An in-memory key-value store in Go with a single-owner execution model, a checksummed write-ahead log, versioned snapshots, and asynchronous replication with partial resync.
Nolan Nguyen
Backend Engineer — distributed systems & infra
Currently building backend infrastructure at Axon Enterprise Vietnam. Previously Proxel, Cohost AI.
I build backend systems that stay correct under concurrency, failure, and load: an in-memory database with a checksummed write-ahead log and asynchronous replication, a proxy layer with per-upstream circuit breakers, and a workflow engine reworked from 50 nodes down to 10 while holding the same 50 concurrent jobs. Based in Ho Chi Minh City, Vietnam.
Selected Projects
An HTTP/HTTPS proxy with per-upstream circuit breakers, retry/backoff, and Redis-backed rate limiting, coordinated with a browser-automation worker over Redis Streams consumer groups.
A media transcription platform that turns hour-long audio and video into cited transcripts and summaries as background jobs, plus a v2 design for idempotent, ledger-based credit settlement.
A fine-dining ordering platform: Django REST + Channels backend, React SPA frontend, Stripe checkout, and real-time order notifications over WebSockets.
