Architected and developed a microservices-based backend infrastructure using Node.js (Express.js, Nest.js),enhancing scalability and modularity of the application’s core services.Designed RESTful and GraphQL APIs to streamline communication between services and improve data access efficiency, achieving a 30% reduction in API response times.Managed deployments across AWS and Google Cloud Platform, leveraging Docker for containerization and Kubernetes for orchestration, enabling auto-scaling capabilities to handle peak loads seamlessly.Built CI/CD pipelines using Jenkins and GitLab CI, automating testing and deployment processes, which reduced deployment time by 50% and increased release frequency.Implemented Infrastructure as Code (IaC) with Terraform and Ansible, automating infrastructure provisioning and configuration management, achieving consistent environments across development, staging, and production.Enhanced application security by integrating AWS IAM roles, setting up role-based access control, and implementing API gateway rate limiting, reducing vulnerability incidents by 40%.Established robust monitoring and logging with Prometheus and Grafana for real-time alerts, as well as centralized logging through the ELK stack, resulting in faster incident detection and resolution.Technologies Used: Node.js, Express.js, Nest.js, RESTful APIs, GraphQL, Docker, Kubernetes, AWS, Google Cloud Platform, Jenkins, GitLab CI, Terraform, Ansible, Prometheus, Grafana, ELK Stack

Spearheaded the migration of a monolithic application to a microservices architecture on AWS, using Node.js and Express.js for each service. This transformation led to a 40% reduction in system downtime and improved fault tolerance.Developed automated CI/CD pipelines with Jenkins and Terraform, enabling rapid, repeatable, and reliable deployments across multiple environments.Optimized the backend infrastructure by implementing Redis as a caching layer, decreasing latency in API responses by 25% and enhancing the user experience.Designed and implemented a serverless architecture for specific backend services using AWS Lambda and API Gateway, reducing operational costs by 30%.Enhanced data persistence and availability by managing PostgreSQL and MongoDB databases, implementing backup strategies, and fine-tuning queries for better performance.Integrated monitoring and alerting systems using Prometheus and Grafana, and centralized logging with ELK Stack to improve visibility into system health and proactively address performance issues.

Developed and maintained responsive and interactive user interfaces with React.js, delivering seamless user experiences for client-facing applications.Designed and implemented high-performance backend APIs with Node.js and Express.js, ensuring efficient data handling and reduced latency.Optimized database schemas and queries in PostgreSQL and MongoDB, achieving a 20% improvement in query response times and overall database performance.Built containerized applications with Docker, standardizing deployment processes across development, staging, and production environments.Implemented and maintained CI/CD pipelines with GitLab CI, automating build, test, and deployment workflows, reducing manual intervention and deployment times by 40%.Configured server-side load balancing and failover setups, ensuring high availability and consistent performance under varying loads.Collaborated with frontend, backend, and mobile teams to deliver cohesive solutions, resolve technical challenges, and ensure efficient project delivery through active code reviews and communication.
