Overview
AWS re:Invent 2025 – Reinventing software development with AI agents (INV205)
In this session, Deepak Singh introduces Kiro, AWS’s AI‑powered development tool that reshapes software development through spec‑driven workflows and autonomous agents. The demo shows developers achieving 5–10× productivity gains by fundamentally changing their workflow rather than merely using AI as a helper.
Key features highlighted
- Kiro CLI – terminal‑based development environment.
- Property‑based testing – automatically generates hundreds of test cases.
- Kiro Powers – integrations with Datadog, Figma, Stripe, and other services.
A case study demonstrates an AWS Bedrock team of six developers completing an 18‑month project in 76 days using Kiro CLI. Brittany Doncaster from Delta Airlines shares how extending Kiro beyond developers to product owners and analysts drove 120 % adoption.
New frontier agents announced
- Kiro autonomous agent – continuous development.
- Security agent – proactive security analysis.
- DevOps agent – end‑to‑end operations automation.
All agents can operate independently for hours without human intervention.
Developer Testimonials: How Kiro Transformed Their Coding Experience
“Before I used Kiro, I was stuck in the details of syntax and switching between programming languages for different repositories. I would struggle with basic things like declaring a variable, but Kiro can do it for me. We now have a way to understand, interact with, and define our code, our business, and our requirements in ways we never did before. Gone are the days of spending hours debugging over a hidden semicolon. Kiro helps me through the entire process.”
“I started coding in my early teens, and the first time I wrote a piece of code and successfully ran it gave me a lot of joy. Kiro brings back that spark. Building code from scratch would have taken weeks; with Kiro we went from zero to hero in three days. It’s a partner throughout the entire process—I ask it questions, start development with it, create specs, and learn while using Kiro.”
“I’ve been adding new features to a large system. Kiro assists from ideation through requirements, tasks, and execution. My ideas become reality without the mundane keystrokes. It gives me a different perspective and enables me to do whatever comes to mind. I’m Kiro’s biggest fan.”
The AI Revolution in Software Development: From Autocompletion to Collaborative Agents
Deepak Singh, Vice President of Developer Agents and Experiences at AWS, opened the session:
“Over the last few years we’ve witnessed a major transformation in how software is built. We’ve moved from simple autocompletion to sophisticated AI agents that can write complete, multi‑file applications in one go. They can reason, help you plan, and implement software from natural‑language prompts or a diagram.”
Key points
- Refactoring that once took days now finishes in hours.
- Debugging sessions shrink to minutes.
- Projects that previously required months can be delivered in weeks; features that took weeks can be built over a single weekend.
“Agents act as collaborative assistants, providing a second brain that learns from every line of code, every commit, and every deployment. They accelerate innovation and give developers a new flow state.”
A Personal Journey: From EC2’s Launch to Today’s Developer Empowerment
Reflecting on the early days of AWS:
“In August 2006 EC2 launched in beta. I wasn’t at Amazon then; I was a bioinformatician with an S3 account. I launched my first EC2 instance shortly after S3 became available.”
“A few days later, on a whim, I fired up the maximum twenty EC2 instances allowed at the time and ran a protein secondary‑structure algorithm—a simple single‑layer feed‑forward neural network—to predict protein structures. That experiment sparked my long‑term fascination with cloud‑based compute power, which today’s AI‑driven developer tools like Kiro build upon.”
