Python SDK for AI Agents: Async Wallet Control with Zero Dependencies

Your AI agents can browse the web, write code, and manage files—but can they control a crypto wallet? Most AI agent frameworks stop at the edge of financial transactions, leaving a critical gap for agents that need to interact with DeFi protocols, pay for API calls with crypto, or manage digital ass...

The blocker was simpler: my account was created as a buyer, not a seller. Here's everything I learned about the Claw Mart creator setup, so yo...

Product Shipped! But Now What? The Part I Forgot About.

As a developer, I love to build. Planning it out, picking the stack, getting into flow state, watching something go from nothing to a working product. That part is fun. And with AI tools in the mix, that part is faster than ever. But here's what I've been facing in reality: shipping the code is...

AI Assistants — The Wiki-First Approach

In modern projects, the codebase grows exponentially, and AI assistants have become an integral part of the development workflow. However, without a single source of truth, every developer (and every AI agent) is forced to learn the project from scratch, wasting context window limits, time, and reso...

AI Voice Agent Pricing vs Human Receptionist: What 40+ Deployments Taught Me About True Cost

The advertised price is almost never what you pay. Vapi says $0.05 per minute. That is true if you ignore the LLM, the transcription engine, the voice synthesis, and the telephony carrier. Add those in and you are at $0.15 to $0.31 per minute before your first call ends. I have deployed AI voice ag...

My AI-Assisted workflow

You open a chat, describe what you want, iterate on the output, and ship something that more or less works. It feels fast. The features work, technically.

You Vibe-Coded. Now What?

I was at an AI event a few weeks ago when someone casually mentioned they'd vibe-coded their own CRM. Prompted into existence in a day to support their use-case. It sounded impressive in the moment.

Stop Coding Through Remote Desktop. Use VS Code Remote Tunnels Instead

I caught my AI agent posting a customer's SSN to Slack. Here's what I built to stop it.

Two months ago I was testing a support automation I'd built with CrewAI. The agent reads Jira tickets, pulls customer context, and posts a summary to the team Slack channel. Simple workflow. The kind of thing every second startup is building right now. It worked perfectly until a ticket came throug...
