## What Went Well ✨
|
||||
|
||||
### 1. Modular Component Architecture
|
||||
**Impact:** High maintainability and reusability
|
||||
|
||||
The team successfully decomposed the resume preview into focused, single-responsibility components:
|
||||
- `ResumeHeader.vue` - Profile photo, name, contact
|
||||
- `ResumeSummary.vue` - Professional summary
|
||||
- `ResumeExperience.vue` - Work history with date formatting
|
||||
- `ResumeEducation.vue` - Education history
|
||||
- `ResumeAdditionalInfo.vue` - Skills, languages, certifications
|
||||
- `ResumeDownloadButton.vue` - FAB with print mode detection
|
||||
|
||||
**Why it worked:** Clear separation of concerns made parallel development possible and testing easier.
|
||||
|
||||
### 2. Rapid Architecture Adaptation
|
||||
**Impact:** Delivered better UX without major delays
|
||||
|
||||
Mid-epic, the team pivoted from two-column to single-column layout based on UX validation feedback. The modular design allowed this change without rewriting components.
|
||||
|
||||
**Evidence:** Stories 2-3 and 2-4 were revised to match new architecture, but implementation remained clean and on schedule.
|
||||
|
||||
### 3. Type Safety Throughout
|
||||
**Impact:** Zero runtime type errors
|
||||
|
||||
All components leveraged TypeScript interfaces from Epic 1:
|
||||
- `ResumeBasics`, `WorkExperience`, `Education`, `Skill`, `Language`, `Certification`
|
||||
- Props properly typed
|
||||
- Composable helpers (`useResumeData()`) provided type-safe data access
|
||||
|
||||
**Why it worked:** Epic 1's solid foundation paid dividends in Epic 2.
|
||||
|
||||
### 4. Print Mode Detection
|
||||
**Impact:** Ready for Epic 3 PDF generation
|
||||
|
||||
The `?print=true` query parameter and `.no-print` class were implemented early, ensuring seamless integration with Puppeteer in Epic 3.
|
||||
|
||||
**Evidence:** Download button correctly hides in print mode, page renders cleanly for PDF capture.
|
||||

|
||||
|
||||
## Challenges & Lessons Learned ⚠️
|
||||
|
||||
### 1. Mid-Epic Architecture Change
|
||||
**Challenge:** Tech spec initially defined two-column layout, but UX validation revealed single-column was better for the design template.
|
||||
|
||||
**Impact:**
|
||||
- Stories 2-2, 2-3, 2-4 required revision
|
||||
- Component names became slightly misleading (e.g., "sidebar components" that aren't in a sidebar)
|
||||
|
||||
**Root Cause:** UX validation happened after tech spec creation.
|
||||
|
||||
**Lesson Learned:** Run UX validation BEFORE creating tech specs to avoid rework.
|
||||
|
||||
**Action Item:** Add UX validation step to workflow between architecture and tech spec creation.
|
||||
|
||||
### 2. Missing Interface Property
|
||||
**Challenge:** The `image` property for profile photos wasn't in the original `ResumeBasics` interface.
|
||||
|
||||
**Impact:** Had to add it mid-implementation in Story 2-3.
|
||||
|
||||
**Root Cause:** Interface design didn't account for all design template requirements.
|
||||
|
||||
**Lesson Learned:** Review design templates thoroughly when creating interfaces.
|
||||
|
||||
**Action Item:** Add design template review checkpoint to interface creation workflow.
|
||||
|
||||
### 3. Inconsistent Story Context Usage
|
||||
**Challenge:** Stories 2-1, 2-2, 2-3 had story context XML files, but 2-4 and 2-5 did not.
|
||||
|
||||
**Impact:** Inconsistent documentation and context availability for developers.
|
||||
|
||||
**Root Cause:** Story context generation was optional and skipped for later stories.
|
||||
|
||||
**Lesson Learned:** Either generate story context for ALL stories or NONE (consistency matters).
|
||||
|
||||
**Action Item:** Decide on story context policy: always generate or never generate for small epics.
|
||||
|
||||

|
||||
|
||||
## Technical Debt
|
||||
|
||||
**Current Debt:** None significant
|
||||
|
||||
**Observations:**
|
||||
- All components are clean and well-structured
|
||||
- No shortcuts taken
|
||||
- Print styles properly implemented
|
||||
- Responsive behavior works correctly
|
||||
|
||||
**Debt Avoided:**
|
||||
- Resisted temptation to inline styles
|
||||
- Maintained component modularity
|
||||
- Kept TypeScript strict mode enabled
|
||||

|

|
||||
## Preparation for Epic 3: PDF Export
|
||||
|
||||
### Dependencies Status
|
||||
✅ **All prerequisites met:**
|
||||
- Resume preview page exists and renders correctly
|
||||
- Print mode detection (`?print=true`) implemented
|
||||
- Download button placeholder ready
|
||||
- `.no-print` class working
|
||||
- A4 container dimensions set (210mm × 297mm)
|
||||
|
||||
### Technical Prerequisites for Epic 3
|
||||
|
||||
**Required:**
|
||||
1. Install `puppeteer` package: `pnpm add puppeteer`
|
||||
2. Test local PDF generation
|
||||
3. Configure Vercel for serverless Puppeteer:
|
||||
- Add `@sparticuz/chromium` for Vercel deployment
|
||||
- Update `vercel.json` with function config
|
||||
|
||||
**Recommended:**
|
||||
1. Test print preview in multiple browsers (Chrome, Firefox, Safari)
|
||||
2. Verify font loading in headless mode
|
||||
3. Test PDF generation with varying content lengths
|
||||
|
||||
### Potential Risks for Epic 3
|
||||
|
||||
**Low Risk:**
|
||||
- Puppeteer setup is well-documented
|
||||
- Architecture doc has clear deployment instructions
|
||||
- Print styles already tested
|
||||
|
||||
**Medium Risk:**
|
||||
- Vercel serverless function timeout (10s limit)
|
||||
- Font loading in headless Chrome
|
||||
- PDF file size optimization
|
||||
|
||||
**Mitigation:**
|
||||
- Use Puppeteer's `waitForNetworkIdle` to ensure fonts load
|
||||
- Test with max content length to verify timeout
|
||||
- Monitor PDF file sizes and optimize if needed
|
||||
