About Me
I'm an AI-powered software engineer from Indonesia, focused on building intelligent web applications that solve real problems. My passion sits at the intersection of large language models, data pipelines, and modern full-stack development.
I've been building in public — shipping SaaS products like TrendPulse AI and VentureLens AI that combine real-time data, LLM-powered insights, and clean UI into tools that founders and businesses can actually use.
I'm self-taught and driven by curiosity. Every project is an opportunity to go deeper — whether that's integrating a new LLM API, designing a faster backend, or crafting a UI that feels effortless. I build with intention, and I ship.
