sfroment - Overview

Hi, I'm Sacha

I'm a senior backend and distributed systems engineer based in Paris.

I mostly work with Go, Rust, TypeScript, and Python. I like building reliable systems: real-time backends, P2P networking, event-driven platforms, infrastructure tooling, and high-throughput APIs.

Recently I've worked on:

• P2P networking and distributed state sync with Rust, libp2p, QUIC, and CRDTs
• Real-time product systems with WebSockets, Kafka, and high-scale APIs
• Backend platforms on Kubernetes, AWS/GCP, Terraform, PostgreSQL, Redis, and gRPC
• Open-source, blockchain, and infrastructure projects
