Building a Video Downloader That Doesn't Break Every Time YouTube Sneezes

A few weeks back I wrote about the lessons I learned building 120+ free tools solo. A few people asked which tool was the hardest to actually keep working hands down, it's the video downloader. Not because the initial version was hard to build. Because YouTube (and every other platform) actively fights you, and the "happy path" breaks constantly in production. Here's what building and maintainin...

Part 6: When Your Angular Frontend and API Stop Agreeing

Part 6 of the Angular in Production series One of the biggest surprises I had working on larger Angular application is that many frontend bugs aren't actually frontend bugs. The component works. The service works. The HTTP request succeeds. Angular isn't throwing any errors. Yet something still feels broken. Maybe a table suddenly shows empty values. A form refuses to submit. A button disappears ...

How HTTP Responses Work in Dell Boomi? | Dell Boomi Interview question

The check was right. The key was wrong.

An agent gateway blocks a sequence: identity mutation followed by credential recovery. The rule is simple. If a session changes the contact email on an account, the same session cannot request credential recovery. The predicate is correct. Tests cover it. Receipts show the prior action list, the mutation event, the recovery attempt, and the block decision. During review the guard looks solid, bec...

Open-Source Multi-Agent Orchestration: Lessons from AgentForge

We built AgentForge to solve our own problem. Here's what 6 months of production multi-agent deployment taught us. Lesson 1: Start with Failure Modes, Not Success Cases Everyone designs for the happy path. But in multi-agent systems, the failure modes multiply: Agent A succeeds but takes 30s → Agent B times out waiting Agent A returns malformed JSON → Agent B crashes parsing Two agen...

SEO for Developers: Stop Over-Engineering Your Meta Tags

I spent three years thinking SEO was a magic black box. I thought as long as I had a sitemap.xml and some meta tags, the search engines would just figure it out. Then I built a project that had perfect lighthouse scores but zero traffic. That is when I realized that technical SEO is not about checking boxes. It is about how a crawler perceives your data structure. The Core Web Vitals Tra...

She is a 20-year-old third-year business student at Queen Mary University of London, articulate and qualified, and she has not received a single offer.

I audited 2,864 CI checks. Several had never run, and green never told me.

Someone on Hacker News asked a one-line question about the security checks I run on every PR: how often do those checks actually hold your PRs back? I didn't know. That bothered me more than it should have, so I counted every PR check I have ever run. 2,864 of them, across nine repos. The answer to his question turned out to be boring. What I found on the way to it did not. The boring ...

The Biggest Security Myth I Believed as a Beginner

AI will never replace tech workers because AI is not human

When we talk about AI these days, we're usually talking about large language models. To an LLM, the only reality it knows is data, and to be more specific, text data. Even when it looks at a photo, it's translating that photo into text data that it can understand through a vision encoder. But for humans, text is a small part of how we experience reality. Until the last few hundred years, text pla...

Building AIAnalyzer: A Swift Static Analysis Tool That Knows When to Trust Its Own AI

I've spent 18 years shipping iOS apps — enterprise VoIP, automotive, retail — and one problem kept resurfacing regardless of the domain: codebases quietly rot, and Swift never had great tooling to catch it early. Most static analysis tools are style linters, not architecture watchdogs. Nothing was really looking for God Objects, tangled responsibilities, or classes that had silently outgrown their...
