A Manchester software studio building fintech systems — led by engineer Matthew Collins.
Fifteen-plus years of engineering, now focused end-to-end on high-performance market-data systems, AI-native workflows and blockchain infrastructure — Python & TypeScript, KDB-X/PyKX/q, RAG & vector search, and Solana/EVM smart contracts. Home of the Zero ecosystem.
Four disciplines,
one production mindset.
Hover a discipline — the consensus mesh behind this page re-routes to match. Every system below ships with observability, testing and compliance-aware design baked in.
KDB+/q & real-time market data
Tick architecture end to end — feedhandler, tickerplant, RDB/HDB, gateway routing — with TCA analytics: VWAP, TWAP, implementation shortfall, slippage and bps cost.
Smart contracts & consensus design
Solana/Anchor and EVM infrastructure, institutional Solidity libraries, enterprise DLT adapters, and an independently authored DAG-BFT consensus mechanism.
RAG pipelines & AI-native agents
Retrieval-augmented generation with local embeddings, token-aware chunking, citation controls, prompt-injection guards, golden-test evaluation and human-in-the-loop sign-off.
Full-stack product engineering
FastAPI/Node.js backends, Next.js/React frontends, PostgreSQL/TimescaleDB, Redis, Docker — instrumented with OpenTelemetry, Prometheus, Grafana, Loki and Tempo.
Flagship products,
built as complete vertical slices.
Strategy → architecture → backend services → data pipelines → dashboards → deployment → documentation. Every one of these is live or fully specified. See all work →
