Overview

Introduction

Most FastAPI material stops at a single file and a uvicorn command. This course goes the whole distance: you design, test, containerise and deploy a quant pricing & risk API to AWS exactly the way a real engineering team does.

The service you build mirrors QuantIndex itself — a cloud-based, high-performing, scalable, AI-assisted and test-driven quant pricing and risk library, exposed as an API. You learn the architecture by building it.

It is a workflow course as much as a tooling course: test-driven development to keep pricing code trustworthy, infrastructure as code so environments are reproducible, and continuous deployment to shorten the loop between writing code and running it in production.

Hands-on

The project you'll build

You build one service end to end: a FastAPI application that values instruments and returns risk numbers. You start with repository structure and a tested application skeleton, then add validated pricing endpoints backed by the quant logic.

From there you containerise the service, provision AWS infrastructure with Terraform — VPC, ECR, ECS Fargate — and ship a first deployment behind a custom domain and HTTPS.

Part 2 makes it production-grade: a PostgreSQL database on RDS with migrations, a Redis cache for curves and results, async pricing jobs, end-to-end tests, monitoring and error tracking, autoscaling under load, a CI/CD pipeline, and AI-assisted endpoints.

Outcomes

What you'll learn

Production FastAPI

Structure a FastAPI service with routers, Pydantic models and services that scales past one file.

Test-driven delivery

Write endpoints test-first with pytest and FastAPI's TestClient, enforced by quality gates.

Containerisation

Package the service in Docker with small, reproducible, production-ready images.

Infrastructure as Code

Provision AWS VPC, ECR and ECS Fargate with Terraform — no clicking in the console.

Cloud deployment

Deploy behind HTTPS on a custom domain, then iterate safely with feature flags.

Data & caching

Add AWS RDS PostgreSQL with migrations and a Redis cache for curves and results.

Scale & observability

Autoscale under load and wire up monitoring, logging and error tracking.

Continuous deployment

Build a CI/CD pipeline that lints, tests and ships every change automatically.

Before you start

Prerequisites

  • Comfortable with Python — functions, classes, virtual environments.
  • Basic web concepts: HTTP methods, status codes, JSON.
  • Git fundamentals (clone, branch, commit, push).
  • An AWS account — the course uses small, low-cost resources and shows how to clean them up.

Fit

Who this course is for

Quant developers

You write pricing code and want to ship it as a reliable, scalable service.

Backend engineers

You know Python and want production FastAPI and AWS deployment patterns.

Data & platform teams

You support quants and want a reproducible, test-driven delivery pipeline.

Engineers entering finance

You want a realistic, cloud-native quant project to build and show.

Faculty

Your instructor

QuantIndex Faculty

QuantIndex Faculty are practising quantitative analysts and platform engineers who build and operate cloud-native pricing services. This course is written and reviewed by the team behind QuantIndex's own scalable pricing and risk API.

Benchmarked & verified

Every price you compute is checked against published results from leading textbooks and market data. You do not finish the course hoping your model is right — you finish it knowing.

Questions

Frequently asked questions

Do I need prior AWS experience?

No. The course introduces each AWS service as it is used and shows the Terraform that provisions it. You do need an AWS account.

Will this cost much on AWS?

The course uses small, low-cost resources and shows you how to tear everything down. Expect only a few dollars if you clean up as instructed.

Is it really a quant course or an engineering course?

Both. The project is a quant pricing & risk API, so the examples are pricing endpoints — but the focus is the engineering: testing, infrastructure, scale and delivery.

Does every lesson include code?

Yes. Each lesson pairs the theory with working Python you can run locally before deploying.

What do I receive?

Twenty-six lessons across two parts, the full source for the service, the Terraform, and the CI/CD configuration.

Is there a refund policy?

Yes — a 14-day, no-questions-asked money-back guarantee.
