Vibe Coders Croatia #1 powered by Reactor Studio
Details
Meetup #1 for Vibe Coders Croatia — a community for builders who ship. No gatekeeping, no corporate stiffness. Hosted at Reactor Studio with two talks: Ivan Horvat on the agentic multi-repo workflow behind a real mobile app — specs, Figma via MCP, cross-repo issue dispatch, daily status sync. Ivan Klarić on The Solow Paradox of AI in Software Development — twenty years of building software and the teams that ship it (Google Search, Superbet, Cognism), freshly turned consultant, with a framework for measuring AI's real impact beyond raw velocity. Food, drinks, and the hallway conversations where the next side project starts.
📣 From Specs to Production: An Agentic Multi-Repo Workflow
A look at how we use AI coding agents as team members across the entire product lifecycle — from writing product specs and designing in Figma via MCP, to automated cross-repo issue dispatch and daily status sync. One docs repo owns the "what and why," one app repo owns the "how," and agents bridge the gap — keeping two repos, multiple tools, and a GitHub Project board in sync without manual handoffs. This talk will walk through the real workflow behind a mobile app built in Reactor Studio, showing how AI agents brainstorm features, generate structured specs, dispatch issues across repos via GitHub Actions, and keep everything tracked automatically. Whether you're a PM, designer, or developer — you'll see how agentic workflows can remove the glue work between your tools and repos.
Ivan Horvat is a full-stack software engineer with experience delivering product-focused web applications across frontend and backend. With a strong focus on building high-quality, user-centered solutions, he works closely with design and product teams to bridge the gap between idea and implementation. When he's not shipping features, he's exploring how AI coding agents can take over the boring parts of the development lifecycle.
📣 The Solow Paradox of AI in Software Development
Development velocity is the main metric used to evaluate AI's impact on engineering. After surveying freelancers, agencies, and large product organizations, we found that velocity is only part of the story — and for some teams, not even the most important part. This talk introduces a three-part framework for understanding AI impact across different types of orgs: velocity, completeness, and confidence. After summarizing and explaining these effects, we'll correlate them to existing research, turn them into actionable advice for engineers and their managers, and close with some speculation on where engineering teams — and software development as a discipline — are headed, based on the shifts we've already seen over the last year.
Ivan Klarić is a software consultant whose career quickly evolved from building software to building the teams that build it. He's worked across startups, scale-ups, big tech, product, and agency environments — co-founding a software agency with a few friends in 2007, spending five years at Google getting Search engineers to care about cross-cutting concerns like annotation quality and freshness, joining Happening/Superbet in 2019 for another five years building a sports engineering team that scaled Superbet from Romania-only to 5+ countries and millions of users, and a short stint at Cognism on a next-generation B2B sales intelligence platform. In early 2026, he joined the dark side and became an independent software consultant.
