Build a Shopify App with Python

This technical tutorial explains how to build a Shopify app using Python and a lightweight web framework (Flask). It covers environment setup (Python 3.9+, Flask, shopify package, ngrok), creating an app in the Shopify Partner Dashboard, implementing OAuth and webhook endpoints with example Flask code, fetching products via the Shopify API, testing on a development store, and deployment options (Heroku, AWS, DigitalOcean, Render; frontend on Vercel or Netlify). The guide demonstrates practical code snippets for install/finalize OAuth flows, product retrieval, and an orders/create webhook handler.

Developer Builds AI Alt-Text Generator for WordPress

A developer built an AI-powered alt-text generator for WordPress to automate descriptive image alt text generation and reduce manual workload. The project evolved into a production-ready plugin with a stack including WordPress/PHP, JavaScript, Node.js, Render, Supabase, Stripe, and PostHog, plus an external AI vision service. Key engineering lessons cover clear telemetry semantics (job-level vs item-level events), deduplication strategies using stable PostHog insert IDs and event ownership, correlation IDs for cross-system tracing, privacy-by-default telemetry (strip PII and content), and controlled internal error taxonomies. The article emphasizes that reliability (authentication, billing, idempotent webhooks, privacy-safe analytics, observability) matters as much as the AI feature itself.

Personal Website: Tech Stack, Architecture, Lessons

A software engineer documents building their personal site (shubhkumar.in) with a decoupled frontend and backend, focusing on performance, reusability and separation of concerns. The frontend uses Next.js and Tailwind CSS and is hosted on Vercel; the backend is an Express.js API (api.shubhkumar.in) running on Render. Data is stored in MongoDB Atlas with a cloud-managed Redis cache in front to reduce latency. The architecture uses a two-tier aggressive caching model (Redis at the API tier and Next.js time-based revalidation at the frontend) and leverages Vercel’s edge network for fast global responses. The author describes operational fixes for cache synchronization (planned webhook pipeline to DEL Redis keys and call Next.js revalidation APIs), simplifying an over-engineered backend, and mitigating cold-start latency via connection-pooling and heartbeat pings.
