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 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.

Cover image for 🚀 Introducing LunaOS
After months of

🚀 Introducing LunaOS After months of planning and development, I'm excited to share the vision behind LunaOS—a custom operating system being built entirely from the ground up. This isn't another Linux distribution. The goal is to build every core layer ourselves, including: • 🖥️ Custom Kernel • ⚙️ Custom Init System • 📦 Custom Package Manager • 🧠 Local-First AI Integration • 🎨 Modern Cyberpunk-Inspired Desktop Experience • 🔒 Privacy-First Architecture • ⚡ Performance-Focused Design LunaOS is being built around a simple philosophy: Own Every Layer. Instead of relying on existing operating system foundations, we're exploring what a truly modern, AI-native operating system could look like—one designed for developers, creators, and power users from day one. This is still the beginning, and I'll be sharing the journey publicly as LunaOS evolves. I'd love to hear your thoughts and connect with others interested in operating systems, systems programming, kernels, AI, and open-source software. #LunaOS #OperatingSystem #SystemsProgramming #KernelDevelopment #OpenSource #Linux #ArtificialIntelligence #LocalAI #SoftwareEngineering #SoftwareDevelopment #Developer #Programming #BuildInPublic #CyberSecurity #Innovation #TechStartup #ComputerScience #FutureOfComputing

Cover image for Lessons in Designing MCP Tool Names and Descriptions

What I learned building MCP servers for LinkedIn, Medium, Kaggle and X Over the past year I've open-sourced a series of MCP servers that let AI assistants like Claude work directly with LinkedIn, Medium, Kaggle and X. The biggest lesson had nothing to do with the APIs. It was how the tools are described. Three things made the clearest difference to whether an agent picked the right tool: - Action-first names like search_posts or get_profile, instead of vague ones like posts or query. - Descriptions that say when to use a tool, not just what it does. - Short, precise parameter docs with examples of valid values. With those changes, wrong tool calls dropped noticeably and agents needed far fewer retries. If you're adding AI agents or LLM features to your product and want them to work reliably in production, I'd be glad to help. Code: github.com/Dishant27

Cover image for I just opened a service

I just opened a service for teams who need a clean, isolated AWS environment - done right the first time, with Terraform so it's actually reproducible (not a pile of manual console clicks only one person understands). What I set up: ✅ Isolated staging/prod environments (proper VPC structure) ✅ IAM roles with least-privilege access ✅ Everything in Terraform — version-controlled, documented ✅ A handover doc so your team isn't locked to me Background: 12+ years in backend & cloud engineering, hands-on with AWS (Lambda, API Gateway, EC2), Docker, and Linux infra. If your AWS environment feels fragile, undocumented, or "nobody really knows how this was built" — that's exactly what I fix.
