Saurav – AI agent development, RAG, SQL

Microsoft's internal developer platform for accessing cloud resources to test and deploy production resources to the cloud.

• Built a retrieval-augmented documentation assistant on Azure OpenAI and Azure AI Search over the Commerce testing team's knowledge base.
• Owned retrieval, embeddings, and citation-grounded answers to minimize hallucination.
• Maintained a continuously synced knowledge base supporting about 100 queries per week and reduced support tickets by about 30%.
• Built bot-fraud prevention for Azure signup at millions-of-users scale using behavioral-telltale CAPTCHA and risk-system learning.
• Reduced fraud by about 95%, saved about $25M per year, and retired an abused phone challenge with no regression.
• Led a live migration of 25M transactional records to multi-region Cosmos DB using dual-write, backfill, shadow reads, and cutover.
• Improved performance by about 50% with higher reliability.
• Modernized an internal developer platform across global Azure, US Government, China, and sovereign clouds.
• Deprecated a decades-old system and re-architected it for cloud scale and the AI era.

Always-on Windows security agent — real-time monitoring, AI-powered correlation, auto-remediation, and audit modules with compliance profiles.

• Built 33+ automated Windows audit modules targeting Firewall, Registry Hardening, Network Exposure, Defender, and System Accounts using native OS APIs.
• Created an interactive CLI fix engine (winsentinel fix) for automated, single-command system hardening and policy enforcement.
• Embedded local LLM inference engines (Ollama / Llama 3) to provide offline, natural-language security advice without cloud data exposure.
• Contributed to tuning specialized Llama 3 models (WinSentinel-Llama3.2-3B) for Windows event log parsing, threat classification, and severity scoring.
• Designed the centralized management framework allowing lightweight agents to report security posture and receive remote policy updates.
• Built low-overhead background monitoring services that deliver native Windows toast notifications upon detecting security anomalies.
• Authored report generators exporting security assessments into PDF, HTML, JSON, Markdown, and SARIF formats for compliance audits.
• Developed secure, encrypted command channels enabling fleet-wide remediation and bulk security policy execution across nodes.
• Distributed the solution as a .NET 8 global tool via NuGet (dotnet tool install), streamlining installation for sysadmins and developers.
• Created legible, color-coded CLI scorecards and progress indicators to make complex security status instantly digestible.

Customer-facing web applications in the digital-health and patient-engagement space.

• Developed responsive, touch-first web application interfaces optimized for wall-mounted digital displays used by physicians and patients during consultations.
• Integrated interactive 3D anatomical models (using WebGL / Canvas) enabling doctors to manipulate, annotate, and explain medical conditions dynamically.
• Created an intuitive UI for searching and launching specialty-specific educational videos, condition overviews, and treatment guides.
• Optimized client-side rendering, asset caching, and touch-gesture responsiveness for high-durability kiosk environments.
• Designed secure web and mobile architectures, ensuring zero persistent Protected Health Information (PHI) exposure on public-facing exam room hardware.
• Contributed to web management APIs that track device uptime, app health metrics, and content engagement analytics across thousands of deployed clinical screens.

Large-scale clinical software used by major hospital systems.

• Developed secure data pipelines to ingest, validate, and process high-volume electronic prescriptions directly from Epic EHR and external providers via Surescripts.
• Engineered backend services for real-time inventory tracking, lot allocation, barcode scanning, and automated fill-and-dispense verification workflows.
• Integrated automated drug-drug, drug-allergy, and dosage check validation engines during the prescription intake and verification pipeline.
• Built automated claim adjudication engines that interface directly with PBMs (Pharmacy Benefit Managers) for real-time copay, coverage, and insurance verification.
