Backend engineer at Hix.AI building agent orchestration, Rust sandbox filesystems, and editable PowerPoint rendering.

Message

At Hix.AI, I designed agent orchestration with subagents and versioned artifacts, adding Redis Streams workflows for approvals, pause and resume, and recovery after worker failures. I also integrated OpenAI and Anthropic APIs and built Google and Microsoft connectors across MCP services.

I built hix-fs, a Rust FUSE filesystem for E2B sandboxes, and a bidirectional HTML/PPTX engine that turns browser layouts into editable PowerPoint objects. For the renderer, I added visual regression checks and automated tests, and cut 20-slide template parsing time from 49.7 seconds to 10.7 seconds.

I rebuilt FileLoader to support more than 40 formats and per-page PDF extraction, raising load-test throughput from 60 to 500 requests per second. I also trained multilingual AI text detection models and optimized CPU inference and batching to reduce peak container memory and average latency.

In open source, I contribute to Go, gore, and other projects, including fixes to WebAssembly and platform-specific behavior. My personal projects include a Go binary size analyzer and a Linux/OpenWrt HTTP User-Agent rewriter.

llm-detect: Multilingual AI Text Detection

Hix.AI

Aug 2025 - Present (1 year 2 months)

Trained models for 13 languages. On held-out tests, detection/false-positive rates were 100%/0.20% for English and 94.17%/0.40% for Japanese. Optimized CPU inference and batching: peak container memory fell from 3,556 to 1,672 MiB (4 CPU/8GiB), and average latency dropped about 35% after deployment.
