Use Azure Service Bus SDK for Python to send, receive, and settle messages across queues, topics, and subscriptions with authentication and async examples.

Rust client library for Azure Service Bus. Send and receive messages through queues, topics, and subscriptions with Entra ID auth, message settlement, and RBAC roles. Note: not production ready.

Enterprise-grade messaging solution using Azure Service Bus SDK for TypeScript. Supports queues, topics, subscriptions, sessions, and dead-letter handling. Enables reliable asynchronous communication in Node.js applications with authentication and scheduling features.

This skill provides comprehensive automation for managing complex subscription billing lifecycles. It handles recurring billing, generating detailed invoices, managing failed payment recovery (dunning), calculating prorated adjustments, and ensuring accurate tax compliance (VAT, GST). Use it for implementing full SaaS subscription billing systems and automating core financial billing processes.

This skill enables expert-level development using Convex, an open-source reactive backend platform. It covers schema design, TypeScript functions, real-time subscriptions, authentication, file storage, and deployment workflows. Ideal for building new projects or integrating Convex into existing React, Next.js, or Vue applications. Supports queries, mutations, and actions with strict security constraints.

Assess on-premises Microsoft SharePoint Server farms (2013/2016/2019/Subscription Edition) during authorized red-team or bug-bounty work: fingerprint versions via response headers, map exposed endpoints such as ToolPane.aspx and Authentication.asmx, and prioritize permanently unpatched legacy CVEs.

This skill provides comprehensive strategies and technical blueprints for monetizing digital products, especially SaaS platforms. It covers everything from defining advanced pricing models (freemium, value-based pricing) and optimizing revenue flows (LTV/CAC, churn prevention) to practical Stripe integrations. Use it when you need to set up subscription plans, process webhooks, or implement automated billing cycles for your software.

Guides secure Stripe, PayPal, and Square integration: checkout flows, subscription billing, webhook handling with signature verification and idempotency, retry logic, error handling, and PCI compliance best practices.

This skill covers comprehensive PayPal payment integration, including Express Checkout, Instant Payment Notification (IPN) handling, recurring billing setups, and refund workflows. It guides developers on implementing both client-side JavaScript SDKs and server-side REST APIs for secure transaction processing. Learn to manage subscriptions, payouts, and webhook verifications effectively.

This comprehensive toolkit automates all major Stripe payment operations, including customer management, creating charges, handling subscriptions, generating invoices, and processing refunds.
