What Has Been Built

Each project runs here as a feature. The case studies carry the architecture, the decisions and what went wrong.

01 / HashVault

June 2026 — ongoing

hashvault · api/v1control plane

# 1 · client hashes the file, asks to upload
POST /files/init-upload
{ "name": "thesis.pdf", "size": 2481152,
  "checksum": "9f2c…e41a" }

200 { "deduplicated": true }
# same bytes already stored → no presigned URL, no upload

POST /files/confirm
201 { "object": "objects/9f2c…e41a", "ref_count": 3 }
Fig. 1 — The upload path as the API sees it. A deduplication hit skips the upload entirely. Illustrative request.

Currently Building · Go

Content-addressable cloud storage.

A Dropbox-like storage platform in Go that stores identical bytes exactly once. Files are addressed by their SHA-256 hash, uploads go browser-to-S3 on presigned URLs, and the Go server never touches the data plane.

GO · GIN · POSTGRESQL · REDIS · RABBITMQ · S3 · DOCKER · TERRAFORM

Status Phase 4b shipped: deduplication. Next: integration test suite.
