Worked extensively on the tldraw/tldraw repository, delivering over 48 features and 20 bug fixes in nine months focused on collaborative canvas tooling, AI integration, and robust front-end architecture. Developed features such as type-constrained drag-and-drop, agent-driven canvas control, and real-time collaboration, using technologies like TypeScript, React, and Node.js. Improved accessibility and reliability through theme-aware UI updates, keyboard navigation enhancements, and rigorous test automation. Refactored core modules for scalability, introduced manager-based agent frameworks, and streamlined deployment with CI/CD pipelines. Emphasized maintainable code through documentation, schema validation, and modular design, enabling faster onboarding, safer extensibility, and a more predictable user experience.
In May 2026, the tldraw effort centered on strengthening drag-and-drop reliability and container-typing rules to deliver a more predictable, user-friendly editing experience. The team implemented type-constrained dropping so shapes can only be dropped into containers that accept their type, and extended the logic to apply these rules consistently during pointer drag as well as paste/create flows. Key work included prefiltering potential parents by child types and enhancing the DragAndDropManager to filter drag callbacks, ensuring disallowed drops are gracefully rejected during the drag operation. The effort also introduced an API surface for future improvements (canRemoveChildrenOfType) and added targeted unit tests to validate behavior. Release notes were updated to reflect the behavioral changes.

March 2026 highlights MCP app: launched a new MCP Server/UI with shape management and checkpoint persistence, deployed via Cloudflare Workers with Durable Object/SQLite and R2 image uploads, enabling collaborative canvas work and robust persistence. Build and UI: refined the MCP app build pipeline by pre-generating a combined CSS file before Vite, ensuring reliable bundling and correct dist output. State and security: introduced session IDs and embedded bootstrap data for resilient state handling, while removing image upload paths to reduce surface area and risk. Stability and dev experience: aligned dependencies and improved type safety by pinning @modelcontextprotocol/sdk to 1.26.0 and removing unnecessary type casts; updated tooling for consistency. Analytics and privacy: added analytics tracking for MCP tool usage to inform usage patterns, followed by a privacy-focused cleanup that removed frontend analytics. Domain/host handling: overhauled widget host/domain logic with a development flag for local reliability and a unified host identity model across Cursor/OpenAI Claude/ChatGPT; added domain verification endpoints and related fixes. Accessibility and UX: introduced a keyboard focus trap example and modifier-key indicators to enhance keyboard accessibility, and refined drawing/zoom loop behavior for a smoother UX. Notable fixes: Claude domain truncation for proper hosting, and well-known token endpoint updates for OpenAI verification.

February 2026: Delivered foundational improvements for scalable feature work, UX reliability, and visual consistency on tldraw/tldraw. Focus areas include a manager-based agent framework with mode controls, UX safeguards for selection-dependent actions, and UI polish, complemented by reliability fixes across theme loading, file navigation, and shape resizing. These changes reduce risk for future extensibility and improve the developer and user experience.

January 2026 (tldraw/tldraw): Delivered a key accessibility improvement by enhancing the cookie consent banner’s color contrast in dark mode. The fix uses theme-aware CSS variables to ensure legible text across light and dark themes, addressing unreadable contrast in the original UI. The work spans related components (dotcom and analytics) with synchronized color token updates and a UI tweak to align border radii with the design system. Also updated docs-related UI simplifications for PrivacySettingsLink to rely on default styling. The change is backed by the commit 1e3b436e33e4726bdc94d808f12fc09d8e86f125 and was validated through manual checks across theme modes and accessibility scenarios.
