Lambda, S3, AppSync, and CloudFront — engineering notes from running Hoomanely on AWS.
Modern backend systems rarely fail loudly. They fail quietly, through duplicated requests, partially completed workflows, retried executions, and replayed messages that look successful but slowly erode correctness. On AWS, these behaviors aren't edge cases or misconfigurations, they're the default operating conditions of a resilient, distributed platform.
How to build a clean, fast, and scalable asset workflow without a DevOps team. Introduction Whether you're building a Shopify storefront, a Flutter mobile app, a static website, or a serverless backend, one thing stays constant: your product lives or dies by the quality of its asset pipeline.
AWS migrations fail not because the technology is inadequate, but because the approach is wrong. Console-clicking through dozens of services, manually copying configurations, and hoping nothing breaks during cutover, this is how organisations rack up unexpected costs and endure hours of downtime. At Hoomanely we followed a better way: CLI-driven,
That ESP32-S3 prototype working perfectly on your desk? It'll brick itself in production. Here's the checklist that separates hobbyists from engineers shipping real products. You've built something magical. Your ESP32-S3 prototype streams 9-axis IMU data flawlessly. The BLE connects every time. Battery lasts for
