redis/rueidis
A fast Golang Redis client that supports Client Side Caching, Auto Pipelining, Generics OM, RedisJSON, RedisBloom, RediSearch, etc.
DiceDB/dice
DiceDB is an open-source, fast, reactive, in-memory database optimized for modern hardware.
authzed/spicedb
Open Source, Google Zanzibar-inspired database for scalably storing and querying fine-grained authorization data.
p2-inc/keycloak-orgs
A Keycloak extension enabling single-realm, multi-tenancy for SaaS applications
Projects
cadutrace
An offline CCSDS protocol analyzer for spacecraft telemetry, walking a recorded CADU stream up the stack - transfer frames → virtual channels → reassembled space packets → application decoders - into a health report or an interactive terminal UI.
Autorollout
A CRD-free Kubernetes operator that triggers rolling restarts of Deployments when the ConfigMaps or Secrets they consume actually change.
For the Curiosity
Smaller builds, weekend hacks, and rabbit holes explored along the way.
Go Software RAID
User-space RAID 0/1/5/6 in Go, file-backed disks with block I/O through a RAID abstraction layer. RAID 5 (XOR) survives 1 disk failure and RAID 6 (Galois-field dual parity) survives 2; usable capacity 100/50/75/50%. Covered by 14 unit tests.
CoWIN Slot Finder
A vaccination-slot discovery web app from India's 2021 COVID drive, a React (Vite) SPA over a stateless FastAPI proxy to the public CoWIN API, with State → District → Center navigation and pincode search. No database, no auth; migrated from an original Django build.
