Dexla
An AI-powered app builder: drag, drop and describe your way to a real product, with the editor doing the heavy lifting.
Dexla let technical and non-technical founders ship real apps fast: a drag-and-drop editor with AI woven through it, from generating layouts to fixing bugs. I worked across the frontend, turning complex design hand-offs into a fluid, performant builder.
The signature challenge: a custom drag-and-drop engine that stayed smooth and in-sync with 500+ concurrent users editing live, pixel-perfect to the design and genuinely pleasant to use.

The hard parts.
Authored a bespoke drag-and-drop library for the editor that held up under 500+ concurrent users with real-time state synchronisation, the core of the product.
Integrated Claude & OpenAI for context-aware actions (change design, fix bugs, connect data) driving a 35% lift in engagement after release.
Translated complex Figma hand-offs into a fluid Mantine UI, the detail that earned repeated praise from designers and PMs for fidelity and polish.
Cut initial load 3.2s → 2.4s (25%) with code-splitting and render optimisation, while sustaining 98% on-time sprint delivery and mentoring through code review.
