Deep dives into distributed systems, database internals, LLMs, and things I build. I write when I feel like I've understood something well enough to explain it.
A practical deep dive into how HNSW powers vector retrieval for RAG systems, why it dominates ANN search, and how poor recall can silently degrade LLM answers.
A deep, implementation-level breakdown of how I built SRE Agent Swarm: six cooperating agents, incident FSM orchestration, safety gates, runbook execution, human approvals, and chaos-driven MTTD/MTTR scoring.
How I built a real-time collaborative document editor using Conflict-free Replicated Data Types — implementing the RGA algorithm, tombstone deletion, and out-of-order operation handling with zero external CRDT libraries.
A deep dive into building a 32-bit x86 operating system from scratch. Features a custom bootloader sequence, memory management, interactive shell, and more.
A Java-based simulation of a Linux file system, implementing core concepts like inodes, directories, and bitmap-based block allocation to understand how data is organized on disk.
How I built a SQL-compliant transactional database engine in Go with LSM Tree storage, Write-Ahead Logging, and MVCC — achieving 3× faster writes than B-Tree implementations.
Raft is beautiful once you visualize it. I built Rafty — a real-time 5-node Raft cluster simulator with deterministic fault injection — to deeply understand leader election, log replication, and network partitions.
