Staying on top of code reviews and CI/CD updates shouldn't feel like a full-time job in itself.

Check out this recording from @tsmith and Anshu Chadha from Uber's Developer Platform team on how we're tackling toil with Uber's Agentic Shift:

[Praveen Neppalli @praveenTweets]

Agentic software engineering adoption is on fire at @Uber. 1,800 code changes per week are now written entirely by Uber's internal background coding agent, and 95% of our engineers now use AI every month across all the tools we track.

This is a real reset moment for engineering; it's one of the most exciting times to lead. This shift requires builders to be curious and hands-on. I’m incredibly lucky to be surrounded by a team that’s doing exactly that.

The best part is that the strongest adoption isn’t being pushed top down from leadership announcements; it’s coming from engineers who are quietly experimenting, quietly shipping, and quietly pushing things forward.

I love spending time with those engineers because there’s no substitute for being close to the work.

Over the last few months, we leaned in hard, and the results have been phenomenal.

The bigger shift: going agentic.

84% of AI users are now working with agent-style workflows, not just tab completion. Claude Code usage nearly doubled in 2 months (32% → 63%), while IDE-based tools have largely plateaued.

Engineers are moving from accepting suggestions to delegating tasks. Even within traditional IDEs, ~70% of committed code is now AI-generated.

Background agents are writing code autonomously.

Our internal background coding agent went from <1% of all code changes to 8% in just a few months. There is zero human authoring. Engineers review and approve, but the code is written entirely by AI agents.

The role of the engineer is shifting - from writing every line to architecting systems and reviewing AI-generated code.

More to come from the @UberEng team in the coming days.

[Kotlin by JetBrains @kotlin]

At @Uber, AI isn’t replacing developers – it’s helping them move faster.
In this KotlinConf talk, @tsmith shows how Uber uses LLMs, RAG, and the Model Context Protocol to automate Java→Kotlin migrations safely across millions of lines of code.

[Ty Smith @tsmith]

The video for using Agents, LLMs, and LSC techniques to migrate Java to Kotlin for our @UberEng's Android apps from @kotlinconf is now public.

Technical excellence meets real-world leadership at #dcnyc25 🚨

The techlead summit is your toolkit for the next step in your #MobileDev career. @tsmith goes over #AI code assistants to agentic systems & explores how top teams are using AI to boost #dev productivity across the SDLC. https://t.co/q91hsASq3Q

[DevProdEng Showdown! @DpeShowdown]

Our first in-person #DPE meetup of 2025 is @PinterestEng offices in SF on Thurs Jan 23 from 3-6 PM. we have talks from @rpalcolea @AubreyChipman @NetflixEng on Testing, Pinterest on Prompt Engineering, and @Gradle on Failure analytics RSVP:

I’m building out @UberEng's first dedicated @Kotlin Language platform team in our Amsterdam office to make Kotlin first class across Bazel, IDE, LSPs, Android, KMP, AI language migrations, backend services, &amp; to help in the Kotlin Foundation.

@SarahDADAX1 Still emerging, but many long time tech folks are active. When I worked at Twitter, we categorized users in buckets, one of the smallest (sub 5% iirc) drove 80% of content and engagement on the platform. Those type of folks seem to be moving. Early, but good long term sign.

[Ty Smith @tsmith]

Seeing a lot more posts and engagement over there these days, and posting more myself. Feels a bit more like Twitter from a few years ago before my following communities fragmented across 4 platforms and many folks stopped posting on social media entirely.

Since many folks seem to be joining Bluesky, I'm https://t.co/rD91ieCBMP over there.

@adamnash @axios More likely unrealistic expectations in the newest generation due to social media influence before they reset those expectations with personal experience. Probably a hard mental shift to go through.

@joenrv @0xEricBrown Even though there's official third party passkey integration in the Android system APIs, I've found it rarely works. On my iOS device, using 1password for passkeys in most apps was a seamless experience.

[Ty Smith @tsmith]

Excited to finally be building the Kotlin Language Platform team out at Uber. Come work with us in our Amsterdam office!

[Yahya Bayramoglu @yahyabayramoglu]

We are creating a Kotlin team in Amsterdam office @UberEng ! 🥳

Let's work together! You can check out the roles and apply here.

@Stammy Moved from Spotify to Tidal years ago when they kept dragging their feet about hi-fi when they figured out they couldn't charge the customer more for it. Tidal has been great since.
