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)

Matthew is a highly creative and hard-working developer who excels in everything he works on. He delivered well ahead of the anticipated timeline with a high quality solution that is robust in both securty features, user experience, and performance. We would gladly hire Matthew again.

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.

This is my second project with Matthew. I can’t imagine a more thorough or competent programmer for my needs. He understands specs, is timely with communication, and honestly, he doesn’t miss. You will be lucky to hire this guy for your project.

My best work is turning messy business logic, external APIs, uncertain data, and high-risk workflows into systems that are observable, testable, deterministic, and safe to operate.
Clients hire me when the risky part is not “can someone code it?” but “will this behave correctly when real users, real money, real data, or real operations are involved?”
My best work is not generic app development. It is turning messy business logic, external APIs, uncertain data, and high-risk workflows into systems that are observable, testable, deterministic, and safe to operate.
Recent work includes:
• Django, FastAPI, and Python backend services
• React / Next.js admin tools and operator dashboards
• AI/RAG workflows with retrieval, grounding, and validation concerns
• API integrations, SDKs, telemetry, billing, and control-plane systems
• Quantitative modeling, Bayesian scoring, simulation, and validation
• Trading, market-data, and execution systems
• Architecture reviews, migrations, code audits, and production hardening
Clients hire me when the risky part is not “can someone code it?” but “will this behave correctly when real users, real money, real data, or real operations are involved?”
Recent Upwork outcomes include:
• Shipped a confidence-banded React/Next.js curation UI exactly to scope
• Delivered a Cloudinary / Sanity / WooCommerce integration POC ahead of schedule
• Built local Python simulation tooling with deterministic CSV-in / CSV-out workflows
• Completed trading and prediction-market consultations focused on weaknesses, execution risk, and system design
I work best in projects with real constraints: existing codebases, unclear state, brittle integrations, production pressure, model risk, operational handoff, or a need for senior technical judgment.
Good fits include:
• Fractional CTO / technical lead support
• Django / FastAPI / Python backend systems
• React / Next.js admin dashboards and operator tools
• AI/RAG reliability, evaluation, and workflow hardening
• Bayesian/statistical scoring, simulation, and model validation
• Trading, market-data, and execution infrastructure
• API integrations and data pipelines
• Architecture reviews, migrations, and codebase audits
I usually prefer starting with a tightly scoped milestone: audit the risky part, define the system boundaries, prove the first working slice, then expand from there.
