How I Made My Portfolio Infinitely Extendable with 4 Lines of JSON

Adding a new project to my portfolio takes 30 seconds. No component changes. No new routes. No layout adjustments. Just 4 lines of JSON and an image dropped into a folder.I got tired of the typical portfolio maintenance cycle: build something cool, then spend an hour wiring it into your portfolio site, adjusting layouts, making sure the new card doesn't break the grid. So I designed mine to be completely data-driven from the start.Here's how it works. The Single Source of TruthEvery project

Why I Replaced All My useState with useReducer in My Real-World Project

Today I made a decision that changed the structure of my entire project.In my world-wise app, I replaced almost all useState logic with useReducer.Not because useState is bad.But because my app is no longer small.When your project grows, scattered state becomes messy.Multiple states.Multiple updates.Multiple dependencies.Harder debugging.And I realized something important:For real-world frontend applications,useReducer + Custom Hooks + API integrationis a powerful combination.

I Built a Framework That’s 17x Faster Than Laravel : Meet Kuppa.js

I Built a Framework That’s 17x Faster Than Laravel in One Weekend: Meet Kuppa.jsBuilding a web application often feels like a trade-off. You either go with a "batteries-included" framework like Laravel but sacrifice raw performance, or you pick a minimalist tool like Express.js but spend hours wiring up folders, auth, and database connections.This past weekend, I decided to stop choosing. I built Kuppa.js, an opinionated, high-performance framework built on top of Express.js, specifically

Building SwapShield: A Gasless & MEV-Protected Trading Analyzer using the Uniswap API

Decentralized finance (DeFi) trading is powerful, but it's not without its rough edges. Between unpredictable gas spikes, front-running bots (MEV), and failed transactions due to tight slippage, even experienced traders can get frustrated. What if traders knew exactly what route was optimal before they even signed a transaction? To solve this, we built SwapShield—a premium, open-source best-execution analyzer built entirely on top of the powerful Uniswap Trading API. The Challenge: Navigati

I Built 16 Free Dev Tools in a Week — Here's What I Learned

Last week I set myself a challenge: build as many useful, free developer tools as I could. No frameworks. No backends. No signups. Just single-page apps hosted on GitHub Pages.I ended up with 16 tools. Here's every one of them, what I learned, and why I think the "zero-backend micro-tool" model is underrated.

I Built a Free Trading Journal That Runs Entirely in Your Browser

Every trading journal I tried wanted me to create an account, hand over my trade data, and pay $15/month for the privilege.I just wanted to log my trades, see some charts, and figure out if I was actually improving. So I built TradeLog — a trading journal that runs 100% in your browser. No signup, no server, no data leaving your machine. The Problem with Existing Trading JournalsMost trading journals fall into two camps:Spreadsheets — flexible but ugly, no charts, easy to breakSaaS apps — p

One Array to Rule Them All: Designing Velnora's Unit System

v0.1 is tagged. The skeleton stands. And the original plan said v0.2 would be graphs — dependency graphs, project graphs, the whole resolution layer.But after researching it, I realized graphs are useless at this stage. There is no real workspace to resolve yet. No integrations to connect. The graph would just be a piece of code that does nothing because it has nothing to operate on. It would exist purely to satisfy the roadmap, not to solve an actual problem.So I skipped it. Graphs will come la
