Architected a real-time multi-user collaboration engine using Liveblocks and WebSockets for concurrent editing, live cursor presence, and conflict-free shared state synchronization. Built a high-performance Fabric.js canvas rendering pipeline and reduced perceived latency by 35% using optimistic UI with delta-based state diffing while sustaining 60fps on desktop and mobile.

Converted click-only div/span UI to semantic elements with ARIA roles, keyboard handlers, and focus styles, resolving WCAG 2.1 Level AA keyboard navigation violations. Improved form UX by removing blocking alert() validation popups, refactored 5 UI timeout magic numbers into a typed constants module, and enhanced accessibility via prefers-reduced-motion across 6 animation classes.

Integrated Radix UI ScrollArea primitives into the reaction drawer with vertical scroll for reactants/products and horizontal scroll for species/parameter autofill, eliminating UI overflow across reaction configurations. Prioritized reaction-specific species in autofill lists to reduce input friction for complex multi-reactant reactions.

Designed and implemented a CategorySchema Zod validator with unit tests and documented usage examples following established schema patterns, merged into main as an SSoC ’26 medium-level contribution.

Fixed a curriculum inconsistency in a Relational Databases Bash Scripting quiz by correcting stylistic parity across 4 answer options, merging to main and impacting 500k+ learners.

Diagnosed and fixed a post-auth navigation bug where dashboard redirect paths were incorrect in login/register flows, identifying the root cause via route config analysis and delivering a surgical one-line fix.
