We Ditched Terraform 1.10 for CloudFormation: Reducing IaC Complexity for Our Small AWS Team We’re a 4-person engineering team managing 32 AWS resources across dev, staging, and production environments for a B2B SaaS product. For 18 months, we relied on Terraform 1.10 to manage our infrastructure as code (IaC). But by Q3 2024, the overhead of maintaining Terraform outweighed its benefits for our

A problem asks for the longest substring with at most K distinct characters. You've solved sliding window before. Maximum sum subarray of size K, done. Longest substring without repeating characters, done. This third one stalls you. Twe

Two years ago, I was three semesters into a traditional Computer Science degree, drowning in abstract calculus and outdated Java curriculum, wondering if I’d ever write code that actually mattered. Today, I’m a backend engineer working full-time with Go 1.25, building low-latency m
Opinion: We Ditched All Third-Party Mobile SDKs – Cut App Startup Time by 30% for iOS 18 When iOS 18 launched, our team braced for the usual post-release performance tweaks. Instead, we hit a wall: our flagship app’s cold startup time had crept up to 2.8 seconds, well above Apple’s recommended 1.5-second threshold for optimal user retention. After months of debugging, we made a radical call: rem
