AI Resume Builder: How to Ship Better CVs Faster

Hiring teams skim. ATS filters. And most resumes still read like everyone copy-pasted the same “results-driven” template. An ai resume builder can fix that—if you use it like a tool, not a slot machine that spits out buzzwords. In this post, I’ll show a practical, technical workflow for using AI to produce a resume that’s scannable, specific, and ATS-friendly, without turning your experience into...

Why I Replaced lsof with a Rust-Based "Sniper" Button

Every developer has a "favorite" annoying workflow. Mine was hunting down zombie processes that refused to release my local dev ports. If you've ever typed this into your terminal for the 5th time in an hour, you know the pain: lsof -i :3000 kill -9 <PID> I decided to automate this friction away by building Recoil—a tactical system monitor for macOS that lets you "snipe" these proc...

Designing Scalable Product Catalog APIs With Cassandra, GraphQL, and AI

This article breaks down how to design a retail system that actually works at scale using Cassandra, GraphQL, and AI. The key is not the tools themselves, but how you use them together: * Precompute as much as possible to avoid slow requests * Design for traffic spikes, not average load * Keep Cassandra queries predictable and optimized * Let AI handle decisions, and Cassandra handle fast retrie...

🛡️ Lirix v1.4.1: The Ecosystem Domination Release

Stop letting your AI agents raw-dog the blockchain. In Web3, a hallucination is not a harmless bug. It is a transaction request away from becoming a financial incident. If you are building AI agents with LangChain, AutoGen, or a custom orchestration stack, and you are letting them reason anywhere near private keys, swaps, approvals, bridges, or DeFi execution paths, you already know the trut...

I Let OpenClaw Run My Mornings for 7 Days. It Stopped Acting Like a Chatbot on Day 4.

This is a submission for the OpenClaw Writing Challenge For three days I almost uninstalled OpenClaw. I had connected it to Telegram, GitHub, and Google Calendar, and every morning at 8 AM it sent me the most useless message I have ever received from a piece of software: "You have 4 open PRs. Consider reviewing them." Thanks. I have eyes. The breakthrough came on day 4, and it had nothing to do ...

Master-Class: Sending Real-Time Updates from Server to Clients: Server to Server, Android, iOS

Real-time communication is now a cornerstone of modern software. Whether you're showing live scores, streaming AI responses, pushing a payment confirmation to a phone, or propagating an event between two microservices — the underlying question is the same: how does the server reach the client before the client asks? The answer looks very different depending on who the client is. A backend server,...

I Document Like a Professional at Work. My Side Projects Are a Disaster.

It feels like documentation at work is more of a checking the box exercise sometimes. My own side development projects brought a lot to light. I write business requirements documents. I write functional specs. I write process flows, configuration workbooks, user guides, and the occasional runbook that lives on a shared drive forever. None of it because I love writing documentation. I do it becaus...

Quand plusieurs producteurs proposent des blocs, le réseau doit s’accorder sur quel bloc ajouter maintenant. C’est ce qu’on appelle le consensus : c’est un protocole qui permet à tous les nœuds d’être d’accord sans chef. Preuve de travail (PoW) : le bloc du mineur le plus rapide (et valide) est choisi. Preuve d’enjeu (PoS) : le bloc du validateur sélectionné est choisi, et d’autres validateurs ...
