What our clients and partners say
Working with Sebastian and his team was a real game-changer. Targeted AI automation saves us several hours per week, while at the same time raising the quality of our consulting work. A clear recommendation for anyone looking to future-proof their business.
Sebastian is a very structured and thorough developer. He is highly experienced and not only excelled in his tasks but could also offer valuable strategic advice.
For automation, I deliberately pick partners who think with us, not just tick off tasks. The Antigua team first looked closely at our workflows, then built a lead-automation that brings noticeably more qualified inquiries. It saves me at least one day a week.
As a family business, there's little time for routine tasks. Sebastian and Esra built us an AI solution that prepares response drafts in German and English and reminds about review requests. It saves several hours per week, and I have more time for my guests.
In the room where it happens
We don't just follow the tech and AI ecosystem, we actively help shape it. From Google Cloud workshops to DevFest stages: we speak, organize, and contribute.
DevFest 2026
Talks and workshops on taking Gemini apps to production, with real latency and cost numbers. The demo: Backyard Barista, Esra's open-source multi-agent cafe game on Cloud Run.
Google Cloud Build with Gemini
Esra facilitated the three-hour hands-on track: developers took an AI agent from agents-cli to Gemini Enterprise Agent Platform, A2UI, and a deployed Cloud Run frontend.
Google Cloud Builders Day
Esra took the Google stage to present Flutter's role in the cloud-native ecosystem, alongside Google's developer relations team.
From the team
Articles, field notes, and talks on AI agents, Flutter, and what we learn in daily practice.
Human-in-the-Loop Agents in Pure Dart: Genkit, MCP and an Approval Gate on Cloud Run
A dispatch agent written fully in Dart: a Genkit flow, the back office behind an MCP server, and an approval gate so paid actions wait for a person.
I approved the order. Then my Genkit Dart agent forgot its own tool.
Why an approved MCP tool call failed only on restart, and the fix and regression test sent upstream to genkit-dart.
Building Agentic Apps with Gemini & Antigravity: Track 2 Field Notes
Four engineering takeaways from facilitating the App Builders track at Google Cloud Build with Gemini.
