From SDLC to AI-DLC: Changing how software is built
AI agents may be making code faster to write, but they’re also shifting the bottleneck further down the delivery process. This talk explores why proven practices like progressive rollout, observability, feature flags, and automated rollback are becoming essential for teams adopting AI at scale.
-
How we migrated from manual deploys to agent-driven development in under six months
This talk will dig into the technical and social details of Imprint’s migration to safely transition from manual deploys to continuous deployment with substantial agent-written PRs in under six months.

This talk takes Steve Yegge’s “continuous thunderdome” as a starting point and shows how to make CI/CD work at planet scale, and how to solve the perennial problem that nobody wants to fix the build.
-
Startup made, enterprise grade: Earning trust, scoping tight, and shipping quality with a small team
Small teams are increasingly expected to build for enterprise-scale customers, and AI is changing how they get there. This talk explores how startups can ship enterprise-ready features with lean teams, what’s changed along the way, and how they’re adapting for what comes next.
-
Obsessing over AI is optional
This talk is for overwhelmed engineering leaders and senior ICs who feel quietly guilty about not experimenting with every AI trend.
-
The data canary: How Netflix validates catalog metadata
This talk tells the story of how we built the Data Canary: an automated system that validates data transformations using real production traffic, detects regressions in 2.5–4 minutes, and blocks bad data from publishing, all within a 10-minute window.
-
The real impact of AI on software engineering
This session presents the key findings from LeadDev’s AI Impact Report 2026 – and the numbers tell a more complicated story than the productivity anecdotes suggest.
-
One shot at scale: Surviving the Super Bowl signup surge
This talk goes behind the scenes of how Fetch prepared for a massive Super Bowl traffic spike, scaling from around 1 signup per second to a target of 150,000. It explores the engineering decisions, architectural trade-offs, stress testing, and launch-day processes that helped the team manage risk when there was only one chance to get it right.
-
The accountability gap: Engineering governance for autonomous AI
This session walks through an engineering framework for accountable autonomy: a three-tier trust model that categorizes decisions by blast radius (impact and reversibility), an autonomy budget that meters agent trust with SLOs and revokes it automatically when behavior degrades, and circuit breakers that freeze an agent before a bad pattern becomes an incident.
-
Evaluating AI developer tools without the drama
This talk explores how to turn a divided technical evaluation into a decision everyone can trust. Through a real-world AI code review tool rollout, you’ll learn a practical framework for setting shared criteria, rebuilding developer confidence, and making technical decisions with genuine stakeholder buy-in.
-
How to kill the code review
This talk explores why traditional code review is struggling to keep up with AI-driven development. It introduces a five-layer trust model designed to help engineering teams validate AI-generated code, reduce reliance on manual review, and ship faster without sacrificing quality or control.
-
Building trustworthy agents at scale
This talk explores that journey: how we built testing pipelines for non-deterministic systems, defined “ethical success criteria,” and aligned engineers, product managers, and legal teams around shared principles for responsible AI.
-
Legacy as leverage: How brownfield work builds technical judgment
In this talk, I’ll share how brownfield work builds engineering judgment in ways greenfield environments often do not.
-
You’re already building a software factory
This session will give you a blueprint for building out your team’s factory, both technically and organizationally.
-
Beyond CI/CD: How platform abstractions unlocked developer productivity at scale
In this talk, I will share how our platform engineering team made a deliberate investment to simplify service-to-service connectivity by introducing uniform platform abstractions and out-of-the-box discovery.
-
The first rung: Where the next generation of engineers will come from
A look at how apprenticeship can help engineering leaders develop the next generation of technical talent for an AI-enabled world.
-
AI-native development: How to actually get the most out of your agents
This talk covers spec-driven development as a way to give agents better constraints, large language model (LLM) gateway and routing strategies for managing which model handles which task, test-driven development adapted for an agent-first workflow, and verification practices built for the volume and pace of AI-generated code.
