What You Walk Away With
The program moves from fundamentals to live systems — every module is built around tools and techniques professionals can apply immediately in their industries.
Agentic AI System Design
Build, structure, and deploy intelligent multi-agent systems using LangGraph and LangChain for real workflows
Rapid Prototyping with SmolAgents
Quickly test and validate AI-driven ideas before committing to a full build — saving time and reducing risk
Compliance-Ready AI Design
Design AI systems with privacy, traceability, and regulatory compliance built in from the start — not added later
Darin Williams, a healthcare professional, enrolled in the Certificate Program in Agentic AI by Johns Hopkins University with Great Learning after a hands-on experience with Agentic AI sparked his interest in building intelligent systems. Through the program, he gained practical knowledge of LangGraph, LangChain, and SmolAgents — tools he is now using to build a multi-agent system for healthcare workflows. The program strengthened his understanding of designing AI with privacy, compliance, and traceability as first principles, helping him move from curiosity to actively developing real-world solutions in a highly regulated industry.
A Healthcare Professional Who Wanted More Than Theory
Enrolled in the Certificate Program in Agentic AI by Johns Hopkins University with Great Learning after a live classroom experience showed him what was possible. His goal was not just to understand Agentic AI but to build systems with it — specifically within the high-stakes, compliance-driven environment of healthcare.
The Moment That Started Everything
Darin can tell you the exact moment it clicked. He was in the middle of an MIT course on Large Language Models when his professor broke the class into groups and set them loose on an Agentic AI assignment. Three days later, his team had built a WhatsApp-integrated agent capable of making hotel reservations for a major hotel chain — from scratch.
Watching that system come to life was a turning point for me. I realised right then that I wanted to fully immerse myself in Agentic AI and learn everything I could — not rely on secondhand opinions or noise from others.
He started looking at programs shortly after. Most didn’t make the cut. The Certificate Program in Agentic AI by Johns Hopkins University with Great Learning is where he landed.
Depth, Structure, and Faculty Who Work in the Field
Darin went through his options carefully, weighing each against what he actually needed. Most programs didn’t make the cut.
The curriculum is, in my opinion, one of the strongest out there for Agentic AI. I reviewed several other programs, and none offered the same depth, structure, or real-world relevance.
The deciding factor was the faculty — professors who had spent time in the field, not just in lecture halls. Darin works in healthcare, where abstract knowledge isn’t enough. He needed tools he could put to work on a real problem the following Monday.
From Theory to a Live Multi-Agent System in Healthcare
Healthcare is an unforgiving environment. Decisions carry weight. Systems have to hold up under scrutiny. Darin wasn’t treating the program as an academic exercise — he was building toward something real.
The program moved through its core tools with enough depth that by the time Darin returned to his desk, he knew exactly what he was working with. He is currently building a multi-agent system in healthcare using LangGraph, with Claude and Cursor in the mix.
LangGraph
Powers his multi-agent healthcare system — maintaining traceability, human-in-the-loop control, and full auditability
SmolAgents
His proving ground for rapid idea validation before committing to a full build or development plan
LangChain
Foundational framework for connecting models, tools, and data sources into coherent agent workflows
I’ve been able to use SmolAgents to rapidly test ideas before creating a full plan for how a specific process could benefit from Agentic AI.
The program has really expanded my creativity and completely changed the way I think about software development, especially when it comes to workflow design.
Building AI That Healthcare Can Actually Trust
Most AI courses treat governance as a footnote. This program wove it through from the start — which, for someone building in a regulated environment, made a concrete difference.
In healthcare, safeguarding personal health information is absolutely critical, and the course reinforced how essential it is to design with privacy and compliance in mind from the very beginning.
The System That Kept Him a Week Ahead
Friday nights. Weekends. That’s what it cost, at least at the beginning. But once the initial friction passed, the habit took over.
Darin mapped the entire course before he started, then built a weekly plan around how much ground he needed to cover. Eighteen videos in a module meant six a day, three days running, with the quiz done before the next live session.
That simple structure kept me organised and consistently a week ahead, which made the whole experience feel manageable and even enjoyable.
How often do you get to have a mentor that works at Apple and is doing work in Agentic AI?
One Piece of Advice — and He Keeps It Simple
Darin doesn’t overthink the advice he’d give to someone sitting on the fence.
I’m going to borrow the famous Nike phrase: Just do it. Just having the knowledge prepares you for the next phase of AI, which is evolving incredibly fast — and Agentic AI is a major part of that future.
No caveats about needing a technical background. Whether you are writing the code yourself or leading a team that will, understanding Agentic AI has value at every level of an organisation.
