TheSidneySpace
I co-founded TheSidneySpace and lead its software engineering. It is an independent creative and technology company, and my work there is building the platforms and products that carry its ideas, with the same care for craft I bring to everything I make.

This site, built by hand
Designed and built from scratch: an editorial layout, a canvas dot field that follows the cursor, a small writing studio behind it, all served from the edge.

02Experience
Where I've done the work.
From teaching maths to leading mobile engineering. The full history, with roles and skills, lives on the about page.
03Capabilities
What I bring to a team.
Strong opinions, loosely held. I ask the uncomfortable questions early, then ship small and improve honestly.
Mobile
Flutter and native Swift apps that feel fast and considered, from first screen to release pipelines.
Product web
Sites and web apps that load quickly, read clearly and hold up under real traffic and real edits.
Systems
The quiet parts underneath: data models, APIs, automation and edge deployments that keep running.
Craft
Interaction detail, motion and performance budgets, because good software should feel calm to use.
