Cloudflare Workers Tech Talks in Hokkaido #2


Cloudflare Workers Tech Talks in Hokkaido #2

I hosted “Workers Tech Talks in Hokkaido #2” on June 3, 2026. It was the second Workers Tech Talks held in Hokkaido, Japan’s northernmost region known for its beautiful nature and delicious food. Following the success of the first event last September, we came back to Sapporo for another evening of Cloudflare Workers talks. More than 40 people joined, and the atmosphere was just as warm and enthusiastic as the first time. We had four talks covering a wide range of topics, from feature flags to GIS and AI agents.

What is Cloudflare Workers Tech Talks?

Cloudflare Workers Tech Talks is an event where developers who are developing using Cloudflare Workers talk about Cloudflare Workers. It has been held multiple times in Tokyo, Osaka, Kyoto, Niigata, Hokkaido, and Fukuoka. At the end of last year, we also held the first event in Austin, Texas! The feature of this event is that the speakers are free to talk about whatever they want. I often tell the speakers, “Please don’t give introductions like ‘What is Cloudflare Workers?’“. I ask them to talk about whatever they want to talk about.

Venue

The venue was again F-60 (エフロクマル) 9F, located in the heart of Sapporo — the same place where we held the first Hokkaido event. The 9th floor offers a great view of the city, and it’s a comfortable space that fits our group perfectly. Thanks again to MIERUNE for their support in making this event happen!

Attendees

We gathered participants through the event page on connpass.

We had 41 registrations, and many of them joined us on the event day, including several people from MIERUNE. For a second event in Hokkaido, it was great to see such strong continued interest in Cloudflare Workers.

Talks

Four speakers gave talks covering a wide range of topics, from Flagship to GIS, AI agents, and databases with Hyperdrive.

Flagship Story

ねこや

ねこや, a software engineer at ReMotive LLC. and MIERUNE Inc., talked about Flagship, Cloudflare’s feature flag service that recently entered public beta. He started by explaining what feature flags are and the different types of them. Then, he configured Flagship live while showing the Cloudflare dashboard, and finally demoed a simple app built with Hono to show the flags working in action. He has also written a detailed article about it.

Cloudflare GIS × AI Agent Development

西尾 悟

西尾 悟 (Satoru Nishio) presented about building a GIS (Geographic Information System) agent powered by AI on Cloudflare. He showed how Workers, Workers AI, Durable Objects, and Containers can be combined to let users interact with geospatial data through conversation — searching satellite imagery, running analysis like NDVI, and visualizing results on a map. At the end, he gave a demo that really wowed the audience: while chatting, the agent retrieved GIS information for a specified location and rendered it on the spot. It was fascinating to see GIS and AI agents come together on the Cloudflare stack.

Self-hosted DB with Hyperdrive

すばる

すばる (Subaru) talked about connecting a self-hosted PostgreSQL database to Cloudflare Workers using Hyperdrive. Working on a university timetable app, she migrated the backend to Hono and Workers while keeping her own PostgreSQL — chosen for flexible SQL-based search, with Japanese full-text search as something she wants to do in the future. She walked through the setup, from TLS encryption to binding the database with Hyperdrive for persistent connections and query caching. It was an ideal use case for Hyperdrive, which made it especially memorable.

Dynamic Workers

Yusuke Wada (me), gave a talk about Dynamic Workers. I introduced what Dynamic Workers is and some use cases including Code Mode. At the end, I demoed hono-eval and introduced Kakera, both built using Dynamic Workers.

Networking

After the talks, we had a social gathering where attendees enjoyed great conversations. This time, Tenshoku Draft, a service run by Livesense, kindly sponsored the drinks, providing two kinds of their original craft beer. Thank you to Tenshoku Draft! The networking session was a wonderful chance for everyone to connect and share their experiences with Cloudflare Workers.

Summary

The second Workers Tech Talks in Hokkaido was another great success! It was impressive to see more than 40 people join, and all four talks were a lot of fun. Originally, six speakers were scheduled to talk, but a typhoon on the day prevented two of them from making it, so we ended up with four. I hope the two speakers will get a chance to talk at another occasion! Even so, it was a thoroughly enjoyable event. Hokkaido has a vibrant tech scene, and events like this help spread Cloudflare adoption further in the region. Thank you to MIERUNE for supporting the venue, to all the speakers for sharing their knowledge, and to everyone who joined us. We look forward to the next one!
