Vinupriya Vairavan

I am a results-driven Senior Backend Engineer with over a decade of experience architecting and developing scalable, high-performance systems using Microsoft technologies. My core expertise lies in ASP.NET Core, C#, Azure (PaaS, IaaS, Functions, Service Bus, Event Grid, Cosmos DB), SQL Server, NoSQL, and modern front-end technologies like Angular, Blazor, and MVC Razor. I’ve consistently delivered large-scale, mission-critical applications that meet the complex needs of enterprise environments.

Throughout my career, I’ve designed and implemented distributed systems capable of processing over 100 million transactions and billions of events per day with a focus on resiliency, observability, and operational efficiency. My systems are built with cloud-native principles—leveraging microservices architecture, event-driven design, CQRS, and asynchronous messaging patterns for performance and scalability. I have a deep understanding of API security (OAuth2, OpenID Connect, Azure AD), DevOps practices, and infrastructure-as-code using ARM/Bicep and Terraform.

In team environments, I take pride in leading from the front—mentoring junior engineers, conducting design and code reviews, driving engineering best practices, and collaborating cross-functionally with product, security, and SRE teams. I champion clean architecture, SOLID principles, test automation (unit, integration, E2E), and continuous integration/delivery pipelines (GitHub Actions, Azure DevOps) to ensure velocity without compromising stability.

Beyond technical execution, I’ve contributed to system design discussions at both high-level and low-level granularity—translating business needs into scalable architectures, selecting appropriate data stores, partitioning strategies, and ensuring cost-effective performance tuning on cloud infrastructure.

Currently, I am preparing for Senior/Lead engineering roles at Tier 1 tech companies, focusing on sharpening my system design, DSA, and leadership skills aligned with FAANG-level expectations. I am passionate about solving complex architectural challenges, building resilient distributed systems, and delivering value at scale. My goal is to drive innovation and excellence in engineering teams working on real-world problems that impact millions of users.
