How I packaged offline AI, Flask, and Cryptography into a single Python executable 🚀

If you have ever tried to share a complex Python project with a friend or a security analyst, you know the pain. You hand them the code, and within five minutes, their terminal is throwing errors about missing pip packages, conflicting library versions, or broken machine learning dependencies. As a Computer Science student, I recently ran into this exact wall while building my open-source digi...

GitHub Copilot AI Agents: The Secret to 10x Engineering in 2026

In this article, I’ll show you how to unlock the full power of GitHub Copilot agents inside VS Code. There are actually three main types of Copilot agents-most people only know about one, but I’m going to show you all of them. By the end, you’ll be able to create custom agents that act as your own specialized “sub-agents.” Getting Started: The Setup Before we dive into the agents, make...

How I Automate Jira Tickets Investigation using Claude Code & MCP

As a software engineer, I hate context switching. Investigating a Jira ticket usually means bouncing between Jira for the context, Confluence for the high-level logic, the Codebase for the actual implementation, and finally Slack to ping the reporter about blockers/additional questions. It takes time, breaks flow, and is incredibly tedious. So, I decided to automate the entire process using Claude...

From ChatGPT System Prompt to a Music App

Three technical decisions from productizing a pattern I'd been using by hand. For a while I'd been using ChatGPT as a music curator. Not a tool, not an app — a conversation. A system prompt describing the kind of listener I was and how I wanted to think about records. After listening to something I'd write a few sentences about how the record landed, paste them into the thread, and ask ...

How I used Python to turn a cheap 20$ smartwatch into a PC remote!

We’ve all seen them—those $20 Smartwatches on Amazon or AliExpress. They look decent, but they are locked behind sketchy, ad-filled mobile apps. I wanted to see if I could "liberate" the hardware. Today, I’m open-sourcing Synod: A Python-based engine that turns any generic BLE wearable into a dedicated macro deck for your PC. Why build this? Most smartwatches send "UI Notifications" over Bluet...

How Early-Stage SaaS Teams Build Scalable DevOps Without Overengineering

How Early-Stage SaaS Teams Build Scalable DevOps Without Overengineering

It’s a familiar trap for SaaS teams early on. They watch how companies like Netflix or Amazon build infrastructure, and try to copy them from day one. Good intentions, but the timing was off. Complex systems tend to require time, expertise and maintenance that small teams lack. The result is not faster progress, but slower delivery. Engineers spend more time managing infrastructure than develo...

Using CrewAI with Ruby Without the Boilerplate

The Ruby ecosystem has always been great for building clean, maintainable, production-ready systems. At the same time, tools like CrewAI are opening up a new world — multi-agent workflows that can research, generate, and collaborate on their own. Naturally, I wanted to try CrewAI from Ruby. But honestly… the experience wasn’t what I expected. ⚠️ The Gap Using CrewAI in Ruby usual...

Writing Code to Convert Quaternions to Z-Y-X Euler Angles in Python I needed to calculate Z-Y-X Euler angles from quaternions. Moreover, the task required me to write the code in Python 2.7, so I couldn't use handy tools like scipy.spatial.transform.Rotation. When I did some research, I found a sample code in C++ on Wikipedia. Wikipedia / Quaternion to Euler Angles Conversion ...

Claude Code on the Web: Why Your .env Vars Don't Reach the Setup Script (and How SessionStart Hook Fixes It)

TL;DR Environment variables you put in the .env panel of Claude Code on the web (Cloud Sandbox) do not reach the setup script. They only reach the shell inside the running Claude Code session. So git clone "https://x-access-token:${GH_TOKEN}@..." inside the setup script fails — GH_TOKEN is empty at that point. Move the clone into a SessionStart hook and it just works, because by then ...
