Professional Experience
Founder & AI Software Engineer
HP OS — Independent Project / Product
A local-first AI platform combining HP Control Center, backend microservices, an AI Agent Runtime, workflow automation, REST APIs, and infrastructure monitoring.
- Architected a local-first AI operating system integrating HP Control Center, backend microservices, an AI Agent Runtime, and workflow automation.
- Engineered backend architecture and RESTful APIs for asynchronous task orchestration, user authentication, and Redis/RabbitMQ queue processing.
- Implemented end-to-end task execution pipelines featuring automated planning, tool execution, multi-stage verification, and real-time health telemetry.
- Configured persistent data layers using PostgreSQL, MongoDB, and Redis caching for low-latency state synchronisation and infrastructure monitoring.
- Integrated modular local AI generative applications (HP Music Studio, HP Vision Studio, HP Video Studio) communicating over internal APIs.
- Documented comprehensive platform architecture, testing matrices, and operational recovery runbooks.
Selected Projects
PastelChat
React.js, Node.js, MongoDB, Socket.io, Electron, OAuth 2.0, JWT
Production-ready real-time communication platform supporting multi-tenant messaging across web and desktop clients.
- Built a full-stack real-time messaging platform supporting 50+ active users and 1,000+ daily messages without critical production incidents.
- Implemented OAuth 2.0 (Google & Microsoft) and JWT authentication with session handling, reducing unnecessary API roundtrips by 40%.
- Optimized MongoDB schema indexing and backend initialization, decreasing cold-start latency from approximately 30 seconds to under 2 seconds.
- Automated CI/CD deployments to Vercel and Render with continuous uptime monitoring via UptimeRobot, maintaining 99.5% availability.
ReproSpec
Node.js, JavaScript, TypeScript, Docker, SHA-256, npm
Portable evidence capture and sandboxed replay CLI toolkit for reproducible bug diagnostics.
- Engineered a Node.js CLI tool implementing an open specification for generating portable, tamper-evident software issue reports.
- Implemented configurable regex redaction and cryptographic SHA-256 integrity verification to sanitize and validate bundles prior to execution.
- Built an isolated Docker replay runner utilizing disposable execution copies and offline network constraints to safely reproduce bugs.
