Varun K Nair — Senior Software Engineer

https://varunknair.com I'm a Senior Software Engineer with 9+ years of experience building scalable, cloud-native web applications, distributed microservices, and data-intensive pipelines across security, collaboration, and SaaS platforms. Currently at Proofpoint (Normalyze DSPM Team), I design and build critical components of our Data Security Posture Management (DSPM) solution. I work end-to-end—from orchestrating scalable data pipelines that extract, scan, classify, and assess risks in SaaS datastores (like Google Drive, OneDrive, SharePoint) to visualizing actionable insights on the frontend. Our data workflows span AWS, Azure, and GCP, with data aggregated into Snowflake and exposed via rich dashboard visualizations. My core expertise lies in: Backend Engineering with Node.js, Python, Temporal, AWS Lambda, Conductor Frontend Development with React.js, building reusable design systems and responsive UIs Cloud and DevOps: Snowflake, Docker, Redis, Kubernetes (beginner), Azure Container Apps, Terraform (basic) Distributed Systems & Event-Driven Architectures for real-time security insights Designing systems that balance performance, security, cost, and observability At Cisco, I contributed to key product lines like Webex and the Security Business Group, improving delivery through component reuse, better development workflows, and team mentoring. I enjoyed uplifting peers through mentorship, code reviews, and instilling best practices that supported a high-performing engineering culture. I thrive at the intersection of architecture, product thinking, and technical execution — leading initiatives, driving clarity across teams, and delivering high-impact solutions that solve real user problems. I'm passionate about mentoring, simplifying complexity, and collaborating cross-functionally to align tech with business goals.
