## Who

I'm Dhruv Mishra, a software engineer based in India. I work at Microsoft on the M365 Shell Team, focusing on systems that have to be fast, reliable, and boring in production. CS & Applied Math graduate from IIIT Delhi, Codeforces Expert, and a hobbyist across gym, chess, PC overclocking, and longevity research.

Current role: Software Engineer at Microsoft on the M365 Shell Team (since June 2024, Noida, India). The Shell service handles identity and user data at 7B+ hits per day. I work with C++ and C# on enterprise encryption flows, including PDF encryption for Office docs across Word, Excel, and PowerPoint — sandboxed via a secure C# proxy + IPC architecture talking to Azure Rights Management. Cut infrastructure COGS by $240,000 annually by optimizing VM Scale Sets, log retention/replication, and Redis/Cosmos configurations. Also designed autonomous LLM + MCP server workflows for the Identity Management Service to automate internal platform tasks and accelerate incident mitigation.

Favorite language is C++. Core stack: TypeScript, C++, C#, Kotlin, Python, SQL, Java, JavaScript. Frameworks and tools include Android (Jetpack Compose, XML, Gradle, Maven), React, Next.js, Tailwind, OpenCV, scikit-learn, DevOps, Git, NPM, Azure, GCP, Nginx, Cloudflare, MCP, LLM tooling, RAG, embeddings, and cryptography. Comfortable across system design, distributed systems, CI/CD, cloud infrastructure, REST APIs, databases, and machine learning.

This portfolio is a sketchbook-themed site built with Next.js 16, React 19, Tailwind v4, and Framer Motion. It has an interactive retro terminal, an AI chat, a guestbook, and an unlockable sticker system. Georedundant deployment across Oracle Cloud, GCP, and Azure VMs with custom traffic routing, Nginx reverse proxies, Cloudflare caching, and separate GitHub Actions deployment pipelines — everything free, only paying for the domain.

## Current and past work

Software Engineer at Microsoft (June 2024 to present, Noida, India). Highlights from the current role:

- Enabled PDF encryption for Office documents across Word, Excel, and PowerPoint by sandboxing the end-to-end execution of an existing C++ encryption SDK. Replaced direct network access with a secure C# proxy + IPC architecture for Azure Rights Management Service communication, reducing attack surface.
- Cut infrastructure costs by $240,000 annually for a shell platform backend service handling 7B+ hits per day by optimizing VM Scale Sets, log retention and replication, and Redis/Cosmos configurations.
- Designed autonomous workflows for Microsoft Shell Platform (Identity Management Service) using LLMs, MCP servers, and REST APIs to automate internal platform tasks and accelerate incident mitigation and bug resolution.
- Re-architected Excel's Compose shimmer loading path with warmup sequences, baseline profiles, and optimized XML/Compose interactions, reducing load time by 99% (300ms to 3ms) and improving perceived latency for millions of users.
- Achieved 100% security compliance as the Sole Security (S360) Compliance Owner for Office Android Shared.
- Primary owner for Fluent UI Android, driving 10 major releases used by 10+ partner teams including Copilot, Office, Outlook, OneDrive, and Teams. Migrated and owned publishing pipelines for Fluent UI System Icons.
- Won the Microsoft E+D FHL Award (Fundamental Category) for "WXP ActionEase".

Machine Learning Engineer at growIndigo (February 2024 to June 2024, Delhi, India). Replaced a manual Google Earth Engine classification workflow with a Python-based XGBoost and Random Forest pipeline, improving crop classification accuracy from 80% to 93% while significantly reducing workflow time.

Software Engineering Intern at Microsoft (May 2023 to July 2023, Noida, India). Architected a connection management service for Microsoft Loop that synchronized connection states across multiple third-party integrations (Jira, Trello, GitHub) — that service now serves as the generic backend for all third-party integrations. Integrated GitHub and Azure DevOps REST APIs into the Microsoft Power Platform Connector, enabling automated workflows. The GitHub connectors I built there are now used across major Microsoft applications.
