About

Hey, I’m a Software Engineer 2 at Microsoft with 4.5+ years of experience building large-scale, user-facing, and AI-driven products across Copilot, enterprise integrations, and cloud-based microservices. I specialize in architecting distributed systems, designing scalable backend services, and delivering end-to-end product features that improve reliability, performance, and user engagement. My recent work focuses on Microsoft Copilot - including orchestrated multi-agent systems, deterministic agent handoff, extensibility frameworks, compliance-ready features, and next-gen chat experiences. I’ve led full-stack and backend initiatives across C#/.NET microservices, Ruby on Rails, GraphQL, TypeScript and React, consistently reducing latency, improving availability, and building features used across the M365 ecosystem. Alongside this, I’ve also delivered deep integrations across Microsoft Teams, enabling cross-ecosystem collaboration and contributing to a 2x increase in MAU. Earlier in my career, I led enterprise identity and onboarding flows - SCIM provisioning, SAML SSO, and OAuth for platforms like Okta and Azure Active Directory, strengthening security and onboarding reliability for large enterprise customers. My engineering approach blends strong system design, product intuition, and a competitive programming background (Codeforces : 1862 (Expert) and CodeChef : 1994 (4*)), enabling me to build resilient systems, navigate complex technical spaces, and deliver high-impact features at scale. I thrive in roles where AI, distributed systems, platform engineering, and end-to-end product ownership converge.

CoPilot Development: Pioneered the Employee Self Service Copilot using Sydney/Avalon with Microsoft Copilot Studio to manage multiple responses and develop custom engine copilots. Focused on authoritative and non-authoritative responses, and built extensions to read action and topic configurations from CPS, using Avalon as the orchestrator.
Agent Handoff: Delivered deterministic agent handoff in ESS, routing queries to ISV/LoB agents
(Workday, ServiceNow) via maker-configured rules with full context preservation and @mention support.
AI Hub Workplace: Built the Workplace module in AI Hub, enabling users to get reliable answers to their Workplace-related queries. Developed multiple end-to-end functionalities including an enhanced chat experience that supports agent - user conversations with feedback, copy actions, interstitial text, suggested replies, and rich user input such as file and audio uploads.
Agent Disclaimer: Built the capability to associate a customised disclaimer with any agent, configurable by creators in the configuration layer or manually through the agent manifest. Owned the design and end-to-end implementation of Agent Disclaimer across the Copilot rendering layer, Admin Center configuration UI, Copilot Studio, manifest surfaces, and Substrate Search indexing, collaborating closely with partner teams to deliver a compliance-ready and localisation-friendly experience.
