→ cryptographic inventory & migration (NIST PQC, CNSA 2.0 deadlines)
→ LLM agents wired into real systems, not demos
→ end-to-end type safety across the stack (tRPC, Drizzle)| Project | What it does | Stack |
|---|---|---|
| tessera public |
Finds and inventories the cryptography across a codebase (source, dependency manifests, X.509 certs and live TLS endpoints), then emits a CBOM (Cryptographic Bill of Materials) with a quantum-risk rating per asset. Answers "where does RSA/ECDH/ECDSA actually live in our estate", which is the real blocker in post-quantum migration. | Rust CLI Next.js console open CBOM schema |
| Vantage private |
Real-time trading intelligence platform. Ingests world news, SEC filings, economic releases, on-chain flows, derivatives data and prediction-market odds into one live console, with a 3D event globe and AI-generated trading signals (direction, confidence, entry, TP/SL, sizing). Every signal is scored against outcomes, so accuracy is measured rather than assumed. | Python 3.12 TimescaleDB · Redis Next.js · Docker |
| look-and-mark public |
Realtime open-vocabulary detection and segmentation on a webcam feed, driven by a Claude agent that finds, marks and counts objects on request. Open-vocabulary, so the classes aren't fixed at training time. | Python computer vision agentic tool use |
| FastLaunchAPI product |
Production-ready FastAPI starter with authentication, Stripe billing and Docker wired up out of the box, so a new API ships in minutes instead of a weekend of boilerplate. | FastAPI · PostgreSQL Stripe · Docker |
| Dishpad private |
Restaurant management platform built as a Turborepo monorepo with end-to-end type safety from database to UI: shared packages, typed API contracts, no hand-written client types. | Next.js 15 · Fastify tRPC · Drizzle ORM Better Auth · Turborepo |
