My Passions

Tech Discussion

I actively engage in conversations around AI, blockchain, and emerging technologies, often through Twitter/X spaces and async discussions. I enjoy breaking down complex ideas, exchanging perspectives with other builders, and staying close to the edge of innovation, especially in areas like agentic systems, onchain economies, and decentralized infrastructure

Football

Football is one of my favorite ways to stay active and competitive outside of tech. I regularly play casual matches with friends on weekends. It’s a mix of fun, intensity, and just enough rivalry to keep things interesting. Playing football keeps me sharp physically, but more importantly, it reinforces teamwork, positioning, and quick decision-making under pressure. All of which translate surprisingly well into building products and systems.

Dota 2

I’ve spent a good amount of time in Dota 2, where strategy, mechanics, and mental discipline all collide. If you know Dota, you know it’s not just a game — it’s a mindset. Every match is a constant trade-off between risk and reward, map awareness, and timing. Some games feel like controlling chaos whether you’re making space as an initiator, scaling as a carry, or reading the map like a support. That constant decision-making loop is what makes Dota endlessly engaging. It’s also taught me resilience because sometimes, despite perfect execution, you still lose. And you queue again anyway.
