Recommended Learning Paths
From networking fundamentals to full-stack APIs and E2E automation testing.
From unit tests to E2E load testing, then a fully automated test agent — closing the quality loop.
From Harness/MCP fundamentals to multi-agent frameworks and AI coding assistants.
From agent design patterns to TS framework practice with FirstMate fleet orchestration.
From LangGraph workflows to Deep Agents approval flows, landing on AWS ECS/SQS production deployment.
From gateway-agnostic LLM calls to production-grade agent systems, then fine-tuning and inference.
