Rewriting the same solutions over and over is the enemy of productivity. Building a personal library of patterns and reusable modules radically changes your development pace.
Every experienced developer has lived this moment: solving a complex problem on one project, documenting it carefully... then solving it again six months later on another project from scratch. Code capitalization is the art of avoiding this waste. Not by creating an over-engineered universal library, but by progressively building a collection of proven solutions.
The first step is identification. What problems do you solve regularly? JWT authentication, pagination, error handling, date formatting helpers — these are obvious candidates. Create a private monorepo or a simple folder of snippets organized by domain. The format doesn't matter — what matters is the discipline of capture: when you solve something interesting, take ten minutes to extract and document it.
The second level is the company's internal library — a shared repository across all projects, managed like a real package with versioning. Architecture patterns (Spring Boot configuration, Angular project structure, CI/CD pipelines) lend themselves particularly well to this exercise. Gotan maintains a set of starter kits that reduce new project bootstrap time by 60%. Productivity doesn't come from typing faster — it comes from not typing twice.
