About

I’m a Software Engineer with 4+ years of experience at Microsoft, building scalable, high-performance web and backend systems for Viva Learning, a core part of Microsoft Viva suite. My work spans React, C#, GraphQL, and Azure, with a focus on performance optimization, large-scale data integrations, and developer experience automation. I enjoy solving complex technical problems — whether that’s reducing API latency from seconds to milliseconds, migrating multi-tenant systems with zero downtime, or integrating AI-based review agents into engineering workflows. I thrive in environments that value end-to-end ownership, cross-team collaboration, and engineering excellence. My goal is to build systems that are not only fast and reliable but also make life easier for developers and end users alike. Key strengths: • System & API Design | GraphQL | REST | Azure • Performance Tuning & Caching Strategies • React | TypeScript | Frontend Infra Optimization • Cross-Product Integrations | Data Migrations | Observability • AI-Assisted Dev Workflows | Developer Tooling Currently exploring opportunities that combine system design, large-scale engineering, and intelligent automation, where I can continue to grow as a technical leader and problem solver.
