Wowa Effect aka Wowa Barssukov revives the art of creating music with knowledge and analog instruments. His unique tracks originate from a combination of retro synthesizers, drum machines, and samplers. He transcends mood into music, no exact recreation possible when playing live; all sounds originated by hand. His debut performances were underground raves and house parties in 2018. His musical knowledge is based on classical Russian music education. Growing up in Siberia in the ’90s, his childhood was filled with communism, the sense of upheaval, and the upcoming of an underground raver scene. He started his electronic music journey under the name ‘Limpfate’ in 2017 first by creating his tracks with Ableton Live, until growing bored of the unengaging production. He then discovered analog synthesizers and drum machines, which shaped the sound of the electronic music scene in the ’90s, and spent countless hours on mastering the complex devices. This art of performing allows Wowa to explore the vast horizon of electronic music. Therefore his sounds vary from ecstatic electro over the groovy house to deep techno. His tracks take the listeners on journeys through the unknown, full of surprising details. When watching Wowa perform, you will notice a set of blinking lights, cables, and his straight face. When Wowa plays, it’s without exception, live. Wowa now lives in Berlin, close to the pulse of the original German techno scene with its renowned Berghain.

Gil Zilberfeld has been a software practitioner since the days of his Sinclair ZX81. With over 25 years of hands-on experience, he is a consultant, trainer, and speaker who helps development teams elevate their craft. Gil challenges conventional thinking about how software gets built - whether that's outdated QA dogma or the assumption that AI coding agents will just figure out your engineering practices on their own. He builds real systems with AI tools daily, and shares the honest lessons: what works, what breaks, and what needs mechanical enforcement no matter how smart the model gets. From TDD and clean architecture to AI-assisted development workflows, he provides actionable frameworks grounded in real production experience. You can find his practical advice and courses at testingil.com.

Wesley Fuchter is Director of Software Engineering at Modus Create, where he spends his time turning AI coding tool experiments into organization-wide practice. After leading a structured A/B experiment that demonstrated a 40% reduction in development time, his focus shifted to the harder challenge: getting a full engineering team to actually leverage agentic coding. His team built the knowledge-sharing systems, workshops, and practical resource libraries that are driving the shift. With 14+ years in cloud architecture, enterprise modernization, and engineering leadership across healthcare, fintech, and Fortune 100 organizations, Wesley brings a practitioner's perspective, including what didn't work. He holds the AWS Solutions Architect Professional certification and has previously spoken at worldwide tech conferences.

I've been the engineering manager and I've been the product manager. My work has taken me across news, streaming, energy trading, virtual reality, logistics - and organisations from startups to companies with over 20,000 people. I once worked around the technical limits of Apple News to get a newsroom to its launch. When I took over a failing team of nineteen, nobody left in the following year. Right now I'm focused on AI adoption in engineering teams - and on whether the advantage still comes from the tools, or from the people.
