Project history
Developed large-scale web applications by maintaining RESTful *
* APIs and GraphQL endpoints; implemented a microservices
architecture using Node.js and Express.js.
Managed database design and optimization across SQL *
* (PostgreSQL, MySQL) and NoSQL (MongoDB) environments for
efficient data handling.
Integrated third-party services, including payment systems, into *
* the platform and led the creation of CI/CD pipelines with
Jenkins and Docker, reducing deployment times.
Reduced server response times through backend process *
* optimization.
