Naryanam Kundhan

• Architected and maintained scalable REST APIs using Python (FastAPI/Flask), handling thousands of daily requests, with 99.99% uptime.
• Implemented advanced caching strategies (using Dragonfly), reducing average API response times by over 60%.
• Automated complex data workflows and routine backend operations, improving team efficiency and reducing manual intervention time by over 30%.
• Introduced background job processing and asynchronous task queues (e.g., with threading), enabling seamless handling of time-consuming processes, like image processing and file uploads.
• Enhanced data integrity and reliability by building validation layers, automated testing pipelines, and robust error handling, resulting in a 25% drop in production incidents.
• Leveraged AI and LLMs to develop a Playwright-based automated testing suite, enabling rapid regression checks and data-driven insights. This empowered the team to confidently restructure critical parts of the application, accelerating delivery cycles, and reducing risk.

worked on open source data query and manipulation language(GraphQL) across multiple web application APIs, which replaces the usual REST implementation of web applications.

• This greatly reduced the data under fetching problem and combined multiple API calls.
• implemented microservice architecture to multiple APIs using apollo graph ql
• Worked with software development and testing team members to design and develop robust solutions to meet requirements for functionality, scalability and performance.
• Managed multiple concurrent projects while maintaining strict adherence to deadlines and budget constraints.

• Design and develop ETL integration patterns for business intelligence using pyspark.
• Optimized existing pyspark code base using cache management which reduced execution time by 10%.
• Developed interactive jupyter notebooks for defect management which reduced turnaround time by 55% for resolution.
• Involved in POC for automating daily report generation of data in hive tables.
• Experience in hive SQl queries and spark jobs.
• Experience in delivering high complex project in Agile methodology.

• Worked on complete lifecycle, design, development, testing on OOA and OOD
• Build Java applications using Maven and deployed it in tomcat and websphere application servers.
• Maintained complex technology infrastructure and collaborated with product team to implement new features and strategically plan for future products.
• Participated in requirements gathering and design development meetings.
• Researched new package releases periodically and updated them in web application.
