enterprise sales intelligence for global executive stakeholders — architected from the ground up and owned for five years across two internal platforms.

  • Architected the frontend from scratch in Angular with IBM's Carbon Design System, consuming REST services across both the ISD and GBS sales platforms.
  • Engineered custom D3.js visualisations — charts and analytics tools that let executives analyse global sales targets rather than read static reports.
  • Streamlined API integration and testing with Postman to keep frontend–backend communication performant as the data volume grew.
  • Led Agile/Scrum delivery and mentored junior developers, running sprint planning and code reviews to keep delivery timelines predictable.
  • Angular
  • Carbon Design System
  • D3.js
  • REST
  • Postman

Internal IBM platforms — not publicly accessible. Architecture and trade-offs available to discuss.
