Service
Deployed API
A small Python service with tests, CI, and a container you can roll back.
Software Engineering Fundamentals
Testing, Git in a team, reviews, APIs, and a deployment you can roll back. The habits AI features fail without.
Created by Baljeet Dogra
Course Objectives
- Ship a small service with tests, a review, and a rollback path.
- Read a stack trace and a failing CI job without panic.
- Design a simple HTTP API and document the contract.
- Treat prompts and models as dependencies of a normal service.
What you will produce
Habit
Review notes
You sit as reviewer on a peer change and write what you would block on.
6 weeks curriculum
Expand a part for the syllabus. Content stays searchable when closed.
01 Git and the team Week 1
Branching, pull requests, bisect, and what never belongs in a commit.
- Branching
- PRs
- History
- Secrets
02 Testing that pays rent Week 2
Unit, integration, fixtures. What to mock. Coverage as a tool, not a trophy.
- pytest
- Fixtures
- Mocks
- CI
03 Reviews and design Week 3
How to leave a review someone can act on. When a design note beats another PR comment.
- Review craft
- ADRs in miniature
- Interfaces
04 HTTP APIs Weeks 4–5
REST, status codes, idempotency, auth headers, versioning. The model is just another client.
- Contracts
- Errors
- Idempotency
- Auth
05 Ship and roll back Week 6
Docker, health checks, logs, a rollback drill. Capstone: the service off your laptop.
- Containers
- Health
- Logs
- Rollback
Who this is for
Scientists becoming engineers
You can train a model. You have not had to own a service.
Self-taught Python developers
You ship scripts. You want the habits a team will trust.
Prerequisites
- Comfortable Python
- A GitHub or GitLab account
- You have run a program from the command line
Not a fit if
- Staff engineers looking for distributed-systems depth
- A management overview of “the SDLC”

Questions
Will we use Kubernetes?
No. Containers and a rollback are enough here. Kubernetes for AI Systems is a later course.
Do I need to have deployed before?
No. By week 6 you will have.
