👋 Who Am I?

Experienced Flutter developer with 5+ years building cross-platform applications, skilled in FastAPI and ReactJS, conducting innovative research combining blockchain, AI, and mental healthcare for secure psychological consultation systems.

I obsess over clean architecture, offline-first experiences, and AI-augmented systems — from a 500K-install audiobook app, to IoT smart meters, to a blockchain-secured mental health platform.

By day I ship production code. By night I publish open-source Flutter packages and contribute to IEEE research on AI × Mental Health.

"The best code is the code that works for someone who needs it."

Project Pull Request Description Status
redhat-developer/lsp4ij #1445 Problem: lsp4ij was hardcoded to read language server messages only from a standard input stream — making it impossible to integrate language servers that don't follow the standard stdio protocol. Developers were completely stuck, forced to bypass the entire extension system with dirty workarounds just to get their server working.

Solution: Cracked open the pipeline. Plugins can now plug in any message source they want — a queue, a custom socket-based source, a legacy protocol proxy, anything else you can implement with a MessageProducer — cleanly, through the official API. What was once a brick wall is now an open door.

This single change unlocks an entire category of language servers that were previously incompatible with lsp4ij — without touching a single existing test or breaking any existing behavior.
