An infographic-style blog cover image titled "SST Era vs. Claude Code Era," illustrating a software migration. The left side, labeled **"SST Era,"** has a dark blue background showing a chaotic, tangled web of icons including AWS Lambda, Docker, SQS, and TypeScript (TS) logos, accompanied by red warning arrows and text like "Infrastructure Pain" and "Zero commits for 5 months." A large central arrow labeled **"MIGRATION"** points to the right side, labeled **"Claude Code Era."** This side has a clean, light teal background featuring organized icons for FastAPI, Python, Celery, and a friendly AI robot mascot. Stats in the center highlight the scale of the change: "432 Files Changed, 24,422 Insertions, 11,569 Deletions." The overall composition depicts a transition from serverless complexity to a streamlined, AI-assisted monolith architecture.

I Used Claude Code to Migrate My Full-Stack App from Serverless to Monolith

A vibrant digital illustration depicting the "Phoenix Pattern" in Flutter for app restarts. At the center is a fiery, mythical phoenix with wings spread in shades of orange and teal, symbolizing rebirth. The image shows a visual loop: on the left, an existing mobile app interface (labeled "LOGOUT" and "STATE") is breaking down into pixels and particles. A curved orange arrow leads upwards from this old state through the phoenix, representing transformation. A second arrow leads from the phoenix down to a fresh, identical app interface on the right (labeled "NEW" and "STATE"), symbolizing the clean, restarted state. Various Flutter-specific technical labels are integrated into the design: * The Flutter logo (a blue 'F') is present in the background. * Text snippets like "StatefulWidget," "UniqueKey," "KeyedSubtree," and a code structure snippet "widget_tree" emphasize the framework's mechanics. * The overall composition illustrates the conceptual flow of destroying the widget tree and rebuilding it immediately with a new key.

A German-language digital illustration shows a thoughtful man sitting at a desk with a laptop, pondering payment terms for freelancers. A question mark floats beside his head, and the text above reads: "7, 14 oder 30 Tage – was ist fair?" The background features minimalist office decor, including a plant and a framed graph.
