BlackOrigin — Scalable Marketplace Trading Bot

A marketplace where traders discover, subscribe to, and run automated bots. RabbitMQ dual-queue separates execution from live streams. Real-time WebSocket feeds deliver PNL and signals with sub-second latency. Redis pub-sub handles state lookups across the bot engine.

How I Work

01

Discovery

I read your codebase or RFC before our first call. I come with questions, not a pitch.

02

Architecture

Map data flows, identify bottlenecks, propose the simplest solution that holds up at scale.

03

Build

Typed, tested, reviewed. I ship incrementally — working software weekly, not at the end.

04

Handover

Clean git history, deployment runbook, recorded walkthrough. You own it fully when I'm done.
