The AI Agents Roadmap Nobody Is Talking About (2026 Edition)

Introduction 😎 Spoiler alert 🚨 I should probably have called this "How to actually get hired building AI agents in 2026" considering I will be biased towards production systems in this article. Most tutorials teach you how to build a chatbot and then they just... stop. No deployment. No memory. No guardrails. Nothing about what happens when your "agent" hallucinates and tells a custom...

Modernizing the Facebook Groups Search to Unlock the Power of Community Knowledge

We’ve fundamentally transformed Facebook Groups Search to help people more reliably discover, sort through, and validate community content that’s most relevant to them. We’ve adopted a new hybrid retrieval architecture and implemented automated model-based evaluation to address the major friction points people experience when searching community content. Under this new framework, we’ve made tangib...

The FBI Got Hacked. Here's What That Actually Means

Chinese state-sponsored actors breached the FBI's surveillance coordination systems — not to steal data, but to see who the Bureau was watching. The "Major Incident" designation triggered a whole-of-government response, and the architectural lessons apply far beyond government networks.

Healthcare Risk Adjustment Tools from VBC Risk Analytics

Healthcare data engineering is hard. Healthcare risk adjustment data engineering is a category of hard that deserves its own word. If you've ever worked in health IT, you know the stack: EHR extracts that arrive in twelve different formats, ICD-10 codes that map to HCC categories under rules that change every model year, RAF scores that determine how much a health plan gets paid for every enrolle...

My AI Dev Team Doesn’t Sleep: Scaling a Self-Evolving Trading System to a 9% Weekly Return

It started as a classic "developer's trap": a side project meant to save time that ended up consuming every waking hour. I wanted a bot to execute trades so I wouldn't have to watch the charts. The logic was simple. The implementation, however, was a beast. Between scraping unstructured news feeds, managing low-latency data pipelines, and hunting edge-case bugs that only appeared at market open, ...

The Hidden Bottleneck in Web3 Apps: Event Consistency Isn’t What You Think

Why your dApp works perfectly… until it doesn’t. The Illusion of “It Works” A few months ago, I was reviewing a payment flow in a Web3 app. Clean architecture, solid contracts, decent frontend. On paper, everything was correct. User sends a transaction → smart contract emits event → backend listens → UI updates. Simple. Except… users were occasionally getting stuck in a “pending” st...

Build a No-Code AI Agent in 30 Minutes Using n8n + Claude (Full Walkthrough)

Monitor a Slack channel, summarise threads, post daily digests, all without writing a single line of code. I want to tell you about a Friday afternoon problem. Our team's main Slack channel had become unmanageable. Not because people were saying too much, because they were saying the right things at the wrong times. Someone would share a critical decision at 9am. Someone else would ask a questio...

I didn't set out to build a sustainability tool...

...but only seven weeks in, we've accidentally saved enough electricity to power roughly 65 American households for a year, and enough avoided CO₂ to take 64 gasoline cars off the road. I set out to fix a dumb problem: LLM coding agents load entire files into their context window to answer questions about single functions. That's expensive in dollars, it's slow, and it pollutes the context with j...

Migrating vector embeddings in production without downtime

In the fast-moving world of AI, models evolve rapidly. What was state-of-the-art six months ago is now being surpassed by newer models. For a RAG system, this presents a significant challenge: vector embeddings are tied to the specific model that generated them. If you want to upgrade your model, you can’t just start using the new one. Existing vectors in your database are incompatible with queri...

The AI Coding Comprehension Gap: Why Faster Isn't Always Better

AI coding agents have made developers dramatically faster. They've also made something else: a growing gap between the code that exists in a codebase and the code that developers actually understand. This post is about that gap — what causes it, why it matters, and what can actually be done about it. The Speed vs. Comprehension Tradeoff Here's a scenario that's become common: Dev...

No matter how I define the properties, they somehow get re-formatted to a completely different number. const y = Math.round(geom.centroid.y).toString() + "px" const x = Math.round(geom.centroid.x).toString() + "px" console.log("screen point = ", x, ...

Understanding Recursion in JavaScript — Explained in Simple Words

If you are learning DSA, recursion can feel scary at first. When I started learning it, I also felt like: “Why is a function calling itself?” “How do I know when it will stop?” “Why does this look so confusing?” But the truth is: Recursion is not hard because of the logic. It feels hard because we try to understand everything at once. So in this post, let’s not do that. Let’s understand rec...
