How I Built a Multi-Agent Development System That Plans, Executes, and Remembers

Building software alone has a structural problem: context leaks between sessions, tasks drift, and knowledge disappears when you step away. This article walks through an architecture that solves it: a coordinator agent that orchestrates parallel sub-agents through structured research and planning stages, with all context persisted to flat files. The system runs autonomously - research, gap analysi...

Mastering Destructuring in JavaScript: Extract Smarter, Code Cleaner

Introduction Imagine checking through a cluttered backpack to grab just your keys, wallet, and phone; tedious, right? That's how grabbing data from arrays or objects feels without destructuring. Destructuring is JavaScript's elegant shortcut for unpacking values into variables. Since ES6, it revolutionized how we handle data, slashing boilerplate and boosting readability. In this post,...

Rust's Zero-Cost Abstractions, What Monomorphization Actually Does to Your Code

"Zero-cost abstractions" is one of Rust's core promises. You can write generic, composable, high-level code and the compiler will produce the same machine code as if you had written the low-level version by hand. Most people accept this claim and move on. It is worth actually understanding the mechanism behind it, because it has real consequences for compile times, binary size, and performance in ...

Frequency Hopping Spread Spectrum on LoRa SX1262: Making Radio Undetectable

LoRa is a remarkable modulation scheme. It achieves sensitivity below -140 dBm, delivers reliable links at distances conventional radios cannot reach, and does it all at milliwatt power levels. But LoRa has a weakness that is rarely discussed in maker communities: a standard LoRa transmission is trivially detectable. A fixed-frequency LoRa signal shows up on any spectrum analyser or SDR waterfall...

Python's Descriptor Protocol, The Feature Behind Everything You Use Daily

You use descriptors every day. Every time you write @property, every time you call a method, every time you use @staticmethod or @classmethod, you are using the descriptor protocol. Most Python developers have no idea it exists as a unified mechanism. Once you see it, you cannot unsee it. What a Descriptor Is A descriptor is any object that defines at least one of three methods: __get_...

The Go Memory Model, Why Your Concurrent Code Might Be Lying to

You write two goroutines. One sets a variable, the other reads it. You run it a thousand times and it works fine. Then it breaks in production, on a different machine, under load. You stare at the code and nothing looks wrong. It is not fine. You just got hit by the memory model. The Problem Is Not Timing, It Is Visibility Most developers think about concurrency bugs in terms of two o...

I Built Three Platforms for Dental Professionals — Here's What the Data Taught Me

I'm a software engineer who noticed that discovery in dentistry is completely broken. Dental professionals at small practices never see product reps. They pick labs based on word of mouth. Software vendors spam everyone with cold emails but there's no independent place to compare what exists. So I built three things to fix it. What I Built FreeDentalSamples.com — dental professiona...

🧠 AI is not replacing developers — it’s exposing the gap between them

The discussion around AI in software engineering is often polarized: AI will replace developers AI is just another tool Neither framing is particularly useful. What is actually happening is more structural: AI is raising the baseline of software development. The baseline is no longer a differentiator Activities that historically differentiated developers are becoming increasingly c...

I Reviewed 100 LinkedIn Headlines — Here's What Actually Gets Clicks

Your LinkedIn headline is 220 characters. That's it. And most people waste every single one of them. I spent a weekend going through 100 LinkedIn profiles — recruiters, developers, founders, job seekers, freelancers. I wanted to know: what separates a headline that gets profile views from one that gets ignored? Here's what I found. The 3 Headlines Everyone Uses (And Why They Fail) ...

How to Negotiate Your Salary Over Email (With Templates)

Salary negotiation is awkward enough in person. Over email, it's somehow worse — you're staring at a blank compose window, wondering if you sound greedy or desperate. I've been there. After helping dozens of people through job transitions, I noticed the same patterns: people who negotiate earn 10-20% more. People who don't leave money on the table every single time. Here's how to do it without t...

The Two Joys of Coding Before AI

There is a particular kind of grief floating around right now. You see it in blog posts, in conference talks, in late-night threads: a mourning for the joy of coding before AI. People describe it as if a forest has been paved over. Something they loved is gone, and something colder has taken its place. I think most of these conversations talk past each other because they skip the only question th...
