Currently looking for an software/infra engineering position. I'm based in Turkey (but open to remote/relocation), and interested in Ruby, Python & Kubernetes, and general infrastructure management.

I think Yasar would be a great addition to any high powered team. I've always come away impressed with every chat and interaction I've had with him. He is a passionate and driven engineer who cares about the things he works on.

Early bird tickets for #railsconf2025 are selling like hot cakes right now. If you don't want to miss your chance, don't walk, run to the site.

I told you they would go fast. We've now sold the last 2 Early Bird tickets and they are all gone. Regular tickets are up for sale now. We are seeing increased demand for what will be the last RailsConf, so buy your tickets as soon as you can, or risk having FOMO forever.

3 key lessons from Shopify's Vinicius Stock at #tropicalonrails: 1⃣ Strong defaults impact developer experience more than configurability 2⃣ Standardized tooling enables more reliable integrations and requires less configuration from users 3⃣ We can use standardization to push

I know that a lot of people are really happy because of the LSP features in ruby_lsp, but I'd say that the awesome part is the DAP integration. That "Debug" code lens for tests saved me countless hours. Thank you Ufuk Kayserilioglu, Vinicius Stock, Stan Lo & the rest of the ruby_lsp team!

I just published "Implementing Embedded TypedData Objects" about a feature Jean Boussier and I worked on for Ruby 3.3. A bit late, but better than never. railsatscale.com/2025-06-03-imp…

The weather this time of year in Philly generally changes a lot day to day so take the forecast for RailsConf with a grain of salt. Here's my suggestions for anyone traveling from outside the east coast:

Just got back home from #RailsConf - what a great conference. It was great to see familiar faces and meet up with old as well as new Ruby friends. I miss you all! Can't wait till we all get the chance to hang out again

Beyond performance work, I deprecated a bunch of APIs in the JSON gem, and added others, so I figured it would be a good occasion to talk about API design: byroot.github.io/ruby/json/2025…
