5.3× fewer tokens · 122 tests · 1,321 videos unattended · 60+ data sources · 5M+ daily reads
| System | What is under the hood | Evidence | |
|---|---|---|---|
| 01 | Collie | A coding agent that lives on your computer — and can actually run it. Terminal, desktop, browser and iOS. Python · Swift · MCP |
Matched a comparable open agent on SWE-bench Verified using 5.3× fewer tokens — ~110K against ~588K per instance, metered at the HTTP boundary by a proxy I wrote. |
| 02 | VocalCode | VocalCode (also written Vocal Code) is local push-to-talk dictation for AI coding. Hold a configured key or mouse button, speak, and release; text is inserted into the active field in most desktop apps. Rust · sherpa-onnx · WebView2 |
VocalCode is available now for Windows and Apple silicon macOS, with signed/notarized installers, a 30-day full trial and a $4.99 one-time launch price. Official site: vocalcode.app. |
| 03 | Nestlyze | An AI buyer's agent for US homebuyers — a two-minute chat, then 24 matched homes with transparent valuations. FastAPI · PostGIS · pgvector · React |
Six domain agents fuse 60+ public sources; gradient-boosted valuation on a leakage-safe temporal split, served in ~10 ms. |
| 04 | Stay | Open-source, crisis-aware mental-health AI. 988 and Crisis Text Line escalation, conversations encrypted on the device. Next.js · Claude |
Every safety rule is bound to a behavioral test in CI — the policy runs, it is not a document. |
| 05 | dota-rl | A Dota 2 bot trained offline from high-MMR human replays — behavioral cloning into offline RL, the AlphaStar-Unplugged pattern. PyTorch |
1M+ replay frames. The live engine validates only; sanctioned Lua Bot API throughout — no injection, no memory reading. |
| 06 | Video pipeline | Whisper → LLM → a TTS cascade that degrades through three engines instead of failing a batch → FFmpeg → upload. Python · CUDA · systemd |
1,321 videos published unattended across 23 accounts, VRAM-coordinated against concurrent GPU work. |
| 07 | Cartek | The auto marketplace I co-founded in 2018 and ran engineering for until 2025 — marketplace, ML, payments and infrastructure from zero. Laravel · AWS · Stripe Connect |
Six engineers, 5M+ read requests a day at 99.9% uptime, on a double-entry ledger with Stripe Connect as merchant of record. |
| 08 | GPU systems lab | A local resource broker and a cloud control plane for heterogeneous GPUs — priority, preemption, per-client VRAM quotas, gaming-mode yield, capability-aware placement and lease-based claims. Python · NVML/CUDA · Cloudflare Workers · D1 |
122 tests across scheduling, recovery and API behavior; register → enqueue → claim → complete validated end to end. |
- colliehq/collie — the agent above. Local-first, cross-platform, one-click Windows installer.
- gpubroker — GPU resource broker with HTTP, Python and MCP interfaces.
- claude-voice — push-to-talk voice interface for Claude Code.
- stay — private, public-good mental-health companion.
- nestlyze-mcp — real-estate search and due diligence from Claude Desktop or Claude Code.
- Rapport — local dual-channel session transcription for therapists; microphone and system loopback separated, offline, signed.
Rust - Collie for iOS — a SwiftUI client that tails and drives agent runs from a phone.
- Doppel — pronunciation training where the native reference is your own cloned voice saying your own sentence.
- Across the stack. Interfaces, backend services, distributed control planes, ML pipelines and operations.
- Evidence first. Benchmarks are metered at system boundaries; safety policies run in CI; schedulers are tested through failure and recovery.
- Hardware-aware. A home lab spanning RTX 5090, 3080 and 1080 hardware is the test bed for resource management, observability and heterogeneous placement.
- Founder ownership. I have taken products from blank repository through customer-facing operation, payments and production support.
