Modern agents like Claude Code, Codex, Cursor and OpenCode need skills, hooks and MCPs, but they load them differently. I made a tool that creates an ephemeral staging configuration that loads into coding agents without polluting the global user or project configuration. GitHub Link Loading terminal recording... I’ve been using AI agents for building commercial software—it’s incredibly…
In the last 6 months, I’ve helped 3 AI startups migrate from Vercel or Cloudflare to AWS Lambda . The pattern is the same: they start on a platform with great DX. Then the wall shows up: background jobs, retries, queues, cron, and eventually a “this endpoint needs 2-8 GB RAM for 4-10 minutes” workload — and they land on AWS. To be fair: Vercel and Cloudflare captured developer…
In 2025, playing your own music on an iPhone is surprisingly hard , unless you pay Apple or navigate a maze of limitations.

In a startup, your survival depends on how quickly you can iterate, ship features, and deliver value to end-users . This is where the foundational architecture of your startup plays a big role; additionally, things like your tech stack and choice of programming language directly affect your…
TL;DR: I built a lightweight, self-hosted HTTP tunnel that turns localhost into a public HTTPS URL. No paid plans, no secret black boxes. Just one Go binary, Caddy with wildcard TLS, and a $0/month Oracle Cloud VM. GitHub repo Why I Built It My development workflow lives mostly on a free Oracle Cloud VM: SSH, Neovim, tmux—the usual hacker starter pack. I tried many ways to easily expose my local…
As a web developer, having access to a persistent, virtual machine in the cloud is often useful for testing and development. While many cloud-based providers offer limited free tiers (e.g. AWS, GCP, or Azure), Oracle Cloud stands out by providing a true “always free” cloud VM. In this article, we’ll look into setting up Oracle VM (under their always free tier). There are multiple…

This article walks through how I set up my technical blog, aimed at those new to blogging or Hugo. Choosing the platform For me, it’s important to have as minimal a solution as possible. While building my own Markdown-to-HTML publishing…
