Founder of Sizzy, a developer browser built for AI-assisted workflows. Developer, entrepreneur, and educator known for his energetic advocacy of “vibe coding”—collaborative development with AI that prioritizes natural interaction over syntax precision. Creator of React Academy, Benji, Zero to Shipped, and other tools.
Pioneer of Vibe Coding & AI-Native Development
Kitze (Kristijan Ristovski) has emerged as a leading voice in rethinking developer tools and workflows for the AI era. His philosophy challenges traditional notions of engineering: instead of fighting syntax rules, developers should describe their intent naturally and let AI handle implementation.
Current Work
As founder of Sizzy, Kitze builds specialized browser tools optimized for:
- AI-Assisted Development - Workflows where developers collaborate with language models
- Real-time Visual Feedback - Immediate visual output of AI-generated code
- Frontend Development - Responsive design testing and iteration
- Developer Flow State - Maintaining creative momentum while building with AI
His broader product ecosystem includes:
- Benji - Personal operating system for organizing thought and work (Life OS)
- Zero to Shipped - Focus on rapid execution and getting products to market
- Glink - Tool for keeping users in the loop
- React Academy - Teaching React and GraphQL worldwide
Philosophy: From Vibe Coding to Vibe Engineering
Kitze’s approach represents a paradigm shift in how we think about development:
Vibe Coding Principles:
- Natural communication over technical precision - Describe intent (“the vibe”) rather than write exact instructions
- Brain dumping as a superpower - The ability to articulate ideas quickly becomes more valuable than writing perfect code
- Iteration over planning - Rapid feedback loops replace upfront documentation and design
- AI handles translation - Language models convert developer intent into working code
Tools for the AI Era: As models improve, developer tools must be redesigned for human-AI collaboration, not just updated. Specialized browsers and interfaces that provide immediate visual feedback become critical infrastructure.
Community-Driven Learning: Kitze emphasizes staying current with rapid AI developments through active social media engagement. His observation “You have to be chronically on Twitter for this to work” reflects his belief that community discourse drives faster innovation than traditional documentation.

Conference Appearance
Event: AI Engineering Code Summit 2025 Date: November 21, 2025 Time: 12:20 PM - 12:39 PM Session: “From Vibe Coding To Vibe Engineering”
Kitze delivered an energetic talk demonstrating Sizzy browser and AI-assisted workflows through live demonstration. His presentation style featured cool visuals, product walkthroughs, and 4-5 minutes of rapid dictation-based development, positioning developers as “CEOs and architects of dreams” rather than just code writers.
Legacy & Impact
Kitze represents a crucial perspective in AI engineering: tools matter as much as models. His work challenges the industry to rethink not just workflows but the fundamental interface between developers and their tools. By building Sizzy specifically for AI-native development and advocating for more intuitive, conversational approaches to software creation, he’s actively building the future rather than critiquing the past.
