Engineering-blog reads, distributed-systems pieces rebuilt in Go, and a homemade AI journal called Lumina.
What they're building.
Lumina
LaunchedAn ambient AI journaling app where people write entries and reflect on them in an AI chat that knows each entry's context.
Started as memo-mate, then renamed Lumina; went live on Vercel in October 2026.
Go vector search library
BuildingA lightweight vector search library for Go developers that sits beside an existing SQL database and answers plain-English queries via pgvector.
MiniNeki
BuildingA tiny version of Neki's sharding topology, built to learn the basics of how its router sends queries across shards.
Snowflake ID generator
LaunchedA from-scratch Go implementation of Twitter's Snowflake that serves timestamp-based 64-bit IDs over gRPC, stress-tested with zero collisions.
Grew out of the Unique ID Generation challenge in October 2026.
Spec-to-Protobuf pipeline
BuildingA Go prototype that turns one API spec into Proto3 contracts and REST route metadata, and flags breaking wire changes against a baseline.
