Building EpicMint: A Full-Stack NFT Marketplace with AI and Web3

Web3 applications are often complex for new users. Creating wallets, minting NFTs, managing metadata, and interacting with smart contracts can quickly become overwhelming. I wanted to explore how modern web technologies and AI could make the NFT creation experience more intuitive. That led to building EpicMint—a full-stack NFT marketplace that combines Web3, AI, and a modern MERN architecture. T...

What a .NET Core service needs before it's actually production-ready

Health checks. Structured logging. Retry policies with jitter. Everyone who writes a "production readiness checklist" for a .NET Core service reaches for the same list, and none of it is wrong. But it's the wrong list to reach for first if your services live inside a shared domain model. I spent a chunk of this month wiring up something that's not on anyone's checklist: turning our domain project...

Building GovChain: Making Government Scheme Discovery Simpler with AI

Finding the right government scheme shouldn't require navigating dozens of websites or reading through lengthy eligibility documents. Yet for many students, professionals, farmers, and citizens, discovering relevant schemes is still a time-consuming and confusing process. To address this problem, I built GovChain, an AI-powered platform that helps users discover government schemes based on their ...

Build a Support Copilot That Loads the Runbook Before It Calls a Tool

An AI support demo can look finished after it answers one question and calls one API. The production tension appears later: the model has instructions, tools, customer messages, and credentials in the same context—but nobody can clearly say which part authorizes what. That is not just an AI problem. It is a systems-design problem hiding behind natural language. A reliable support copilot needs ...

I Built an AI Router That Decomposes Your Prompt and Dispatches to the Best Model

When you call an LLM API, you pick a model and hope it's the right one. Claude for reasoning, GPT for code, Gemini for long context... you're doing the routing manually. I got tired of this, so I built Flint — a smart routing engine that does the model selection for you. How It Works Instead of forwarding your prompt to a single model, Flint: Decomposes — analyzes your prompt and i...

AI Harnesses Are Just Middleware, and Middleware Trust Bugs Are Older Than Your Career

Here's the thing nobody wants to hear: we already know how to break systems where components blindly trust each other's output. We've known for twenty-five years. We just gave it a new name and forgot the lesson. Context An "AI harness" is orchestration glue. Take an LLM, wrap it with a bunch of connectors, plugins, and tool-calling scaffolding so it can actually do things (query a dat...

How I Built a Source-Tracked Game Wiki Network with Astro 5

Most early game wikis have a trust problem. Pages mix official facts, beta discoveries, trailer guesses, and community assumptions without telling readers what is actually confirmed. I wanted to fix that for the games I follow, so I built a small network of source-tracked game wikis with Astro 5. This post walks through the architecture, the content model, and the small tricks that make the whole...

5 macOS-on-Proxmox Bugs That No Guide Warns You About

Back in February I published a post about osx-proxmox-next, a tool that builds a macOS VM on Proxmox with one command instead of an afternoon of OpenCore plist editing. About 1,500 people read it. Some of them installed it. On hardware I don't own. That's when the interesting bugs showed up. 150 commits later, here are five failures that don't appear in any macOS-on-Proxmox guide I've found, wit...
