At Wideread, I started as a Frontend Developer, playing a key role in building a social media app for readers and writers from scratch using React Native. Later, I transitioned to Backend Development, taking full responsibility for managing our backend infrastructure with NestJS.I initially handled manual deployments on a VM and later migrated to AWS, implementing the entire infrastructure using Terraform with my team, along with managing our MongoDB Atlas database. Additionally, I automated critical processes, including building Docker images for the backend, generating mobile app artifacts, and deploying them via GitHub Actions.To enhance the app’s resilience and scalability, I introduced automated testing into our CI/CD pipeline, ensuring that code changes were thoroughly tested before deployment, leading to a more stable and scalable product.Throughout this journey, I worked closely with a dynamic team, operating within an Agile framework, and using Jira as our primary tool for task management and collaboration.
