Welcome words from the organizers

7:35 PM: Building Low-Latency Voice AI with Go: Lessons from Production / Tom Arrell & Omar Davutoğlu @ Synthflow AI
Discover how Synthflow AI leverages Go's concurrency primitives and performance characteristics to build real-time voice systems that handle thousands of simultaneous conversations. We'll explore goroutine patterns for audio streaming, memory management strategies for low latency, and the trade-offs we've made scaling our voice agent infrastructure.

Tom Arrell - Principal Software Engineer at Synthflow AI in Berlin, where he specialises in building scalable distributed systems and voice AI infrastructure. A specialist in Go and Rust, Tom is driven by a philosophy of writing useful, modular, and well-architected code. Before joining Synthflow, he held senior engineering roles at SumUp and Klarna, working on high-volume backend services. When not debugging Go routines, Tom can often be found hacking on custom mechanical keyboards.

Omar Davutoğlu - Senior Software Engineer at Synthflow AI, where he architects infrastructure for autonomous voice agents. With a deep background in the programmable communications space, Omar previously served as a Software Engineer L3 at Vonage, working on core VoIP and communication platforms. His engineering experience spans multiple high-growth Berlin tech companies, including senior roles at Nuri (Fintech) and On, where he specialised in building resilient, distributed backend systems.

8:00 PM: Building GoVisual: Zero-Config HTTP Debugging in Go / Arif Dogan, Independent Tech Consultant
GoVisual is an HTTP debugging middleware used by 1,000+ Go developers.
In this talk, I'll share why Go debugging is painful, how we architected GoVisual
for zero-config integration, real production use cases (4hrs → 15min debugging),
and lessons learned building developer tools at scale.

Arif Dogan is a Independent Tech Consultant building high-performance Go systems in Berlin.
Creator of GoVisual (HTTP debugger for Go, 1,000+ developers), fastapi-radar, and LLMDog.
8+ years building backend systems at scale.
