A production-grade, self-healing SRE control plane built as a 6-agent swarm (Observer, Diagnoser, Remediator, Safety, Orchestrator, Learner) over NATS JetStream. Monitors 10+ polyglot microservices, performs LLM-assisted root cause analysis with Gemini/OpenAI fallback chain, enforces safety gates with human-in-the-loop approvals via a React dashboard, executes YAML runbook-based remediation, and scores MTTD/MTTR with chaos engineering scenarios. The Learner agent uses RAG over ChromaDB to recommend runbooks from historical incidents.

An interactive, browser-based visualizer for the Hierarchical Navigable Small World (HNSW) algorithm. Simulates multi-layer graph construction, greedy top-down nearest-neighbor search, random-level assignment, and degree-pruned edge linking, with live layer isolation, operation logs, and graph statistics to make vector search internals intuitive.

A from-scratch, educational 32-bit x86 operating system written in C and NASM assembly. Boots via GRUB, runs an interactive shell with syscalls, keyboard input, filesystem, and VGA text-mode display — all with zero external dependencies.

A 5-agent LLM-powered equity analysis system using LangGraph orchestration, integrating RAG over financial reports via Qdrant and real-time sentiment analysis. Delivers structured BUY/SELL/HOLD signals with confidence scores across RSI, MACD, and Bollinger Band indicators.

SQL-compliant database built from scratch with LSM Tree storage, Write-Ahead Logging for crash recovery, and MVCC-based ACID transactions. Achieves 3× faster writes than B-Tree implementations for write-heavy workloads with 10K+ transactions/sec.

Real-time distributed consensus visualizer simulating a 5-node Raft cluster with a virtual networking layer. Enables deterministic fault injection and demonstrates 99.9% consensus achievement under network partitions and node failures.

A real-time collaborative document editor built from scratch using CRDTs (Conflict-free Replicated Data Types). Implements the RGA algorithm with tombstone-based deletion, an insert backlog for out-of-order operations, and deterministic tie-breaking — enabling conflict-free multi-user editing over WebSockets with zero central coordination.

Production-grade file system simulator implementing ext2/ext3 architecture with inode-based storage, directory management, and bitmap allocation. Reduces storage lookup complexity from O(n) to O(1) for 1000+ files.
