Incorporate DevOps practices in day-to-day activities—CI/CD pipelines and automated testing—to improve operational efficiency and delivery quality.
Apply SDLC discipline, SOLID principles, and Clean Code practices; maintain high-quality technical documentation (designs/ADRs) and perform thorough code reviews.
Implement security best practices and design for scalability to ensure systems remain resilient as business needs evolve.
Implement unit and integration tests and collaborate with QA/QA Automation to expand test coverage and integrate automated tests into CI/CD.
Use Git effectively with established branching strategies (e.g., GitFlow or trunk-based) and actively participate in pull-request reviews.
