PROJECT : LIVEL NAND flash software model development

The NAND flash model replicates the electronic behavior of storage devices on software platforms, implementing commands, functionalities, and specifications to assist ASIC and Firmware teams

Responsibilities:

• Software Model Development: Led engineering efforts to develop models for next-generation NAND (BiCS6 - BiCS10) and implemented new features per updated specifications
• Cross-functional Collaboration: Partnered with design, verification, ASIC, and firmware teams to gather requirements, timelines, and feature scopes
• ASIC and Firmware interface support: Developed System C interface for ASIC integration and APIs for firmware integration
• Feature Enhancement: Optimized existing features and addressed periodic specification updates while resolving customer-reported issues
• Mentorship: Guided junior teammates and interns to enhance team productivity
• Testing: Created new test cases to validate model features, ensuring robust performance and adherence to updated specs.

Initiatives:

• Code Optimizations: Re-architected modules for flexibility and configuration across NAND generations, enhancing performance and maintainability
• SSV Compiler: Developed a Python-based tool to automate SSV spec validation and test case generation, producing 50+ test cases with 25K+ lines per sheet
• Mode Compatibility Tool: Built a Python-based tool to analyze operation table specs and generate compatibility insights, expediting model updates for new specifications

PROJECT: Rich Communication Suite
The advanced communication suite with capabilities of 1-1 messaging, Group Chat, File Transfer etc

Responsibilities:

• Bug Fixes & Feature Enhancements: Resolved bugs and enhanced existing features for multiple customers, ensuring seamless functionality
• Test Automation: Continuously expanded the Jenkins-based test suite by adding new test cases for resolved issues and additional scenarios
• Collaborative Issue Resolution: Actively collaborated with the testing team to reproduce, analyze, and fix reported issues effectively

PROJECT: Google Home WiFi Router

Responsibilities:

• IPv6 Development: Designed and implemented IPv6 support, including a reachability state machine framework for stable connections and a health monitor for upstream connectivity
• Collaboration with Google: Worked closely with Google Inc to align roadmaps and deliver features on schedule
• Feature Enhancements: Enhanced networking capabilities such as port forwarding and station pause and developed anonymous and per-device metrics for new features
• Bug Resolution & CI/CD Maintenance: Addressed QA/customer-reported issues and resolved build errors in CI/CD pipelines and daily tests

PROJECT: M2M cellular based router with GPS

Responsibilities:

• Involved in Design, development and testing of middleware applications, LuCI web framework for a M2M platform running OpenWRT Barrier Breaker 14.07 OS which hosts Cinterion (PXS8/ALS3) LTE/GSM modem, uBlox receiver running on Freescale ARM9
• GPS server: Implemented GPS server to read data from device and upload it to server.
• CLI interface: Implemented a Command Line Interface (CLI) for executing commands, enhancing user interaction and control.
• LuCI Enhancements: Upgraded and extended the OpenWRT-provided LuCI interface, adding new pages for GPS and WAN applications.

PROJECT: Automation Test Framework development (for Wireless Charging of Devices)

Responsibilities:

• Automation framework development: Development of selenium-based automation test framework to automate Web UI, iOS and Android apps
• GUI development: Development of GUI interface to select and execute test cases and see live results.
• Log parser: Python utility to parse the log and validate the state machine from logs and assert any discrepancies found.
