Experience
Oracle OCI July 2023 – Current
Member Technical Staff Bengaluru, Karnataka
• Worked in the Compute organization, focusing on host provisioning and managing repair services for bare metal servers.
• Automated an end-to-end decommissioning process for high-performance MLIO servers, replacing manual effort and
eliminating the need for one manual resource.
• Owned and enhanced a script to automate change management ticket creation, cutting ticket processing time by
50% and streamlining approvals and deployment process.
• Orchestrated migration of Jira Service Desk to an in-house ticketing system, streamlining transition for the team
• Developed an Oracle Cloud Analytics (OAC) dashboard for executive management to analyze operations
metrics weekly, monthly, and quarterly, utilizing OCI Jira data, and extensively used in operations review meetings.
Oracle OCI June 2022 – July 2022
Software Developer Intern Bengaluru, Karnataka
• Developed RESTful API routes for a Triage tool to efficiently manage and triage large fleet of Bare Metal servers.
• Implemented threading to enable the parallel processing of multiple Bare Metal servers, greatly improving efficiency by
allowing concurrent triage instead of sequential execution.
• Enhanced ticket resolution for SREs, effectively reducing the number of servers in the REPAIR queue by an average of
30% per month through the triage tool.
• Utilized Python Flask for API development, Oracle Cloud Console for managing cloud resources, and Bitbucket for
version control and collaboration.

Projects
Improvements in Wireless sensor Networks using sense-sleep trees | C++, NS2
• Contributed to a research paper implementation to improve wireless sensor network efficiency using sense-sleep Trees.
• Implemented Dijkstra’s Algorithm to calculate the shortest paths and determine optimal node placements within the
Sense-Sleep Tree framework.
• Designed and tested optimization strategies to minimize shared nodes in the Sense-Sleep Tree, improving network
performance metrics such as packet loss and extended network lifetime.
Leetcode Code Execution Platform | JavaScript, TypeScript, MongoDB, Redis, Socket
• Engineered a Problem Admin Service using JavaScript, Express, and MongoDB for managing CRUD operations,
including complex test cases and code stubs to facilitate comprehensive evaluation.
• Developed an Executor Service using Docker containers to support multi-language code execution (Java, Python,
C++). Applied Strategy and Factory design patterns to optimize execution environments and handle Time Limit
Exceeded (TLE) conditions effectively.
• Designed a Submission Service with Fastify, managing a high volume of requests efficiently. Utilized Redis message
queues for efficient asynchronous communication, ensuring integration between submission and executor services.
• Implemented WebSocket services to deliver real-time feedback to users, enhancing interactivity and responsiveness.
