His primary technical home base is Python and Django, and he works as a full-stack engineer with Python-based APIs, data-driven services, React and TypeScript interfaces, PostgreSQL, Docker, testing, SQL optimization, and CI/CD. At Sentry, Arjun has extended AI-assisted issue triage across Django services and React interfaces, integrating LLM-generated issue summaries into debugging workflows while preserving permissions, error handling, trace context, and fallback behavior. That work reduced manual investigation effort by 18% and included validation across 500 representative production incidents. Previously at CGI, he built an authenticated operations workflow application with FastAPI, React, PostgreSQL, AWS services, OAuth 2.0, JWT access controls, Docker, PyTest, and GitHub Actions incremental releases reduced average application turnaround from five business days to three. At TCS, Arjun developed Python modules and responsive portal interfaces, automated recurring data checks that saved four hours weekly, and supported structured API and database testing. He holds a Master of Science in Computer Software Engineering from Arizona State University and a Bachelor of Technology from PES University. ## Services - WebSocket - REST APIs - FastAPI - Microservices -
