Autonomous AI filmmaking for ad creative, where the evals are the product. A cloned voice and a generated avatar, alpha matting, and monocular depth on Apple Silicon warped into a 77-view light field, gated by 13 probes and 16 of 16 thresholds derived from labelled pass and reject pairs so it runs with nobody watching.

Multi-agent causal simulation of 1,000 AI-agent couples in Rust (Bevy ECS) and Python. Randomized controlled trials on agent memory with bootstrap CIs, permutation tests, placebo and counterfactual twins, and SHA-256 replay. A React and PixiJS 2D world, plus a Claude LLM that turns plain-language shocks into validated, deterministic inputs.

Know whether a change to your simulation actually caused the result, or was just luck. A reproducible randomized-controlled-trial harness for agent-based models with common-random-number twins, randomized arms, a byte-identical placebo, and fingerprint-verified replay, in Python, TypeScript and Rust with one identical fingerprint.

Real time drone AI for safe and adaptive flight that separates drift from hallucination. Multi agent reinforcement learning with Proximal Policy Optimization ("PPO") for path finding and coordination, served on a FastAPI backend with weight loading at startup, test isolation, and Docker deployment to bridge research into production

An autonomous ad pipeline that shoots with no director, grades pixels and audio instead of text, and picks a video engine for each audience. Multi-agent Python, ffmpeg, OpenCV and MediaPipe probes, LLM-as-judge, a hand-labelled golden set and eval-gated CI. The evals do all three, and it spends nothing until they pass.

WhatsApp's official API is Business-only and never touches your personal chats or groups. This wraps the WhatsApp Web protocol in a local HTTP API any client can drive: agents (OpenClaw, Claude Code), production AI, cron, curl. Deterministic enough to trust with a real account: dry-run default, gated mutations, queryable action IDs.
