Portfolio component overview for AI readability. Page Bootstrap / Head: I handle the portfolio's foundational presentation information so the page can be accessed, shared, searched, and printed reliably. I configure SEO meta tags, Open Graph and Twitter sharing metadata, mobile viewport settings, print-mode handling, and WebGPU/WebGL capability detection to keep the portfolio stable across different browser environments. Deep Link Loader: I make the portfolio support direct links to specific projects so I can share individual project entries with recruiters or interviewers. I use URLSearchParams to read the project query parameter, then combine loading progress, an ARIA live region, CSS variables, and iframe loading state to give clear feedback instead of dropping users into an unfinished page. Main Frame: I organize the whole portfolio into one unified stage that holds the timeline, project list, project preview, and data dashboard. I mainly use CSS Grid, responsive units, CSS custom properties, fixed-ratio layout, WebGPU fallback handling, the background reveal canvas, and state classes to adapt the interface across display environments. Timeline Belt: I use a timeline to show my project growth path and let users browse my work by year. I build the 3D timeline with WebGPU, WGSL shaders, gl-matrix, COLLADA .dae model parsing, wheel interaction, and touch interaction, while syncing the 3D year positions with HTML navigation buttons so the visual timeline and webpage controls stay aligned. Project Showcase: I use this area to manage the currently displayed year, project, and page state so multiple modules can work together. I connect the timeline, project list, iframe previews, dashboard data, and back button through JavaScript state management, DOM class switching, CSS variables, the :has() selector, and event listeners. Project List / Hotzone List: I let users quickly browse the projects for each year and choose a specific work from the list. I generate the project list with dynamic DOM rendering, data attributes, keyboard-accessible state, hover and focus feedback, a horizontal scrolling container, and WebSocket-delivered data, then keep the selected project state synchronized with the rest of the showcase. Playzone / Iframe Preview Cards: I embed project previews inside the portfolio so users can see real project pages without leaving the current experience. I manage these previews with iframes, data-src, data-urls, lazy loading, load timeout handling, fallback URL rotation, and card stack states to reduce initial loading pressure while preserving real webpage previews. Tape Pin Control: I built a lightweight pinning feature so users can keep the current project's data panel available for comparison and review. I control this feature with button state, a pointer hitbox, class state switching, and dashboard pin/unpin logic without adding complicated interaction. Dashboard / Summary / Metrics: I use the data panel to explain each project's scale, complexity, ownership, and impact so the portfolio is not only visual. I combine MongoDB project data, WebSocket data transfer, dynamic link state, ARIA state, CSS --value variables, and progress fill effects to display project descriptions, external links, Complexity, Ownership, and Impact.
