•Spearheaded the successful launch of a microservice-based SaaS Platform, developing a comprehensive launch strategy
•Introduced DDD(Domain Driven Design) principles to model complex business domains, resulting in a significant reduction in code complexity and improved maintainability
•Implemented Event-Driven Architecture with AWS EC2, SNS, and SQS, improving system scalability and responsiveness
•Migrated PHP monolithic application to microservice-based architecture with Node.js, gRPC, and PostgreSQL, resulting in improved system reliability and scalability
•Conducted indexing and caching techniques to optimize database operations and reduce server load, resulting in a more responsive and reliable system
•Improved the scalability and resilience of data pipeline migrating from Microsoft SQL Server to AWS Snowflake and implementing Redis and Amazon EFS
•Integrated the chatbot with backend systems to streamline customer interactions and improve their response time with detailed guidance
•Led the development of large-scale SPA(single-page application), leveraging React and Redux-Saga to deliver efficient and scalable solutions
•Optimized the website performance increasingly by implementing SSR(Server Side Rendering) with Next.js, lazy loading, code splitting, and caching mechanism
•Leveraged A/B testing using Split, to provide a better user experience with an 8% improved conversion rate
•Designed and implemented a comprehensive testing strategy using Jest and Playwright and planted testing part in front of the automated CI/CD pipeline with Docker and Kubernetes to automate testing and reduce the deployment time
•Established the appropriate Agile development process using Scrum methodology, which improved communication and collaboration
•Conducted the code review 100+ times and mentored junior developers during their onboarding process…•Spearheaded the successful launch of a microservice-based SaaS Platform, developing a comprehensive launch strategy
