Why the SDLC Is Cracking Under the Weight of AI
Why the SDLC Is Cracking Under the Weight of AI Three decades of engineering orthodoxy and the shift no one is talking about clearly enough I've been thinking a lot about a specific kind of organizational irony that I'm watching play out across engineering teams right now. A company buys into the AI productivity narrative — they roll out GitHub Copilot, or Claude, or some combination of both — and for the first two weeks, developers feel like superheroes. Code that used to take a da

Why I Stopped Ignoring Position Size (and What It Taught Me About Stops)
Why I Stopped Ignoring Position Size (and What It Taught Me About Stops) Quick context (why you're writing this) Here's the thing: I spent a whole weekend back‑testing a shiny mean‑reversion strategy on EUR/USD. The equity curve looked like a rocket ship — until I looked at the trade‑by‑trade P&L and saw a single 3% loss wiping out two weeks of profit. I was shocked. Turns out I was sizing every trade at a fixed 1% of equity, regardless of volatility, and my stop loss was a static 5
I built a free alternative to CodeCrafters, because it's 2026 and I'm done paying to learn
I'll be upfront: I love the CodeCrafters idea. Building real systems from scratch instead of grinding another tutorial is genuinely how a lot of this stuff finally clicks. But every time I went to commit, the price stopped me cold. And somewhere around the tenth time I closed that pricing page, I had the obvious thought: it's 2026, why am I being asked to pay this much just to learn by building? So I built the thing I wanted instead. It's called Ship That Code, it's run under my company Echoed L
Frontend System Design Interviews: What They Are, Why They Matter, and How to Actually Prepare
For mid-to-senior developers who want to stop winging it. If you've been a developer for 3+ years and you're targeting senior roles, there's a round in your upcoming interviews that will either make or break your offer — and it's not the LeetCode round. It's the Frontend System Design interview. Most developers underprepare for it. Some don't even know it exists until they're sitting in one. And if you're in the "I'll figure it out in the room" camp — this post is especially for you. The market

Prélakay: How I decided to build the digital infrastructure Haiti was missing Haiti receives over $5 billion in remittances every year. And yet — nobody knows where to buy local. A few months ago, I had a conversation that haunted me. My cousin in Montreal wanted to send money to her mother in Port-au-Prince. Not dollars through Western Union. She wanted to buy her something specific — an electronic device, a particular product. She wanted to support a Haitian seller. She wanted the money to
I built a free energy calculator site with plain HTML/CSS/JS — here's what I learned in week 1
I launched EcoEnergyCalc last week — a collection of 20 free calculators for homeowners who want to reduce energy costs and carbon footprint. Solar savings, electric bills, carbon footprint, water usage, heating costs, and more. Pure HTML/CSS/JS — no framework, no build step That's it. No React, no Next.js, no database. Every calculator runs client-side with zero backend. Canonical URLs on every page Week 1 Numbers 57 users (all direct — friends and community posts) The indexing is the bottlenec
