Ashes Born builds graph-based retrieval systems in TypeScript: a GraphRAG engine over PostgreSQL, MCP servers that expose it to agents, and the evaluation harness that keeps the numbers honest. Every answer returns the page it came from.
Five pieces of work that can be opened and checked. Each card names the scope, the stack and one result; nothing here is a claim you have to take on faith. Read the case studies in full, or start with the FAQ.
A GraphRAG engine in TypeScript: markdown-aware ingestion, a knowledge graph in PostgreSQL with pgvector, Leiden community detection, and hybrid retrieval that returns the source behind every answer.

Research intelligence with a page reference on every edge: filings, permits and papers turned into a queryable relationship graph, delivered as HTML, PDF and a machine-readable evidence file.

The retrieval engine sold by the call instead of by the seat: an MCP endpoint with x402 pricing that settles in USDC on Base.

Before the retrieval engine: the interface layer. Campaign dashboards built to survive a launch day, rule engines that decide what a user can see, and test suites that run on every diff.
CAPABILITY
Low-code dashboards for campaign rooms: three.js and D3 components configured by non-engineers, wired to live data, and arranged by dragging.
CAPABILITY
Configuration that decides what a user can see and do, parsed and executed without a deploy.
Each row links to the record itself. Nothing here asks to be taken on trust.
Built at JD (2019–2022) on the low-code platform and campaign dashboards, at Compass (NYSE: COMP, 2022–2025) on micro-frontends and the Salesforce rule and UI engines, and at Yellow (2025–2026) on a Web3 trading platform and its wallet integration.
