Work History
Senior Software Engineer
Microsoft
Hyderabad
09.2024 - Current
- Strengthened malicious extension detection and automation: Designed and implemented edge browser client-side and backend pipeline enhancements to collect and analyze extension data, enabling automated alerts and early detection of threats. Initial rollout flagged dozens of malicious extensions and uncovered large-scale side-loaded installs, leading to proposed disablement strategies that protected over 1.7M users.
- Advanced security infrastructure and detection accuracy: Improved core scanning systems by optimizing partitioning, telemetry, and feedback loops, resulting in measurable gains in detection accuracy (69% → 72%) and precision (96% → 100%). Drove security compliance initiatives with zero SLA breaches and introduced workflow automation that reduced manual effort by ~50%.
- Enabled team success and knowledge sharing: Onboarded peers to new security dynamic analysis simulations, created reusable workflow artifacts, and supported deprecation of legacy services. Led knowledge-sharing sessions, promoted inclusive collaboration, and streamlined backlog prioritization—improving team efficiency, culture, and alignment with organizational security and D&I goals.

09.2022 - 08.2024
- Optimized Azure costs and infrastructure efficiency: Consolidated app service plans and removed unused resources, achieving a 23% reduction in Azure COGS and lowering CO₂ emissions, as recognized by the Azure team.
- Strengthened security platforms and tooling: Drove ADF pipeline deprecation analysis and migration to Redash for security use cases, resolved 376+ component governance alerts (including critical OSS vulnerabilities), enabled data sharing for ML badge models, and integrated the Process Investigator tool into DA simulations.
- Designed and implemented EVAL & RAI scanners for AI plugins, integrating with Sydney and Azure Promptflow pipelines to provide multi-turn evaluation metrics (content harm, copyright/IP, DEA, trigger rates, irrelevant queries, etc.).
- Enhanced reporting and telemetry by driving requirements for new metrics (e.g., top wins/losses, Sydney searches), integrating EVAL/RAI outputs into TSR and URS, and enabling report downloads with full evaluation dumps for researchers.
- Developed scalable and maintainable code, ensuring long-term stability of the software.
Software Engineer 2
Microsoft
Hyderabad
09.2021 - 08.2022
- Laid the foundation for edge browser extensions security service infrastructure by setting up logging, telemetry, and monitoring frameworks integrated with Azure App Insights and Kusto. This enabled proactive ICM resolution, Power BI dashboards for security insights, and standardized observability across services.
- Drove the design and development of the Dynamic Analysis (DaaS) system, including SONAR VM configuration, toolset integration, activity log generation, and callback handling. DaaS became a critical addition to the extensions security arsenal—flagging malicious extensions missed by static tools, leading to 7 revocations, and delivering measurable precision/recall benchmarks. Extended DaaS with UI simulation and network logging, raising detection accuracy to ~67% F1 score, and established it as a scalable platform for future features.
- Accelerated team and cross-org success by completing privacy reviews, onboarding reviewers and partner teams to DaaS, and contributing to ML-based security research. The ML prototype leveraging DaaS and other services achieved >90% accuracy and precision, validating behavioral analysis as a next-generation detection approach. Also supported PME subscription onboarding, localization pipeline security fixes, and knowledge-sharing sessions to strengthen team capability.
- Integrated new technologies into existing systems, increasing capabilities and improving overall performance.
