ShopEase: Advanced Backend Features with Webhooks, GraphQL, gRPC & Load Balancing

·1 views

In Modules 30.12–30.15, I worked on four advanced backend concepts: 💳 Payment Webhooks These modules helped me understand how real-world backend systems handle payment events, flexible data fetching, high-performance service communication, and distributed traffic. 💳 Module 30.12 — Payment Webhooks Payment processing doesn't end when a user completes a payment. A payment provider can send asynchronous updates about events such as payment success, failure, or other payment-status changes. For ShopEase, I implemented the payment webhook flow using Razorpay, including: Webhook endpoint One of th

Using Third-Party Models as Subagents Alongside Claude in Claude Code

Too few tokens, too many spare quotas I do most of my development on a Claude Code subscription. Right now Claude Fable 5.1 and Opus 5.5 work extremely well, and I would simply call them the state of the art. The only problem is that I keep running out of tokens.

Three AI judges, one dirty sink

How to turn an OpenAPI spec into an MCP server (2026 step-by-step)

Every team evaluating Model Context Protocol (MCP) servers reaches the same question: do we hand-maintain a second description of our API for agents, or do we generate it from the contract we already have? If you keep an OpenAPI document, the second answer is the sane one. An OpenAPI spec is almost literally a tool catalog already — each operation has a name, inputs, outputs, and a transport. Converting it to MCP is a mapping problem, not a modeling problem. This walkthrough covers what the mapping actually is, where generic converters fail on real specs, and how to verify the result with a re

Building Dice Atelier: a 3D dice roller with 20 themed tables, built by two AIs and one director

Two days ago our little free-tools site had a perfectly good dice roller. Then it got an upgrade with delusions of grandeur. Dice Atelier is a 3D dice roller for D&D night: twenty themed tables — an astral observatory, a clockwork library, a neon ronin bar — each with dice styled to match. Mixed pools, dice notation (try 4d6+2), advantage and disadvantage, up to 100 dice at once. It's free, no sign-up: https://penguinwearingahat.com/tools/dice-atelier/ No human wrote the app.
