Cover image for Full-stack Business Platform: Seamless Deployment with Biziffy

Just shipped a full-stack business listing platform — Biziffy. Built with React/Next.js on the frontend and Node.js/Express on the backend, deployed on a Hostinger VPS (Ubuntu 24.04) with PM2 and Nginx. Key things I handled on this one: Google Location API integration for accurate business listings, pincode validation, sitemap and robots.txt setup for SEO, and complete VPS deployment from scratch via SSH. The part I enjoyed most — getting the deployment pipeline clean so the client could manage updates without developer dependency.

Cover image for PayU Latam Payment Gateway Integrate

PayU Latam Payment Gateway Integrate Developed a complete PayU Latam payment gateway integration for Walon Sport (Peru), enabling users to complete transactions directly within the website without any redirection. The project included implementing multiple payment methods such as Credit/Debit Cards (Visa, Mastercard, Amex, Diners), Yape (mobile payment flow), and PagoEfectivo (CIP generation). A custom accordion-style checkout UI was built to improve user experience and guide users through payment selection. Additionally, a fully customized Thank You page was developed to display CIP codes and provide voucher access for offline payments. The integration was deployed in a production environment with AWS security layers (WAF), ensuring stable and secure payment processing. This project involved real-world API handling, debugging payment flows, and optimizing checkout UX for better performance and reliability.

Cover image for AI Viral Story & Cinematic

AI Viral Story & Cinematic Shorts Factory AI Viral Story & Cinematic Shorts Factory is a futuristic AI-powered storytelling workflow built entirely inside Melius. The project explores how AI can transform a single emotional idea into a complete viral-ready cinematic production pipeline for platforms like YouTube Shorts, TikTok, Instagram Reels, and Pinterest Video Pins. Using interconnected AI agents and advanced visual workflow nodes, the system handles: Trend research and viral analysis Emotional story generation Cinematic scene breakdowns AI image prompting AI animation direction Camera movement planning Voiceover scripting Music and sound design Thumbnail optimization Captions and hashtag generation Engagement prediction Multi-platform export workflows For the core demonstration, I created a 6-scene emotional rescue story following an abandoned puppy in the rain. The workflow visually demonstrates how a raw emotional concept evolves into a fully cinematic short-form narrative through interconnected AI systems. The project was designed to feel like a next-generation AI filmmaking operating system — combining storytelling psychology, prompt engineering, cinematography logic, emotional optimization, and creator workflow automation into one connected visual canvas. My goal was to explore the future of AI-native filmmaking and demonstrate how creators can generate production-ready emotional content in minutes instead of weeks. Process: Researched emotional viral storytelling formats Designed a multi-agent cinematic workflow architecture Built interconnected AI production nodes inside Melius Generated a full 6-scene cinematic narrative Created image and animation prompt systems Added voiceover, music, and sound design logic Built thumbnail, caption, and engagement optimization systems Produced a cinematic walkthrough showcasing the workflow Feedback on Melius: Using Melius felt like directing an AI-powered creative studio visually instead of switching between disconnected tools. The node-based workflow made it easier to structure cinematic storytelling pipelines, iterate on ideas, and connect production systems together in a much more intuitive way.
