I am a senior software engineer with a background in Electrical and Electronic Engineering. I have worked professionally in software development since 2015.

Outside work, I build open-source software through @drmhse, explore cloud infrastructure, and publish engineering field notes at DRM HSE.

Open-source API and SDK infrastructure for B2B and B2B2C authentication. AuthOS combines a Rust API, standalone Linux and Docker distributions, TypeScript SDKs, framework adapters, and an embedded web client.

A mobile-first AI code terminal for inspecting repositories, operating terminals, running coding agents, reviewing diffs, and shipping work from a phone, tablet, desktop, or browser. The public repository contains the Flutter client, documentation, screenshots, and web demo, while matching Linux backend binaries are available to everyone through GitHub Releases.

A small cross-platform OCR server for PP-OCRv6 detection and recognition. It uses the pure-Rust tract ONNX engine, verifies downloaded model weights, runs offline after the first model fetch, and uses LoRA fine-tuning for its optional structured-understanding model.

A local CosyVoice3 HTTP service I optimized to run 2.2× faster, reaching a faster-than-real-time RTF of 0.757 on Apple silicon. It keeps API state separate from a disposable model worker, runs the LLM stage in MLX while flow decoding and vocoding remain in PyTorch, and supports durable idempotent jobs, seed reproducibility, memory telemetry, and optional WhisperX verification.

A Flutter desktop interface for local developer-machine supply-chain checks using Perplexity's Bumblebee scanner. It provides scan controls, package inventory, exposure findings, diagnostics, history, and threat-catalog management.

• AuthOS — Rust authentication infrastructure, SDKs, adapters, deployment bundles, and documentation.
• AI Code Terminal — mobile-first Flutter client with publicly downloadable Linux backend releases for agent-driven development work.
• PP-OCRv6 server for Rust — pure-Rust OCR API with local model caching and a LoRA-fine-tuned structured-understanding model.
• FunAudio TTS for Apple silicon — CosyVoice3 service optimized to run 2.2× faster at RTF 0.757, with a hybrid MLX/PyTorch pipeline and disposable model workers.
• Bumblebee Desktop — desktop endpoint inventory and supply-chain exposure review.
• AuthOS Skills — source-verified agent skills for implementing and operating AuthOS.
• Local AI Field Guide — self-contained guide to local models, runtimes, quantization, hardware, RAG, and agents.

• Jules — native Flutter client for reviewing Jules sessions, agent conversations, and generated code changes.
• Filesystem MCP — Docker-isolated MCP server for controlled filesystem work and whitelisted commands.
• MRZ with OpenCV.js and Tesseract.js — browser-based extraction and OCR of two-line and three-line machine-readable zones.

• Hasura + GoTrue — GoTrue extension and Docker Compose deployment that issues Hasura-compatible JWT claims.
• Phoenix 1.5.1 + Guardian — barebones Phoenix authentication example with a protected route.
• Hugo + Tailwind CSS + daisyUI — minimal starter with one development command for Hugo and Tailwind.
• Go REST starter — small starting point for Go APIs.
• Useful Linux commands — practical command notes collected from development and server administration work.

• Binance Spot Trading Bot — configurable Node.js spot-trading experiment with Docker, notifications, and a control UI. This is alpha software, not financial advice.

My personal projects currently explore:

• identity, authentication, and self-hosted infrastructure;
• Rust services, packaging, deployment, and operations;
• mobile-first developer tooling and agent interfaces;
• local AI, OCR, speech, and structured extraction;
• web applications and the systems required to keep them understandable and repairable.

The software spans Rust, Python, Django, JavaScript and TypeScript, Flutter, and PostgreSQL. My cloud infrastructure experiments use Docker, Kubernetes, Terraform, AWS, Nginx, Caddy, and GitHub Actions.

DRM HSE is where I document engineering decisions, experiments, failures, and repairs across software, infrastructure, AI, and electrical engineering.

• About Mike CK

My route into tech began with a Nokia phone in 2011, which gave me my first way onto the internet. I later moved to an Android phone and, with computer access still limited, wrote programs on paper and found a makeshift way to run C. A laptop came afterward; that is when I began building blogs, websites for local businesses, and mobile applications. I entered professional software development in 2015 and now work as a senior software engineer.
