Predileto '#13 - Scoped Concurrency in Async Python Workers
Software DevelopmentHow we built a gather_with_concurrency utility to parallelize Google Places API calls inside an SQS worker — and why scoped semaphores are safe in single-loop async architectures.
-
Predileto '#12 - Domain Events and Command Queues in Async Python
Software DevelopmentHow we designed a unified domain events bus alongside dedicated command queues in our Python backend — the architecture, the code, every design decision, and the trade-offs of event-driven async systems.
-
Predileto '#11 - Implementing the Unit of Work Pattern in Async Python
Software DevelopmentHow we implemented the Unit of Work pattern with async SQLAlchemy to fix transaction inconsistencies across three bounded contexts — from the problem discovery to the final implementation with code walkthroughs.
-
Predileto '#10 - Async Concurrency Patterns for IO-Bound Python Services
Software DevelopmentHow we went from sequential awaits to controlled concurrency in our Python AI pipelines — covering asyncio internals, semaphore-based throttling, Celery thread pools, LangChain thread safety, and the tradeoffs that matter when your bottleneck is API latency.
