Software that ships. Systems that scale.

Backend & distributed systems

High-throughput services, real-time APIs, event-driven architectures. Backends that stay fast and predictable under load, built in Rust or TypeScript so your team can own them long-term.

Data infrastructure

Pipelines, warehouses, and streaming platforms: ClickHouse, Kafka, Postgres and friends. From raw events to the numbers your product serves, wired for scalability and correctness.

Blockchain & onchain systems

Smart contracts and the infrastructure around them: indexing, market data, and the offchain services that keep onchain products fast and correct.

Consulting & fractional CTO

Architecture reviews, technical due diligence, hiring help, and a senior voice in the room when decisions get expensive.

End-to-end product builds

From idea to production: design, engineering, deployment. You get a working product in front of users, not a prototype and a handover document.

Senior only

The person you talk to on the first call is the person who designs the system and writes the code. Nothing gets handed down.

Small surface, no bloat

We keep systems boring and small enough to reason about. Fewer moving parts means fewer surprises and fewer 3am pages.

Direct and async-friendly

No account managers, no status theatre. Short written updates, working software every week, and a straight answer when something is off.
