• Developed a VSCode extension to streamline ML workflows and MLOps, utilizing a custom Python-based LSP server to bridge the ZenML Python library with the extension's TypeScript codebase.
• Implemented real-time monitoring with the watchdog library to reflect ZenML environment changes in the VSCode extension, using an EventBus for immediate UI updates upon configuration modifications.
• Achieved direct integration with the ZenML library, removing the dependency on ZenML's FastAPI server for enhanced version management flexibility and leveraging the user's local installation for operations.
• Implemented a testing framework for AWS deployments, leveraging LocalStack, Terraform, Docker, and GitHub Actions for CI/CD, complete with detailed developer documentation.

• Developed "Pennant", a collaborative computational notebook, integrating a conflict-free replicated data type (CRDT) framework for real-time document synchronization with minimal latency.
• Led UI/UX design using TypeScript, React +hooks, React-Query, and Recoil for advanced state management.
• Built a Flask-based async execution engine with Celery, Redis, and RabbitMQ for optimal request handling and fast frontend response times.
• Implemented a robust security strategy for executing untrusted user code, combining language sandboxing, Docker hardening, and least privilege principles, with gVisor sandboxing for containerized environments.
• Optimized WebSocket communication by reducing client connections from linear to constant scale, improving overall system scalability and reducing server resource consumption by nearly 90%.
• Designed a custom nested CRDT data structure, achieving a 60% reduction in object size that allowed for more efficient state synchronization.
