As a senior NestJS developer at Copend, I build scalable and performant backend applications using MongoDB, Elasticsearch, and NestJS framework. I leverage my expertise in TypeScript, Node.js, and MERN stack to create robust and reliable solutions for various business needs and challenges. I also excel at DevOps practices and tools, such as Kubernetes, Docker, GitLab, Terraform, and Helm, to automate and streamline the deployment, testing, and monitoring of the applications. I optimize the data management and performance of MongoDB and Elasticsearch, using best practices and techniques. I lead and mentor junior developers, ensuring code quality, best practices, and continuous improvement. I am passionate about optimizing performance, solving problems, and delivering value to the clients and users.
