Modern React & Front-End Engineering Bootcamp Certificate

Checkpoint 1: Build a component hierarchy from a written UI model; use semantic HTML, reusable components and clear prop contracts rather than a single monolith.
Checkpoint 2: Add list rendering, events and local state; document where state lives and why derived values are not duplicated unnecessarily.
Checkpoint 3: Add forms with validation plus a real API/data flow; implement loading, empty, success and error states rather than only the happy path.
Checkpoint 4: Use effects only for external synchronization; demonstrate cleanup or race/error handling and explain one effect you deliberately avoided.
Checkpoint 5: Add TypeScript to component props, events and API/domain objects; resolve at least one type-driven defect or ambiguous contract.
Checkpoint 6: Run accessibility and performance checks, then deploy; document a before/after improvement and one production architecture/scaling decision.

Day 1: Choose a real user workflow; sketch routes/screens, component tree, state boundaries, accessibility goals and acceptance criteria.
Day 2: Build the static responsive shell and reusable components; verify semantic structure and keyboard-friendly interaction paths.
Day 3: Add state, events and forms; create edge cases for empty/invalid data and keep state ownership explicit.
Day 4: Integrate a real API or service; add effects/data fetching, loading/error behavior, cancellation or stale-response handling where relevant.
Day 5: Add TypeScript types and refactor weak contracts; add focused component/behavior checks and accessibility validation.
Day 6: Optimize bundle/render behavior where useful, run performance/accessibility audits and deploy to a production-like environment.
Day 7: Publish repo, deployed app, architecture/component map, typed interfaces, audit evidence, failure log, demo video and a product-facing README.
