Building "The Green Architect": An AI-Powered Sustainability Tool Just shipped a new feature for Project Bytenova! I wanted to build a carbon footprint calculator that doesn't feel like a tax audit. The Challenge: Standard calculators are boring and rigid. I wanted a UI that feels organic and "sketchy" (hand-drawn style), combined with the power of LLMs to handle complex, unstructured user inputs. Key Feature: Users simply type their daily routine or business operations in plain text. The AI analyzes the input, estimates the carbon footprint across 4 categories, and generates 3 custom "blueprints" to reduce it. Check out the slides to see the flow! ➡️ I'm currently open for new opportunities in Development or Collaboration. Let's work together!

DeepDay Landing Page Live Demo: https://deepday.vercel.app/

Building out the landing page for Kreativa Bandung using the new Astro 5 and React. As a Developer, I often see a trade-off between "flashy" animations and site performance. My goal with this project was to have both. The Tech Stack: - Astro 5: For that "Zero JavaScript by default" architecture. - React 19: Selectively hydrated for interactive islands (like the text reveals). - Lenis: For normalized, luxury-feel smooth scrolling. - Tailwind CSS: For keeping the style bundle tiny. It’s just a landing page for now, but it demonstrates how modern tooling can deliver premium experiences without the bloat. Check out the demo link in the comments! 👇

Excited to share the landing page design for KreativaBandung, a digital ecosystem connecting local creatives and startups.

Just finished Borobudur Learning - a fun EdTech landing page that shows what I can do. It's got an AI syllabus generator (pretty cool with Google Gemini), a chatbot tutor that actually helps users learn, smooth animations everywhere, and it works perfectly on any device.
