No Code and Low Code Agentic AI Applications

Dr. Alfred Ang is a full-stack AI developer and Agentic AI solution architect who takes visual workflow tools as seriously as code. n8n, Langflow and Flowise sit alongside the OpenAI Agents SDK, Google Gemini Agent SDK, Claude Agent SDK, Microsoft AutoGen and CrewAI in the toolkit he uses to design multi-agent systems, RAG pipelines and automations for customer service, internal workflows and decision support. He is Managing Director, CIO, CTO and Chief Instructional Designer of Tertiary Infotech Academy Pte Ltd and founder of Tertiary Courses, holds a PhD in Electrical Engineering from NUS, and is a Microsoft Certified AI Engineer Associate (AI-102) and Power App Maker (PL-100), an AWS Certified Solutions Architect and AI Practitioner, and an IBM certified instructor for the AI Practitioners course. His public n8n work is extensive: n8n-ragdemo, a no-code RAG demo in which uploaded PDFs feed a vector store and a Telegram AI agent answers questions; n8n-ragdemo2, which ingests course brochures into Supabase, Pinecone or Qdrant for a customer-service chatbot; n8n-hrportal, a self-service HR portal with human-in-the-loop leave approval and an OpenAI HR chatbot guarded by input and output guardrails; n8n-inventorycontrol, an inventory forecasting agent driven by a local LLM; and iotplatform, a low-code IoT platform automated with drag-and-drop n8n flows. He also holds an MSc in Electrical and Electronic Engineering from NTU and a Certificate in AI Ethics and Governance (Senior Professional) from NTU, and is an ACTA-certified trainer and DACE-certified curriculum developer who designs practical, workplace-focused courses.

On No Code and Low Code Agentic AI Applications, Dr. Ang supports learners as they build working agents in n8n by connecting nodes on a canvas instead of writing full programs. The course starts with no-code agentic AI workflows: triggers, AI agent nodes, chat models, memory and tools that let an agent reason and act. It then moves into low-code workflows, where small expressions, code nodes and API calls extend what an agent can do, before closing with real-life applications such as document question answering, customer enquiries, approvals and reporting. Having built these patterns himself, he helps learners avoid the common traps, such as missing credentials, unclear agent instructions, unchecked outputs and workflows that fail silently, and he shows where a human approval step belongs. His Power Platform certification also lets him compare n8n with other low-code options learners may already use at work. He keeps the pace practical for business users, analysts, operations staff and IT professionals alike, giving individual help as learners debug their own flows. Each learner leaves with workflows they built and understand, and a clear path to automating tasks in their own role. He also stresses good habits such as naming nodes clearly, testing with sample data and documenting each workflow, so that colleagues can maintain what learners build after the course.

As an AI enthusiast with a data-driven, cost-conscious approach to marketing, he is well suited to helping business users and operations staff see where agentic AI can save time and where human judgement still matters.

No Code and Low Code Agentic AI Applications teaches participants to assemble AI agents in n8n by connecting nodes on a visual canvas instead of writing traditional code. Learners first develop no-code agentic AI workflows, then extend them with low-code steps, and finally apply them to real-life scenarios in which agents reason, use tools and connect to business applications to complete multi-step tasks. Allen draws on his experience across several industries to help participants pick workflows worth automating and define what a good result looks like. The outcome is a set of working n8n agent workflows and the confidence to identify further automation opportunities in their own teams.
