My story.
I'm Trung Lập (Luci). I engineer high-performance systems. Over five years specializing in Flutter, I've shipped production applications across Android, iOS, macOS, Windows, and Web, backed by robust Go microservices and automated Python pipelines.
I operate across the entire product lifecycle. Architecture. State management. Real-time infrastructure. CI/CD. I build systems that scale, from a zero-knowledge encrypted diary to a live Web3 messaging platform with integrated on-chain wallets.
I am also a visual artist. That discipline strictly dictates how I approach visual hierarchy, proportion, and interface logic. My design decisions are deliberate. Nothing is accidental.
My baseline standard is production-grade stability. No fragility. No deferred technical debt. I execute with clean architecture, rigid state management, and an absolute obsession with edge cases. Ship. Refine. Repeat.
