Deep understanding of rate limiting, adaptive throttling, queue-based request management, retry/backoff, idempotent webhook handling, background job processing, event-driven architectures, bulk & data operations (GraphQL bulk queries/mutations), high-volume import/export, data migration tooling, and custom sync engines. Scheduled background processing pipelines.
• Headless Commerce: Building storefronts using Hydrogen (React-based), modern React Router patterns, deploying to Oxygen, and designing hybrid/headless commerce strategies with secure integration to backend services.
• Infrastructure & DevOps (Azure-First): Microsoft Azure, App Services, Container Apps, Networking, Secrets management, Monitoring & logging, Docker, CI/CD pipelines (GitHub Actions / Azure DevOps), environment management & configuration strategies, zero-downtime deployments, rollback strategies, observability & performance monitoring.
• Backend Engineering: Node.js or PHP (Laravel preferred); strong TypeScript proficiency; advanced SQL; ORM usage (Prisma or equivalent); background job systems; queue management; caching strategies (Redis or equivalent).
• Testing & Quality Engineering (Non-Negotiable): Strong automation discipline: Playwright for E2E testing (mandatory), unit testing (Jest/Vitest/PHPUnit), API contract testing, webhook simulation frameworks, load testing for checkout flows, CI-integrated test pipelines, deterministic testing for subscriptions & recurring billing. Testing in the context of checkout reliability, subscription lifecycle, shipping rate correctness, and data integrity under load.
• AI & Advanced Systems: Production experience with Retrieval-Augmented Generation (RAG), agentic workflows, tool orchestration, multi-step reasoning systems, MCP-style integrations, safe AI integration into commerce flows, evaluation & observability of AI systems.
