About

How I approach the work

I work where UX, process logic and engineering meet. Each project below started as a real workflow problem — manual administration, fragmented tools, an outdated system — and ended as software that the people inside the organisation actually use.

My focus is delivery: scoping the right first version, choosing technology that fits the operational context, and shipping something that holds up in production. Frameworks and AI are tools in service of that, not the headline.

Technologies and delivery areas

Beyond frameworks and libraries, this also includes delivery areas such as cross-platform applications, client portals, workflow tooling and API integrations.
