Led architecture, design, and development of scalable web applications using Angular, React, Java (Spring Boot), and Python frameworks. Developed SPAs with React including state management using Redux Toolkit and performance optimizations. Built microservices in Node.js and deployed using Docker and Kubernetes on GCP. Implemented RESTful and GraphQL APIs, serverless microservices using AWS Lambda and API Gateway, and integrated asynchronous workflows with SQS and SNS. Designed and optimized SQL and NoSQL schemas and implemented testing with Jest and Postman. Automated CI/CD pipelines using Jenkins and GitHub Actions, and created stakeholder dashboards and technical documentation.

Led design and implementation of microservices-based payment processing systems using Node.js and containerized deployments with Docker and Kubernetes on AWS ECS. Architected Angular dashboards with real-time data visualization using D3.js and Chart.js. Developed high-throughput, secure RESTful API gateways integrating MySQL and MongoDB. Delivered performance optimization and CI/CD pipelines with GitHub Actions and Kubernetes, enabling zero-downtime deployments. Migrated monolith systems to microservices with documented API contracts and telemetry monitoring via Prometheus and Grafana. Collaborated with data science teams to productionize AI/ML models for predictive transaction risk scoring, improving fraud detection capabilities. Enforced secure coding practices and mentored teams on TypeScript best practices.

Implemented Identity and Access Management (IAM) and encryption to secure DynamoDB and SQL Server data. Performed unit testing with Jest and React Testing Library, maintained responsive UIs following accessibility standards, and migrated legacy React components. Developed server-side rendering with Node.js and Next.js. Integrated OAuth2, Stripe, and Twilio APIs and built real-time apps using Socket.io. Applied domain-driven design principles to build scalable microservices using Spring Data JPA and Spring Scheduler. Managed Jenkins and GitHub Actions CI/CD pipelines, Kubernetes deployments, and performed API load testing with JMeter. Used AWS services including Lambda, S3, DynamoDB with caching and monitoring tools, and implemented disaster recovery strategies.
