I'm a software engineer, founder, and educator who enjoys turning complex technical problems into useful products—and making the lessons accessible to other developers.
- 🚀 Founder of Teachyst — helping educators and creators host, brand, and monetize their courses on their own domains.
- 🎙️ Building Vidyst — a live streaming, webinar, and recording platform designed to make hosting online events feel effortless.
- 🎥 Teaching 426K+ developers through YouTube, with practical tutorials on backend engineering, full-stack development, DevOps, system design, and AI.
- 🤖 Exploring AI agents, agentic workflows, and developer tools—with a focus on products that solve real problems.
- ⚙️ Interested in distributed systems, real-time communication, cloud infrastructure, and scalable backends.
- ✍️ I learn by building, share what I learn, and believe great engineering should be understandable.
My philosophy: Build things that matter. Understand how they work. Share what you learn.
I especially enjoy working across the stack: from product interfaces and APIs to databases, queues, cloud deployments, media pipelines, and real-time infrastructure.
