Owned end-to-end architecture and feature roadmap for a production Point-of-Sale application using Next.js and Payload CMS. Built a RAG Discord bot for POS documentation and troubleshooting, including chunking docs and live data, generating embeddings, and storing them in a Supabase pgvector-backed vector database for semantic search. Implemented logging and analytics with PostHog, engineered reliable Payload CMS hooks to distinguish admin UI actions from programmatic API changes, and set up GitHub Actions CI/CD for automated testing and deployment. Partnered directly with the client to map operations, identify automation opportunities, and translate them into product and technical decisions.

Led and developed full-stack applications using Next.js, deployed across UAT and production environments in multiple countries. Pioneered company-wide adoption of AI-assisted development practices using Cursor, Claude, and MCP integrations to streamline feature development, debugging, testing, documentation, and code review. Designed developer workflows with MCP servers to securely let AI tools access project resources and internal tooling; created reusable prompts and workflows to standardize engineering practices. Integrated Supabase for authentication, real-time operations, and secure storage with row-level security; built custom APIs; used Redux and TanStack Query; applied SSG/SSR/ISR/CSR for performance and SEO; and delivered webhook integrations with Slack/Microsoft Teams. Wrote unit and integration tests with Jest and React Testing Library, supported CI/CD with GitHub Actions, and presented sprint demos to stakeholders.

Built and maintained public-facing web applications using React and Next.js with Material UI. Developed a car rental platform covering vehicle listings and booking flows, and a real estate platform for buyers, sellers, and brokers to manage listings across Australia. Also developed cross-platform mobile applications using React Native and Expo.
