💬 New: Ask my resume anything
This page ships a tiny Q&A widget you can talk to — 100% deterministic retrieval, powered by a 105 KB WebAssembly module (Rust + TF-IDF hashed embeddings). No LLM, no server, no hallucination. Try the floating chat bubble in the bottom-right, or paste this into any site:

Currently Learning
in-flight🦀 Rust + WebAssembly
กำลังศึกษา Rust จริงจัง — ownership & borrowing, traits, lifetimes, async, และ WebAssembly compilation target. เป้าหมาย: สร้าง systems-level software ที่ fast, safe, และ portable ไปได้ทั้ง browser, edge runtime และ CLI.
~106 KB WASM
— tokenizer, TF-IDF hashed embedding, retriever, 100%
deterministic, ไม่มีการเรียก LLM ภายนอก
🧠 Analytical AI Systems
สำรวจ deterministic / analytical AI patterns — MUX-Latent attention, hashed embeddings, IDF retrieval — ที่ให้ผลลัพธ์ predictable และ traceable กลับไปหา source ได้ทุก token. ทดลอง trade-offs ระหว่าง LLM-heavy กับ analytical retrieval ในโปรเจกต์ side.
