Design and build scalable microservices using Node.js, Express.js, Golang, and Python to support enterprise networking applications and cloud platforms. Develop frontend applications with React and Angular, implement RESTful and GraphQL APIs, containerize services with Docker, and orchestrate deployments with Kubernetes. Implement OAuth2 and JWT-based authentication, build real-time data processing services in Golang, and develop automated testing frameworks with Jest and Cypress. Deploy multiple web applications and collaborate with product, design, and engineering teams to deliver scalable, secure software. Establish monitoring and observability using Prometheus and Grafana to improve system visibility and issue resolution.

Took ownership of designing and building scalable microservices in Node.js/Express; built React front-end components; introduced GraphQL APIs to reduce over-fetching; containerized apps with Docker and orchestrated with Kubernetes; implemented OAuth 2.0 and JWT authentication; set up automated testing with Jest and Cypress; explored Golang microservices and Rust services to enhance performance; contributed to the delivery of multiple internal and client-facing applications.

Led design and development of scalable microservices using Node.js/Express. Built React front-end components with hooks and Context API for reusable code and improved developer experience. Introduced GraphQL APIs to reduce over-fetching and speed data retrieval, improving page load times. Standardized deployments by containerizing apps with Docker and orchestrating with Kubernetes, reducing environment-specific issues. Implemented OAuth 2.0 and JWT authentication to strengthen security while keeping login flows user-friendly. Set up automated testing with Jest and Cypress. Explored Golang microservices for high-concurrency workloads and built a Rust-based data-streaming service for secure, memory-safe processing. Contributed to the delivery of numerous applications used internally and by clients, boosting adoption and satisfaction.
