Jun 1, 2026June 2026 monthly summary for manifold (manifoldmarkets/manifold). Key feature delivered: Sports Market Performance Enhancement by adding a partial expression index on contracts((data->>'sportsLeague')) to optimize queries involving the sportsLeague field. Implemented an idempotent migration (chore(db): add migration file for contracts_sports_league_idx) using IF NOT EXISTS to ensure compatibility with existing environments while supporting fresh databases. The index has been created concurrently in production; this migration formalizes the setup for CI and new deployments. This work improves read latency for sports market endpoints, live-poll gating, and resolver scans, contributing to faster, more reliable data access.

Apr 1, 2026In April 2026, delivered key UI/UX enhancements for the manifold project while maintaining build stability amid schema migrations. Key features delivered: Dynamic April Fools hat scaling based on entitlement count, enabling a gradual, engaging size progression for event participation. Major bugs fixed: temporary workaround for a missing is_bot column in Supabase schema, casting the selection to any to bypass type-checks and unblock builds, preserving referral/display features. Impact: improved user engagement during the event, no release delays, and preserved feature parity. Technologies/skills: TypeScript, Supabase, build pipeline discipline, migration handling, and debugging under pressure.

Feb 1, 2026February 2026: Delivered data integrity improvement and accessibility enhancements on manifold. Fixed a bug in cover image handling to delete the existing image when coverImageUrl is cleared, preventing stale references and ensuring data consistency. Added a touch-friendly accessibility improvement to keep the edit pencil visible on landscape mode for touch devices (e.g., iPads), replacing hover-only behavior. These changes strengthen data reliability, UX for editors on mobile, and overall editor maintainability. Tech focus included TypeScript/React patterns, CSS media queries, and careful commit hygiene.
