Selected work

Practical architecture.
Measurable impact.

Examples of the systems and experiences I have helped build, described at a public level.

01

Shared frontend architecture

Designed reusable UI patterns and micro frontend boundaries for enterprise applications, giving teams a common foundation while allowing independently delivered features.

ReactTypeScriptModule Federation

Architecture: Shared React dependencies, a component system, and event-based coordination across applications.

02

Performance by default

Led a UI overhaul after profiling real bottlenecks. A measured proof of concept helped make bundle size, rendering cost, and reusable components part of feature planning.

Outcome: Approximately 40% reduction in load time, with performance practices adopted across teams.

03

Enterprise search and AI experiences

Built interfaces for an AI-powered chatbot, People Finder search, document viewing, and visual exploration of connected data at AstraZeneca.

Focus: Make rich data and complex workflows usable through responsive, maintainable interfaces.

04

Enterprise mobile workflows

Delivered cross-platform React Native applications for iOS and Android with reusable components, TypeScript, Redux, and API integration.

About my approach

Build for the people who use and maintain it.

My work has spanned AstraZeneca, Adecco, and earlier enterprise teams. I like systems that make the next feature easier to build and the product easier to use.

I lead technical discussions with product, design, and backend partners, then stay close to implementation and the evidence from real usage.

01

Start with the user and the bottleneck

Understand the workflow, profile the current experience, and establish what better looks like before choosing an architecture.

02

Make the useful pattern repeatable

Give teams shared components, clear ownership, and room to build independently where the product needs it.

03

Validate after release

Use tests, performance signals, and developer feedback to improve the system as more teams adopt it.
