Lessons learned as a software engineer: 1. Automate everything that benefits from automation using tools like Jest, Slack bots, Selenium, Protractor, ESLint, Terraform, and Applitools. 2. Use linting rules to enforce best practices and code quality. 3. Conduct code reviews which are a good way to improve coding skills.
