A real-time collaborative markdown editor with advanced synchronization and scalable AWS deployment.

- Developed a real-time collaborative markdown editor, integrating Liveblocks for real-time editing and Yjs for CRDT-based conflict-free data synchronization.
- Utilized Prisma ORM with PostgreSQL & Redis as a cache and datastore, holding frequently accessed data in memory and asynchronously syncing to the database, reducing load times by over 90%.
- Designed a type-safe API layer using tRPC and Zod, ensuring data integrity and reducing runtime errors by 80%.
- Resolved a complex infinite save loop race condition by restructuring component state ownership and isolating CRDT state updates within the editor, with dedicated backend mutations for persistence.
- Deployed a containerized microservice architecture on AWS using Docker, ECS Fargate for orchestration, RDS PostgreSQL for persistent storage, and ElastiCache Redis for caching.

A goal setting and task planning application with AI-powered features, built for web and desktop with Tauri and React.

- Created a goal setting & task planning application with AI features, built with Tauri 2.0 for desktop and React 19 for web, serving ~180 active users from a single codebase.
- Integrated Google Gemini AI for intelligent task scheduling, automatic time estimation, and smart task creation from natural language, leveraging user context for personalized planning.
- Established bidirectional Google Calendar integration for task syncing and AI-aware scheduling that considers existing events.
- Automated CI/CD pipeline with GitHub Actions for desktop releases, Vercel deployments, and CodeQL security scanning.
- Optimized database performance using indexes and efficient SQL queries, reducing query execution time by 40-70%.
- Enhanced React component performance through optimistic UI updates and memoization, reducing page re-renders by 99%.

A full-stack social media application for community building, featuring groups, activity feeds, and scalable image delivery.

- Engineered a full-stack social media application with group photo sharing, personalized activity feeds, privacy controls, and granular security permissions.
- Led a team of 2 developers in an Agile environment, using Git for version control and Jira for task management.
- Collaborated with a design team to translate Figma prototypes into a production-ready full stack application.
- Improved PostgreSQL performance by implementing efficient data fetching with Prisma, minimizing N+1 queries and optimizing query construction.
- Integrated Cloudinary for image storage and built scalable image delivery with file transformations and CDNs, reducing bandwidth by 60% and image load times by 50%.
