Build the servers, APIs, and databases that power applications.
Career · Capability
What you learn
- APIs designed as products other people can build on
- Data modelled for integrity, with migrations that are versioned and reversible
- Security at the seat where the attacks actually arrive
- Services you can operate, observe, and scale on evidence
What you will understand
- Every input treated as hostile before it touches your logic
- Transactions, isolation, and what guarantees you actually get
- Idempotency, because clients retry and duplicates are inevitable
- The monolith-first economics of when to distribute and when not to
How you will practice
- Design an API a stranger can call correctly from the contract alone
- Diagnose and eliminate an N plus one access pattern with before and after query counts
- Roll a migration forward and back cleanly on a populated database
What you will build
- A production service with authentication, authorisation, and an audit trail
- A gated pipeline where a bad deploy is rolled back within a stated time
The proof you build
Evidence that you can run services an organisation bets its product on, and prove they hold under failure.
Your work is observed with your consent, scored for independence and assistance, and turned into proof that carries a confidence level. The career path can reach a high-assurance credential, anchored by a scored capstone.
