Flutter Payment Gateway Comparison: What Actually Works in India

I've integrated six gateways into Flutter apps for clients over the last few years. Here is the honest scorecard — fees, UPI support, mandates, settlement, and the gotchas the marketing pages skip. Choosing a payment gateway for a Flutter app in India is not a coding problem. The Flutter side is nearly identical across gateways — a SDK call, a result callback, a webhook your server verifies. The ...

The Full Stack: Specs + Skills + Stewardship in a Single System

Building the AI Dark Factory — Issue #19 Preface I want to be upfront about something before we get into it. None of the frameworks in this article is mine. The ideas here come from two people who have been thinking about this stuff way harder and longer than I have — and they deserve full credit before I say another word. Dan Shapiro — CEO of Glowforge, Wharton Research Fellow, and t...

Strands on AgentCore, Answering Two Other Clouds: The Contract, the Header, and the microVM

Strands ships no A2A server integration, which turns out to be the easiest starting position of the three frameworks I used: you drop the agent behind the a2a-sdk reference routes and you are serving the protocol's own implementation. The hard part was never Strands. It was AgentCore Runtime — a container contract that is narrow, mostly undocumented in one place, and different from every other ru...

ADK Beyond Its Own Tests: What Happens When Your Agent Answers a Client That Is Not ADK

to_a2a() turns an ADK agent into an A2A server in one line. That is genuinely the shortest path from an LlmAgent to something another vendor's agent can call, and it is the reason I started here. Then I put that agent in a mesh where the callers are not ADK — a Strands agent on Bedrock AgentCore and a Microsoft Agent Framework agent on Azure Container Apps, all three given the same research brief...

Introduction A chatbot is a software application that allows users to interact with a website or application through a conversation-based interface. Today, chatbots are widely used by companies to provide quick support, answer common questions, guide users, and improve the overall user experience.

Introducing Quero

AI tools are everywhere now. There are chatbots for writing, coding, research, brainstorming, searching, summarizing, planning, and apparently every other activity humans have decided should involve a text box. But I wanted something simpler. Quero is a quiet AI workspace for thinking, creating, and getting things done. What is Quero? Quero is an AI assistant designed around a simple idea...

DEPENDENCY INVERSION PRINCIPLE

High-level modules should not depend on low-level modules. Both should depend on abstractions (interfaces). In practice, your business rule shouldn't know if you use MySQL, Stripe, or AWS. It should depend only on a contract (Interface) that says WHAT needs to be done, and not HOW it will be done. RIGID IMPLEMENTATION The most common mistake on a daily basis is calling a new Extern...

The AI-Augmented Developer: A Practical Guide to Refactoring and TDD with Cursor

The narrative that "AI is going to replace full-stack engineers" has matured. In real-world software engineering, AI isn't replacing developers. Instead, it is increasingly replacing the tedious, repetitive, and mechanical parts of development. We are firmly entering the era of AI-Augmented Development. For full-stack JavaScript and MERN developers, the biggest bottleneck is rarely typing synta...

Módulos de alto nível não devem depender de módulos de baixo nível. Ambos devem depender de abstrações (interfaces). Na prática, a sua regra de negócio não deve saber se você usa MySQL, Stripe ou AWS. Ela deve depender apenas de um contrato (Interface) que diz O QUE precisa ser feito, e não COMO será feito.
