Karthik Shanmugam is a highly skilled Full-Stack Software Engineer with over five years of experience in web and mobile technologies. He specializes in designing and implementing high-performance API endpoints for large-scale transaction processing and building efficient data ingestion pipelines through database query optimization. Karthik has a strong background in building user-facing websites and mobile applications using JavaScript/TypeScript and NodeJS-based technologies. Karthik is highly passionate about computing at scale, performance optimization, parallel computing, and distributed systems. He is a strong believer in good design and a meticulous approach to writing software. Currently, he is pursuing a Masters in Computer Science at Binghamton University and is actively seeking Summer Internship opportunities. He is open to contributing and learning from every opportunity that comes his way. Karthik is currently working as a Software Engineer II at Aurigo Software Technologies, where he has built complex features for native apps across Android, iOS, and Windows platforms using Cordova. He has designed and established core sync APIs (REST) in .NET Core for large throughput traffic between mobile devices and the server. Karthik has also implemented critical security fixes on the Android app (Java) and got the application FedRAMP certified. He has published apps, updates, and fixes to the Google Play Store, and monitored crash reports, usage metrics, and analytics. In his previous roles at Epsilon, Karthik optimized existing API solutions for better performance via multi-threading and server-side caching. He designed tables and built data ingestion and transformation (ETL) pipelines in Oracle and wrote complex PL-SQL and tuning queries for large data volumes. Karthik also minimized query execution time for critical processes that took 6 hours to 20 minutes using PL-SQL parallel and bulk processing. He defined and implemented performance-critical APIs (C# .NET Core, Entity Framework, LINQ) for real-time payment transactions in online and point of sale systems, fine-tuned for speed at scale. Karthik holds a Bachelor of Engineering (B.E.) in Electrical, Electronics and Communications Engineering from PES University and is currently pursuing a Masters in Computer Science at Binghamton University. His TechStack includes Software Engineer, SQL, Mobile, Typescript, Android, Javascript, iOS, Frontend, Web, NodeJS, ETL, and Java. With relevant experience of 4.95 years, Karthik is actively seeking new opportunities to apply his skills and knowledge in Full-Stack Software
