Featured Projects
Here are some of my recent projects that showcase my skills and passion for development. Each project demonstrates different aspects of modern web development.
Company Profile Jasproland
FeaturedDeveloped a company profile website using Laravel 12 with MVC architecture, featuring clean and scalable code. The project included on-page SEO optimization (dynamic meta tags, semantic headings, XML sitemap, and speed improvements) to enhance search rankings, and an SMTP-integrated contact form for secure, automated admin email delivery.
Nexcent
This project was developed using React.js following a structured folder format, without relying on CSS frameworks like Bootstrap or Tailwind. It focuses on implementing core layout and styling from scratch, though it has not yet been optimized for responsiveness, hover effects, or animations.
Website of Architects
A simple static website built as part of my frontend learning journey, created using only basic HTML tags such as <div>, <p>, <img>, and <button>. This project focuses on practicing structure and layout fundamentals without responsiveness.
Brawijaya Healthy Chatbot
Developed an AI-powered health chatbot on the Smojo AI platform, integrating NLP to interpret user symptom inputs and provide initial recommendations. Enhanced user engagement by creating an interactive quiz-style chatbot game covering health and general knowledge, while designing a responsive and intuitive UI/UX for seamless access.
Spatiall Peta Tematik
An interactive web application built with the Leaflet JavaScript library to visualize spatial data of DKI Jakarta. The project displays administrative boundaries, highlights population distribution for density analysis, and maps the spread of HIV/AIDS cases across different areas to support public health insights.
Rafii Yuuki Chatbot
Developed an interactive chatbot leveraging Natural Language Processing (NLP) and Large Language Models (LLM), implementing prompt engineering, data processing, and collection pipelines to improve accuracy. Built with Web Smojo AI, the chatbot features database integration, user management, and user metrics analysis to enhance performance and engagement.
