Multipart Update Infrastructure

• Created backend services to support multiple features as part of the redfish multipart update URI.
• Implemented backend DBus services for the features to populate the bundled firmware image in backend.
• Services to support the rollback & update of the firmware, separate threads running concurrently to handle the individual requests

Common Update Services

• As part of the software modularity to adapt the infrastructure to OpenBMC standards worked on this requirement to implement & port the existing update backend services to a common DBus infrastructure.
• Implemented multiple backend DBus services to provide features such as registration / de-registration / update / status to the update clients.
• Implemented services to support update orchestration for multiple devices e.g., Backplane, PSUs etc.
• Implemented ZeroMQ socket based IPC for inter thread/process communication.

Automating Server Health Predictions (Next Gen Autonomous Servers)

• Created module to predict server failures & self correct metrics to address underlying software/hardware issues in real time.
• Aimed to reduce server maintenance cost & provide customers with minimal downtime of servers.

Deploy & Configuration support for SMARTNIC devices

• Created multi-threaded module to provide support for importing/exporting attributes of smartNIC devices on server.
• Sub modules for inter-process communication b/w processes using DBus mechanism.
• Proper synchronization mechanisms using semaphores & file locks to avoid race condition between multiple threads/daemons.
• Sub-module to parse/generate user uploaded xml/json templates.

Responsibilities & Achievements

• SME for multiple modules , handling cross-teams customer impacting feature development & critical bug fixes.

• Got an early promotion to SSE role, one of the fastest promotions in entire org for my experience.
• Received numerous Dell Inspire awards & Game Changer for outstanding contribution.

POC for Dell server metric visualization & time-series analysis.

• Built end to end dashboard for Timeseries analysis and visualization of servers.
• Did Clustering analysis and Timeseries forecasting.
• Technology used: Python, Flask, Tensorflow, React JS.
