From Nervous to Confident: Running My First Amazon Bedrock Workshop
A reflection on delivering my first technical workshop as a guest speaker, and how five weeks of public-speaking lessons turned pre-talk nerves into real confidence on stage.
A few weeks ago, on September 22, I stood in front of a room and ran a hands-on Amazon Bedrock workshop for the AWS Student Builder Group IUC. The invitation itself was a bit of a surprise and a real highlight: I was reached out to on LinkedIn and asked if I'd come run the workshop as a guest speaker. Saying yes was easy; it was exactly the kind of opportunity the New Voices program had been preparing me for.
It was my public-facing talk for the AWS New Voices program, and it was also the first time I'd delivered a technical workshop like this. This article is my reflection on that experience: what I built, what I learned about public speaking from the program, and how five weeks of New Voices sessions turned "I hope I don't freeze up" into "I've got this."
What is AWS New Voices?
AWS New Voices is a program designed to help people who haven't done much public speaking find their footing on stage. Over five weekly sessions, it walks you through the things that actually make a talk land: how to open strong, how to structure a story, how to design visuals that support you instead of distracting the audience, and how to handle the room. To graduate, you commit to three things: attend all five sessions, deliver a public-facing talk, and publish a reflection like this one. This is me closing that loop.
The workshop: a working Amazon Bedrock demo
I didn't want to give a slides-only talk about generative AI. I wanted the audience to see a real model respond to real questions, so I built a small end-to-end demo on Amazon Bedrock.
The architecture was deliberately simple so anyone in the room could follow it:
1
Browser (chat UI) -> Express backend (/api/chat) -> Amazon Bedrock (Converse API)The whole point of that middle layer was a security lesson: the Bedrock API key lives only on the server, and the browser never sees it. Credentials stay server-side. It's a small detail, but it's exactly the pattern you want people to walk away with.
The part that got the "wow": grounding a model in your own data
The demo everyone remembered was the Retrieval-Augmented Generation (RAG) piece. I invented a fictional company, Nimbus Coffee Co., and wrote a handbook for it: products, prices, a rewards program, a return policy called the "Bad Cup Guarantee," even a signature drink (a vanilla-lavender latte with blue spirulina "cloud" foam).
Then I ran the same question two ways:
- Without the Knowledge Base, I asked, "What is Nimbus Coffee's return policy on beans?" The model had no idea. Nimbus doesn't exist, so it either admitted that or made something up. That's hallucination, live and in front of everyone.
- With the Knowledge Base, I asked the exact same question. This time it answered correctly (30 days, even if opened) and showed a citation pointing back to the handbook.
Same model, same question, completely different outcome. That contrast was the heart of the talk: a general-purpose model becomes an assistant that knows your stuff the moment you ground it in your own documents. Swap the coffee handbook for a real company's docs and you've got a support bot.
I also kept a few honest "gotcha" questions ready, like asking for Nimbus's stock price, to show the limits: good RAG answers from what it was given and shouldn't invent what isn't there.
We wrapped up with a Q & A (and some pictures!)
What AWS New Voices taught me (and how I used it)
Here's the honest part: the technology was the easy bit. Standing up and presenting it was the thing I was nervous about. The program gave me concrete tools, and I leaned on all of them.
Build a powerful introduction. New Voices drilled into me that the first 60 seconds decide whether the room is with you. Instead of opening with a definition of generative AI, I opened with a hook and a promise about what they'd see working by the end. It bought me the room's attention early, which settled my nerves far more than any amount of rehearsing the middle section did.
Talk about the journey. Rather than a feature tour, I built the talk as a journey, and I anchored it in my own experience learning Bedrock. Sharing where I got confused and what finally clicked made the content relatable and gave the whole thing a narrative arc instead of a list of services. The audience was following a story, not a spec sheet.
Make the visuals work for you. The program changed how I thought about slides and demos. The live chat UI and the before/after RAG contrast were the visuals: simple, legible, and designed to make one point at a time. When the visual carries the idea, you're free to talk to the room instead of reading to it.
Engage, don't just present. I asked the audience questions and took theirs throughout. New Voices gave me the confidence to treat Q&A as part of the talk rather than a scary thing at the end. Because I'd prepared a list of the handbook questions and their correct answers ahead of time, nothing from the room caught me off guard, and that preparation is exactly what let me relax and actually enjoy the conversation.
What I'm taking with me
The biggest shift wasn't technical. It was realizing that confidence on stage comes from preparation and structure, not from being a naturally outgoing person. A strong open, a clear journey, visuals that do the heavy lifting, and genuine engagement with the room: those four things carried me through, and they'll carry me through the next talk too.
A special thank-you to Andy Tchouta, the leader of the AWS Student Builder Group IUC, who invited me and hosted the workshop. Thank you for the opportunity and for making me feel so welcome as a guest speaker. And to everyone in the New Voices program and everyone who gave feedback along the way: thank you. I walked in hoping to survive a talk, and I walked out wanting to do the next one.
If you're on the fence about speaking publicly, build the thing you're excited about, prepare like the room will ask you anything, and start strong. The rest follows.
Thanks for reading. If you're curious about the Bedrock demo or the Nimbus Coffee RAG setup, I'm happy to share more.
