Specification

A workflow built for velocity and fewer excuses.

The stack stays practical. The goal is reducing friction between decision, build, and release.

  • Build stack
    • Next.js (App Router), TypeScript, React, and Tailwind for product-facing interfaces.
    • tRPC and Prisma for end-to-end type safety; FastAPI and async SQLAlchemy for Python services.
    • BullMQ + Redis for asynchronous pipelines, queues, and background AI tasks.
  • AI & LLM stack
    • Anthropic Claude SDK with LangGraph for multi-agent orchestration.
    • RAG with Voyage AI embeddings and pgvector for semantic search.
    • Evaluation harnesses for faithfulness, safety, and red-teaming before anything ships.
  • Infrastructure
    • PostgreSQL and Redis for persistence, caching, and queues.
    • Docker, Nginx + PM2, and Vercel for deployment.
    • Clerk for authentication and Stripe for billing.
  • Operating principle
    • Tools matter less than reducing friction between idea, decision, and release.
    • I optimize for leverage, not novelty for its own sake.
