About Me

I am a second-year Software Engineering undergraduate focused on AI agent systems, backend infrastructure, and DevSecOps tooling. I build and orchestrate autonomous AI agents across engineering workflows, including system architecture, implementation, automated code review, and security testing.

My core work centers on concurrent systems in Go and Python, WebAssembly runtime extensions, and privacy-first security tools.


Featured Projects

  • ShadowGuard
    Air-gapped DevSecOps VS Code extension built in Go and TypeScript. Analyzes source files in real time using concurrent Goroutines and Shannon Entropy to catch leaked secrets and API keys with zero telemetry.

  • Aegis Proxy
    Zero-downtime reverse proxy written in Go. Uses WebAssembly (WASI) sandboxing via TinyGo and RWMutex locking to hot-swap security middleware without dropping live connections.

  • GraphRAG Interceptor
    Real-time AST parsing and GraphRAG proxy engine in Python. Intercepts OpenAI-compatible completions, extracts functional references, and injects 2-hop downstream Neo4j codebase dependencies into streaming LLM context windows.

  • FaultLine
    Localized chaos engineering proxy. Intercepts raw TCP/IP streams between application layers and databases to inject jitter, latency, and sudden connection drops, testing resilience under network faults.

  • Nexus Ecosystem
    Multi-threaded chat and banking system in Java. Implements SSL/TLS encrypted TCP/IP networking, SHA-256 password hashing, and ACID-compliant JDBC transaction management.
