Syahril Arfian Almazril — Technical Portfolio

Engineering AI Systems, Scalable Software, and Data Architectures

---

---

Executive Summary

A production-grade, highly interactive portfolio application engineered to showcase technical expertise across Artificial Intelligence, Data Science, and Modern Software Engineering. Moving beyond traditional static documentation, this platform delivers an immersive, high-performance user experience powered by WebGL physics simulations, real-time data integrations, and an autonomous AI chatbot assistant.

System Architecture & Technologies

The repository is built on a modern, decoupled architecture designed for maximal performance, scalability, and maintainability.

Core Framework

• Next.js 16 (App Router): Leverages server-side rendering (SSR), static site generation (SSG), and advanced caching mechanisms for optimal content delivery.
• React 19 & TypeScript: Enforces strict type safety and modern reactive paradigms across 50+ custom UI components.

3D Graphics & Physics Simulation

• Three.js & React Three Fiber (R3F): Powers the core WebGL rendering engine.
• Rapier Physics: Integrates real-time, deterministic physics simulations (e.g., interactive 3D Lanyard and structural models).
• Custom GLSL Shaders: Utilized for bespoke background elements, including the Hyperspeed and warp effects.

UI/UX Choreography

• Framer Motion & GSAP: Drives complex, timeline-based choreographies, micro-interactions, and fluid page transitions.
• Tailwind CSS & Shadcn UI: Provides a scalable, utility-first design system utilizing robust Radix UI accessibility primitives.
• Lenis: Implements smooth, premium scrolling dynamics.

System Integrations & APIs

• Dual-LLM AI Chatbot Architecture: Integrates Groq (LLaMA 3.1) as the primary provider with an automatic failover to Google Gemini (1.5 Flash), utilizing retrieval-augmented generation context mapped directly from portfolio.ts.
• GraphQL & REST Pipelines: Consumes GitHub GraphQL for repository statistics and WakaTime API for real-time code telemetry.
• Next-Intl: Provides a complete bilingual experience (EN/ID) driven by client-side browser header detection.

Key Features

1. Interactive 3D Environments

Implements hardware-accelerated 3D models using @react-three/drei and @react-three/fiber. Features include a physics-simulated identification badge that responds to cursor velocity and window constraints in real time.

2. Autonomous Portfolio Chatbot

An intelligent conversational agent deployed via the /api/chat route. The system builds a dynamic context window from the static portfolio.ts database and processes natural language queries using a redundant Dual-LLM infrastructure.

3. Real-Time Telemetry

Dashboards across the platform retrieve and display real-time engineering metrics, utilizing authenticated GraphQL requests to GitHub (activity heatmaps, language breakdown) and WakaTime (coding hours, IDE preferences).

4. Interactive PDF Document Viewer

A custom-built document rendering engine utilizing react-pdf, allowing users to zoom, rotate, search, and download the resume natively within the browser application without relying on external plugins.

5. Performance Diagnostics

The application implements a usePerformance hook to evaluate client hardware capabilities in real time, automatically disabling intensive WebGL shaders and complex GSAP animations on low-power or mobile devices to preserve battery life and maintain stable framerates.
