Profiled an LSM tree engine in Go from 250k to 2M writes/sec, making it 5x faster than BoltDB. Deep dive into write-ahead logs, memtables, and why B-Trees win on read paths.

Bypassing fsync bottlenecks by implementing io_uring in pure Go using raw syscalls — no CGo, no libraries. Achieved 5.5x throughput over naive fsync at 64 concurrent writers.

Peeling back the abstraction to understand what containers really are at the kernel level — namespaces, cgroups, and the illusion of isolation.

Designing a high-performance distributed pub-sub broker in Go from scratch, achieving 62x throughput over Redis using lock-free ring buffers and zero-allocation message paths.

A complete journey through Bluetooth reverse engineering — from false starts to successful ANC control without the HeyMelody app.

Solving the AI cold start problem. Achieving 0.003ms wakeup times for massive models by 'cheating' physics with pre-pinned memory pools.

Introducing Engram: A high-performance persistence engine for autonomous agents that never forget, even after a system crash.
