Writing
Practical lessons, architectural decisions, and engineering notes from building distributed systems and software that has to hold up in production.
Featured series
A practical series on designing external operations to remain explicit, observable, and recoverable when dependencies fail, responses arrive late, or the outcome is uncertain.
A production-focused Python retry decorator with typed sync and async support, exponential backoff, jitter, deadlines, cancellation, hooks, structured results and deterministic tests.
A practical guide to Python Requests retry policies covering urllib3 Retry, safe methods, status retries, backoff, Retry-After, timeouts, idempotency and final outcomes.
RelPrim 1.0.0 is the first stable release: a frozen public API, precise typing, hardened cancellation, timeout and fallback semantics, a stable event contract and new documentation.
RelPrim 0.11.0 adds optional JSON Schema and Pydantic v2 adapters to its existing validation, retry and fallback pipeline.
