We build products, modernize systems and put AI to work — from Florianópolis, Brazil, for companies in Brazil, the US, and Europe. bleu.builders
Most of our engineering is public. A sample of what we've shipped and maintain:
For CoW Protocol — 16+ initiatives over 30+ months around the core protocol: cow-py (Python SDK, built by Bleu and upstreamed to CoW), cow-programmatic-orders-api (live in production), cow-hooks-dapps, governance dashboards.
For Silo Finance — built the entire data layer, end to end: subgraphs, multichain APIs, liquidation infrastructure. Infrastructure costs cut 80%.
For Perk — the whole product team for 3+ years: 16 apps in production, including a global M&M's launch that reached 1.5M people at 99.984% uptime.
