UC Berkeley CS, EECS Honors, GPA 3.984 Incoming Databricks SWE Intern, Traffic Platform Former Amazon SDE Intern, real-time IoT infrastructure C++20, Go, Rust, Python, TypeScript Distributed systems, networking, databases, compilers, low-latency infra

Incoming intern on Databricks' Traffic Platform — networking, security, and performance engineering for large-scale distributed infrastructure in Go and Rust.

Previously Amazon SDE Intern — built real-time IoT platform processing 10K+ events/min across 100+ sensors with <500ms latency on ECS Fargate.

I build systems projects around LLM agent security, low-latency C++ infrastructure, and multi-cloud developer tooling.

Selected experience and projects. Each item links to code, benchmarks, or details.

LLMFirewall

GitHub ↗

Security proxy for tool-using LLM agents that detects prompt-injection attempts before high-risk tool calls. MCP is the protocol agents use to call external tools; LLMFirewall sits between agent and tools enforcing taint-aware trust levels, capability gating, heuristic detectors, and lightweight semantic-drift scoring.

4,200+ eval cases 100%→16% ASR (vs. no-filter) sub-ms policy checks 783 tests Python · FastAPI · MCP

C++20 Matching Engine

GitHub ↗

Exchange-style matching engine with deterministic price-time priority, FIFO fairness, and reproducible benchmark harnesses. Optimized with slab allocators, cache-conscious order layout, branch reduction, and CPU pinning. Includes Binance US market data connector, TAQ replay, and crash recovery.

20M+ msgs/sec p50 = 0.04 µs p99 ≈ 1 µs C++20 · Python · Docker · Streamlit

Synthetic local benchmark — hardware spec and harness in repo README.

Edge Deployer

GitHub ↗

Desktop deployment tool that generates provider-specific serverless configs, provisions infrastructure with Pulumi, streams real-time deploy logs, and normalizes deployment workflows across Cloudflare Workers, AWS Lambda@Edge, and Vercel. Monaco editor, per-provider ENV injection, and deployment history.
