# epid.co - Mohammad Rahimi

> Full-stack developer and systems architect with 13+ years of experience building AI systems, real-time trading engines, blockchain infrastructure, and large-scale automation. Based in Turkey. Works task-based and spec-driven: you bring a spec and acceptance criteria, and the work ships production-grade - tested, deployed, and built to survive real load.

## About

Mohammad Rahimi (handle: epidco) is a solo systems architect who owns the entire stack, from the first line of code to production deployment. Background spans crypto infrastructure (a privacy coin, a mining operation, an exchange, and a pool), algorithmic trading (a real-time, event-driven tick processing engine written in Go with a dedicated strategy language), Web3 and smart contracts, AI agent systems, and dozens of live services on self-owned, containerized infrastructure with CI/CD.

## Services

- Trading infrastructure: execution engines, exchange connectivity, risk controls.
- Autonomous AI agents: multi-model agentic pipelines (Claude, Gemini) that ingest data, decide, and act across APIs.
- Data pipelines and automation: resilient crawling, normalization, and delivery at scale.
- Telegram ecosystems: bots, userbots, and VIP membership systems with automated crypto payment gateways.
- Web3 and dApps: token launches, staking protocols, and sleek React frontends.
