With more than 8 years of experience in web and mobile app development, I specialize in JavaScript, particularly in MERN/MEAN stacks, Android development, and browser extensions (v3) using React. Additionally, I have secondary expertise in Java, SQL, Google APIs, TypeScript, and Kotlin.My domain knowledge spans across E-commerce, Fintech, Pub-Sub modules, Real-time Streaming, DAP, SAAS, and PAAS. In system design, I excel in creating highly optimized solutions, with a focus on authentication, session management, security, minimum latency, and scalability. I ensure seamless deployments while avoiding bottlenecks, leveraging services such as Redis, Kafka, MSGraph, Elasticsearch, and Camunda, along with Real-time Databases. I also employ AWS along with Nginx, PM2 for deployment strategies using EC2, S3, Lambda, and implement CI/CD pipelines using Jenkins to ensure code is linted, unit tested, and properly built before pushing to higher environments.As a team lead managing a team of about 4 members, I take responsibility for various tasks. This includes managing tasks, providing estimates, conducting pre-deployment demos, and interacting with the QA team to ensure that features and issues are completed by validating test cases, as well as passing sanity and regression tests. Additionally, I provide technical support and guidance to the team to ensure that the code meets standard protocols and adheres to proper code formatting. Moreover, I ensure seamless deployments without downtime. My role involves overseeing the entire development process and ensuring that our team delivers high-quality, reliable software solutions.Furthermore, I have experience in React Native for cross-platform mobile app development and some exposure to game design using Unity.
