WE BUILD
SYSTEMS
THAT HOLD.

Raw EVM infrastructure, production AI pipelines, cloud-native backends and the mobile & web products sitting on top. We go where generalists can't.

What we build

OUR FOUR
DOMAINS

Four disciplines. Each one goes deeper than a generalist shop. You work directly with the engineers.

01
01 / 04
BLOCKCHAIN& ONCHAININFRA

Raw EVM log correlation, Substreams pipelines, Subgraph protocols, and high-throughput indexing into ClickHouse and TimescaleDB. The engineering that powers institutional DeFi analytics nobody else gets right.

AI &AUTOMATIONPIPELINES

Production RAG pipelines with real cost engineering — not demos. Semantic search over millions of documents, LLM chatbots with proper auth flows, n8n automation. We cut OpenAI costs 70% in a live system serving 1,000+ daily users.

Technologies we go deep on

01
EVM Internals & Substreams

Raw 32-byte EVM word parsing, full transaction receipt correlation, multi-chain support across Ethereum, Arbitrum, Base, Polygon. Substreams in Rust/WASM, Subgraphs in AssemblyScript.

02
Rust Backend Systems

Async Rust with Axum and Tokio for high-throughput APIs, CI/CD orchestration engines, crawlers and data pipelines. Production-grade error handling, zero-downtime deploys.

03
RAG & Vector Search

End-to-end RAG pipelines: document crawling, chunking, embedding deduplication, pgvector HNSW semantic search, streaming LLM responses with subscription gating.

04
Flutter Mobile

Cross-platform Flutter apps for iOS and Android. Real-time Firebase sync, complex wallet flows, WebRTC audio/video, healthcare vitals, push notifications.

05
OLAP & Time-Series Data

ClickHouse Materialized Views, TimescaleDB hypertable partitioning, multi-hop token pricing. Sub-100ms queries on multi-TB DeFi datasets serving institutional clients.

06
Smart Contracts & DeFi

Solidity development, gas optimisation, NFT marketplace protocols. Protocol subgraphs for GMX, Uniswap, Pendle, Ribbon, Livepeer.

LET'S
BUILD
SOMETHING.

We take on a small number of projects at a time. If the problem is hard, we're interested. Blockchain, AI, mobile, cloud — or all four.
