You will get a production-ready Python API + async worker pipeline (FastAPI)
Project details
I will integrate your system with an external API using FastAPI and build reliable automation logic with secure credential handling, reconnect/retry logic, and error recovery. You’ll receive a production-ready backend endpoint, consistent data flows, and documentation so your automation runs smoothly with minimal maintenance.
This project is ideal for:
• Trading infrastructure backend integration (REST/WebSocket)
• Data ingestion and automation workflows
• Real-time monitoring and backend automation tasks
What you get:
• FastAPI backend with defined API integration
• Async or REST-based ingestion logic
• Secure handling of credentials
• Reconnect and rate-limit handling
• Basic logging and structured errors
• Deployment instructions (Docker/Cloud ready)

Next.js admin tooling — confidence-banded curation UI (2-week fixed-price sprint)
Matt shipped EXACTLY what he was hired to build, a confidence-banded curation UI for our admin tooling. He stayed inside his lane, brought his own dev branch and mock seed data so he could iterate without touching production, and made the admin workflow genuinely usable.
He was incredibly easy to coordinate alongside other engineers working on different parts of the stack at the same time.
Hire him. Would absolutely work with him again.

30 minute consultation
Matthew is exceptional. Deep expertise across financial markets (prediction markets and crypto included) paired with the ability to explain it all clearly. He found weaknesses in my trading setup I hadn't fully understood myself and laid out exactly how to address them. He's a great thought partner, genuinely engaged in shaping improvements together, and equally comfortable advising at a high level or doing the hands-on work himself. And frankly his background speaks for itself. Highly recommend.

My background is in trading infrastructure and quantitative systems at GETCO, Geneva Trading, Auros Global, and Epoch Americas. That work required software that could be tested, monitored, explained, and trusted when real money and real operations were at stake.
Today I help traders, funds, founders, and operating teams build or repair systems where the failure mode is not “we need more code.” It is bad data, fragmented workflows, unreliable integrations, unclear ownership, weak controls, or no record of what actually happened.
Common projects:
• Trading bots and execution systems
• Broker and exchange API integrations
• TradingView automation
• Market-data pipelines
• Backtesting and strategy validation
• Risk controls, order-state tracking, and position reconciliation
• CRM / client-data workflows
• API integrations and workflow automation
• Internal tools, dashboards, and operational reporting
• Evidence-gated systems that separate what works today from what still needs to be built
Recent work includes automated execution systems, DAS Trader-style risk automation, async fill handling, pre-trade risk controls, market-data infrastructure, backtesting frameworks, client-data workflows, and production API/worker systems.
Relevant proof:
• Production trading engine: single-writer order registry, idempotent fill handling, stale-fill rejection, and non-blocking async execution
• Quant research/backtesting framework independently audited A− / 92/100
• Market-data/API platform with ~68.6K lines of code, 1,230+ tests, 13 shipped products, and 42 API endpoints
• Evidence-gated operations platform where each workflow stage was validated with committed artifacts and operator runbooks
I work best with clients who need a system that is understandable, testable, monitored, and safe to operate—not just something that runs once.
I do not sell strategies, promise returns, or provide investment advice. I build the infrastructure, tests, controls, documentation, and execution paths needed to evaluate and operate workflows more reliably.
Send me what you are building, which systems need to connect, where the workflow is breaking, and whether you already have code. I will tell you the cleanest path to test it, fix it, or get it into production.
