API Integrations Masterclass
How production messaging APIs are actually shaped — resources, idempotency, throughput and versioning — and how to integrate with them without waking up at 3am.
Webhook Engineering
Producing and consuming webhooks you can trust: signatures, replay protection, retries, dead-letter queues and production debugging.
Chatbot Conversation Architecture
Design conversations as explicit state machines: slots, context, menus, human handoff and how to measure whether any of it works.
IP Messaging Protocols
What changes when messages ride on IP instead of signalling channels: transports, channels and threads, receipts, ordering and bridging back to SMS.
SDK Design
Design client libraries developers enjoy: resource-shaped APIs, errors as values, sane retries and documentation that ships with the code.
Build a Tiny CPaaS
Assemble a minimal communications platform from first principles: routing, carrier abstraction, metering, observability and tenant isolation.
