A real-time 3D graphing calculator built in Unity that compiles equations you type into surfaces you can walk around and inspect.

• Built a real-time 3D graphing calculator that compiles user-typed equations into executable functions, supporting variables, nested functions, operator precedence, and implicit multiplication.
• Rendered continuous, height-mapped surfaces by developing procedural mesh generation that samples equations across a configurable grid of 3,700+ vertices, triangulated using Unity's core Mesh API.
• Enabled real-time surface analysis by engineering a click-to-inspect feature: raycasting detects the selected point, and C# numerical differentiation computes and renders a matching 3D tangent plane.

The internal platform Safe Cities staff use to run their programs, built with a team of four and now used by 50+ people.

• Built features in Next.js, TypeScript, PostgreSQL, Supabase, and Drizzle ORM.
• Integrated Clerk authentication with role-based access and webhook syncing between the auth provider and the app database.
• Wired up Google OAuth 2.0 and the Calendar API, and added a calendar_events table through Drizzle ORM with relational links to the existing pages and programmes tables.
• Revived a paused Supabase instance, migrated the data, and added a GitHub Actions keep-alive cron so it never goes dormant again.

A six-agent workflow built with IBM's watsonx AI Agent Builder to support business decision-making and governance at scale.

• Surfaced inconsistencies and policy concerns hidden across 60+ synthetic data points by building specialized extraction agents that parsed a structured JSON dataset.
• Preserved human authority over final outcomes by architecting an auditable review process, improving decision consistency and transparency without removing the human from the loop.
