Work

Okiynai

AI-powered e-commerce platform with autonomous agents where I mostly worked on multi-tenant architecture from auth, to domains configuration and auto ssl provisioning, and edge routing.

Postgres WAL Visualizer

Built a PostgreSQL WAL observer for inspecting database changes and WAL records. I also Built load-generation tools to simulate continuous database writes for live WAL inspection.

Kafka io_uring

Built an Apache Kafka-inspired single-broker append-only log to explore io uring. And I've also Profiled I/O behavior with strace, execution traces, and flamegraphs to identify bottlenecks.
