Auralis

Serialized-Audio Streaming Platform

A platform for original serialized audio: listeners follow shows season by season and resume to the second across devices, creators publish episodes or generate whole series through an asynchronous AI pipeline that writes the script, synthesises the speech, and packages HLS audio. Eight independently deployable services, one database each, domain events delivered through a transactional outbox.

8 services, database-per-service, outbox-relayed events

Distributed SystemsGolang

NuclaDB

Vector Search Engine, Built From Scratch

A vector database written from scratch in Go: HNSW indexing, a crash-safe write-ahead log, mmap-backed snapshots, and tenant-isolated multi-tenancy with scoped API keys. Product quantization and a Raft-sharded cluster exist as tested packages. Benchmarked head-to-head against a real Qdrant instance, not wrapped around one.

Distributed SystemsGolang

VantageEdge

Multi-Tenant API Gateway

Multi-tenant API gateway in Go that routes requests to tenant-registered origins by subdomain. Clerk JWT and scoped API-key auth, Redis-shared rate limiting and response caching, health-aware load balancing, and config pushed from a separate control plane over gRPC, instrumented with Prometheus and OpenTelemetry.

Developer Tools

CLIs and utilities that each do one job. 26 in the toolbox.

FlakeGuard

Tells flaky tests from broken ones and quarantines the flaky ones so they stop blocking merges.

layerlens

Shows what each container image layer adds, and the bytes later layers hide.

Rust

depblast

Finds which of your projects ship a package version, and the dependency chain that pulls it in.

hookrelay

Self-hosted webhook relay: capture, inspect, verify and fan out webhooks with retries.

Python

stagewatch

Breaks LLM server latency into queueing, prefill and decode, under realistic load.

rowdiff

Diffs two CSV exports by key, even when the files are bigger than RAM.
