Cloudflare, AWS, Google (GCP + Workspace), Microsoft, Cisco, ElevenLabs, GitHub, Zoho, Claude Code, agent protocols, architecture. The deepest branch of the 2nth skill tree — the layer every other domain runs on.
Fifteen sub-categories under tech/, mirroring the canonical 2nth-ai/skills tree. Each is a branch you'll be able to walk into as explainer content lands.
ADRs, C4 diagrams, trade-off matrices, anti-pattern detection. The skill every 2nth build draws on — twelve named patterns and the honest framing of when to break them.
Full platform manifest — 16 services including Workers, Pages, D1, R2, Durable Objects, Workflows, Workers AI, Vectorize, Hyperdrive, Queues, Analytics Engine.
IAM auth model, af-south-1 region, Cloudflare+AWS hybrid patterns. Compute (Lambda, ECS, API Gateway), Security, Storage, Database, Networking, and Amazon Connect for contact centres.
GCP (Cloud Run, BigQuery, Vertex AI + Gemini, Claude via Model Garden, Pub/Sub) next to Workspace (Gmail, Drive, Sheets, Calendar, Admin SDK) — bound by one OAuth + service-account identity plane. africa-south1 residency, DWD for inbox-acting agents, the workspace-bridge Worker pattern for Cloudflare-native integration.
Azure · M365 · 3 liveAzure AI, M365 Copilot, Copilot Studio, and Entra ID — the only major LLM stack with a South Africa inference region. Azure OpenAI in South Africa North, AI Gateway in front, Workers-fronted patterns, Copilot rollout under POPIA, BYO-model Copilot Studio agents.
Salesforce's integration platform. Anypoint Platform for API management and iPaaS, plus the AgentForce-era overlay — API Catalog, MuleSoft Connector for MCP, MuleSoft MCP Server, and Agent Fabric. The path for exposing existing enterprise APIs (SAP, Oracle, mainframe) as MCP servers consumable by AgentForce and any other agent.
LiveThe post-WordPress web — structured-content CMS (Sanity, Payload, Directus, Strapi) + islands framework (Astro, Next, SvelteKit) + edge hosting + MCP as the agent-integration surface. Why WordPress is being replaced (Patchstack logged 11,334 new CVEs in 2025) and the top 5 MCP-ready web surfaces in 2026.
MCP, A2A, ACP — the protocols that let agents discover each other, share context, and hand off work. Multi-agent orchestration patterns without the magical thinking.
IOS / NX-OS, ASA / Firepower, Meraki, Webex, Netmiko automation. Five sub-areas: networking, security, wireless, collaboration, automation.
TTS (flash/v3), voice cloning, STT, conversational AI agents. Streaming patterns through Cloudflare Workers for low-latency voice.
REST API via Octokit v21, Actions, Apps, webhooks. Copilot data policy handling as of April 2026. The substrate most 2nth builds deploy from.
CRM v8 (COQL, bulk operations), Books v3 (invoices, payments), OAuth multi-DC handling, and the CRM ↔ Books sync patterns that keep sales and finance aligned.
Claude Code setup, patterns, sub-agents, skills system, MCP servers. The CLI most of this knowledge tree itself was built with.
Model Context Protocol — servers, resources, tools, and the client patterns that turn a bundle of prompts into a programmable context surface.
Infrastructure as code — Terraform, Pulumi, OpenTofu. The declarative layer that makes Cloudflare + AWS hybrid infra reviewable and reversible.
JavaScript runtimes that matter in 2026 — Node.js (the safe default), Bun (the modern challenger), Deno (the security-first alternative). Decision frame for which runtime to pick, when the hybrid pattern wins, and where each one fits in a production stack.
13 apps · 1 liveMetadata-driven Python framework with a thirteen-app ecosystem — ERPNext, HRMS, CRM, Helpdesk, LMS, Builder, Drive, Books, Wiki, Raven, Insights, Print Designer, and Frappe Cloud. Doctypes are the unit of everything.
5 areas · 1 liveHost Card Emulation — build NFC tap-to-pay wallets on Android without a Secure Element. HostApduService, APDU parsing, EMV transaction flow, Keystore security, tokenization, and South African payments context including POPIA and load-shedding resilience.
1000+ boards · 1 liveUnified embedded development platform — one CLI, one config file, every board from ESP32 to STM32 to RP2040. Build, upload, test, and debug firmware for DroneScan drones and ScanMan Hive IoT edge devices.
TS frameworks · 1 liveTypeScript libraries that sit under Workers, Bun, and Deno builds — ORMs, HTTP routers, validators. First leaf is Drizzle: schema-in-TS, ~7 kB, first-class D1 and Hyperdrive support.
Six leaves are live, more landing as content ships. Cloudflare Workers, Frappe Framework, PlatformIO, Cloudflare Edge: Africa & ME, Android HCE, and Drizzle ORM — covering compute, frameworks, firmware, regional infrastructure, mobile payments, and the typed SQL layer under Workers-owned tables.
Edge compute on V8 isolates, static+dynamic hosting on the same network. Nine sections covering what it is, why it matters, how it works, the ecosystem, use cases, evolution, the decision guide, how it connects, and resources.
The metadata-driven Python full-stack underneath ERPNext, HRMS, CRM, Helpdesk, LMS, and the rest of the Frappe ecosystem. Doctypes, hooks, REST + RPC, Bench, and the patterns that make every Frappe-built app coherent.
Regional infrastructure primer. Twenty-plus African PoPs, seventeen across the Middle East — where Workers actually execute when the user is in Nairobi, Cairo, or Riyadh, and what BGP-driven routing means for latency in regions the major hyperscalers under-serve.
One CLI for every board. Build, upload, test, and debug firmware for ESP32, STM32, Arduino, and RP2040 from a single platformio.ini. The firmware pipeline underneath DroneScan's fleet and ScanMan Hive's IoT edge devices.
Host Card Emulation for NFC tap-to-pay wallets. HostApduService, APDU parsing, EMV transaction flow, Keystore security, tokenization lifecycle, and South African payments context — POPIA, load-shedding resilience, device testing.
TypeScript-first SQL toolkit for Postgres, MySQL, SQLite, and Cloudflare D1. Schema in TypeScript, queries that compile to the SQL you'd write by hand, zero runtime dependencies, ~7 kB bundle — the default ORM for Workers-owned tables in 2nth builds.
Technology touches every branch of the tree. These are the ones it pulls on most — either because tech provides the substrate (Business, Data) or because a domain has deep integration requirements back into tech (Finance, Healthcare).
