The site replaces a static 4-page PDF with animated SVG visualizations, a filterable career timeline, an AI chatbot, and a service offerings page. The project was built with **Next.js 15**, **Tailwind CSS**, **Framer Motion**, and **custom SVG visualizations** (no charting library). The AI chatbot runs on **Gemini 3 Flash Preview** via Google AI Studio with SSE streaming. The entire site ships with just 6 production dependencies and 158 kB of first-load JavaScript. Visual mockups and UI exploration were prototyped using **Gemini 3.1 Pro** for rapid design iteration before implementation, enabling high-fidelity design decisions without traditional design tools. 2 ## Tech Stack & Tools ### Core Framework & Libraries Layer Technology Purpose Framework Next.js 15 App Router, SSG, Turbopack dev server Language TypeScript 5.7 Type safety across all data and components Styling Tailwind CSS 3.4 Utility-first CSS with custom design tokens Animations Framer Motion 11 Scroll animations, SVG path drawing Visualizations Custom SVG Hand-built, no charting library AI Chatbot Gemini 3 Flash Preview Google AI Studio integration Design Mockups Gemini 3.1 Pro Rapid UI prototyping and visual exploration Analytics Vercel Analytics Page views and Web Vitals Contact Form Formspree Serverless form handling ### Development & Deployment Tool Purpose ChatPRD AI product management — helped draft initial PRD Codex AI research assistant — refined PRD structure and requirements Cursor AI-powered IDE — Plan Mode with Codex models Claude Code AI pair-programming — wrote majority of code Gemini 3.1 Pro Design mockups — rapid UI prototyping and layout exploration Git / GitHub Version control Vercel Hosting, CDN, SSL, custom domain ### What I Didn't Use (and Why) ✕**No charting library** — Custom SVG gave full control without bundle bloat ✕**No CMS** — Career data lives in TypeScript files. A CMS adds complexity without value. ✕**No test framework** — The site is entirely presentational. Visual QA was sufficient. ✕**No database** — Everything is statically generated at build time. **Key Insight:** The "no charting library" decision saved significant bundle size and gave pixel-perfect control over the Career Path visualization — including year-proportional node positioning, custom bezier curves, and per-node label placement. 4 ## Architecture & Design Decisions ### Page Architecture The site is a single-page scrollable app with additional routes: ``` / → Hero + Visualizations + Filters + Experience + Contact /collaboration → Service offerings, packages, working style /how-i-built-this → This case study /api/chat → POST endpoint for AI chatbot (SSE streaming) ``` ### Data Architecture All career data lives in typed TypeScript objects under `src/data/`: File Contents Records experience.ts Career entries, education, filter tags 8 entries, 7 tags skills.ts Skill categories, industry data, role nodes 7 categories, 77 skills offerings.ts Service offerings, packages, tools 10 offerings, 3 packages chatbot-knowledge.ts AI chatbot knowledge base, system prompt ~5K tokens **Why TypeScript over JSON?** TypeScript data files give type checking at build time. If you misspell a filter tag ID, the build catches it. JSON would require runtime validation. ### Z-Index Strategy Element Z-Index Position Sticky filter bar z-30 sticky top-\[68px\] FloatingNav z-50 fixed top-4 Chat widget z-\[60\] fixed bottom-4 right-4 Skip-to-content z-\[100\] Absolute on focus A ## Appendices ### Commit Timeline Date Hash Description Feb 8 fb6a036 Initial commit: complete interactive resume (Phases 0–7) Feb 8 34e5062 Phase 8: responsive design, accessibility, performance Feb 8 53bdd97 Fix post-launch UI issues Feb 8 47ba309 Merge Skills + Tech Stack into single tab Feb 8 18a2ea5 Add Collaboration page Feb 9 b5e26ea UI rework: year-proportional chart, timeline, nav Feb 9 2d65169 Company logos, full resume content Feb 10 78bb8f6 Deployment complete — live at dbenger.com Feb 10 1f47fd8 Mobile layout fixes Feb 11 4095704 Add case study page ### Source File Structure ``` src/ ├── app/ │ ├── layout.tsx Root layout (fonts, metadata) │ ├── page.tsx Home (Hero + Experience + Contact) │ ├── globals.css Global styles + Tailwind │ ├── api/chat/route.ts Gemini chatbot API (SSE) │ ├── collaboration/page.tsx /collaboration route │ └── how-i-built-this/ /how-i-built-this route ├── components/ │ ├── layout/ FloatingNav, Footer │ ├── hero/ HeroSection, 3 visualizations │ ├── experience/ ExperienceSection, ExperienceCard │ ├── filters/ FilterPills │ ├── contact/ ContactSection (Formspree) │ ├── collaboration/ OfferingCard, PackageCards │ ├── ebook/ EbookContent (case study) │ └── chat/ ChatWidget, TypingIndicator ├── data/ TypeScript data files ├── hooks/ useScrollAnimation └── lib/ Utilities, sanitization ```
