Led a cross-functional team of developers, designing and delivering scalable backend and frontend solutions. Built end-to-end systems using React, Vue, Svelte, .NET, Angular, and Node.js, with Ruby on Rails for certain services. Implemented RESTful APIs, integrated Stripe and Authorize.Net for payments, and enforced security with OAuth 2.0/JWT. Developed ETL processes for large data sets, modernized legacy monoliths to microservices, and improved CI/CD pipelines on Kubernetes. Created real-time data processing workflows with Kafka and DynamoDB Streams, and built robust test coverage (RSpec, Jest) while ensuring high availability across distributed environments. Containerized applications with Docker and deployed to AWS, Azure, and GCP environments, and contributed to architecture decisions to improve scalability and reliability.

Architected and developed SaaS e-commerce platforms, delivering end-to-end solutions across frontend and backend stacks. Implemented scalable services with React, Node.js, Ruby on Rails, and Go; leveraged PostgreSQL, MySQL, and MongoDB for data storage. Integrated payment gateways (Stripe, Authorize.Net) and designed RESTful APIs with strong security (OAuth2/JWT). Established Docker/Kubernetes-based deployments and CI/CD pipelines on AWS, with comprehensive testing using Jest and Cypress. Optimized performance, reduced latency, and improved system reliability for growing user bases.

Developed scalable web applications using React, Vue, and Node.js; implemented microservices architecture for e-commerce workflows; integrated Redis, PostgreSQL, MySQL, and MongoDB. Built secure payment flows and implemented continuous deployment pipelines. Collaborated with design and product teams to deliver user-centric features with a focus on performance and maintainability.
