Notes on reliability
Experience building stateless services, payment workflows, distributed coordination systems, and event-driven Linux networking. Interested in systems across application, networking, operating system, and infrastructure layers.
Selected systems
Stateless backend behind Nginx and Cloudflare. Dual payment gateways with idempotency, webhook reconciliation, and PostgreSQL row-level locking instead of an external lock service.
Multi-node DNS with etcd quorum, a Go REST API for records, Vault PKI mTLS, and one-hour certificate rotation with zero-downtime renewal.
RESP2 parser and non-blocking TCP server. Incremental parsing over byte streams and epoll-based readiness so the event loop never blocks.
