Every piece of software is built to meet required specifications. It can be computation time/cost, performance, request per second or storage. In some case request per second is more important than cost or viceversa.
Security is one of our first aim when building something. From API Keys to sensitive data every data is encrypted or hashed as needed and stored only in secure environments.
Every function is commented. A documentation is then generated to accompany the code. Unit tests and integration tests are used for CI/CD pipelines and issue coverage reports.
