About

I've spent about 10 years on frontend systems that most people never think about, which is usually the point. Users don't notice the stack. The engineers who inherit it don't have to fight it. When both are true, I've done my job. Most of what I've worked on has been hard problems wearing product clothes. At JustDoc it was a WebRTC video stack for doctor consultations that had to stay up with 200 simultaneous calls. At Infomedix it was coordination tooling across more than ten hospital departments, which is messier than that number makes it sound; care delays dropped around 40% once it went live. At Palo Alto Networks I've been running the frontend infrastructure behind our cloud security products. Nobody really talks about it, which is the outcome I was going for. I care about caching strategies and Redux state trees. I also care about why a finance team at one of our customers was still exporting spreadsheets by hand when the analytics engine we shipped could have saved them an afternoon. To me those aren't separate problems, even though they usually get staffed that way. Right now I'm a Principal Engineer at PANW, promoted from Senior Staff last year, leading frontend architecture for cloud management across AWS and Azure. Stack is React, TypeScript, GraphQL, Redux Toolkit. Most of my actual time goes into making sure twelve engineers aren't solving the same thing three different ways. What I'm after next is somewhere the frontend architecture is load-bearing. Somewhere the decisions I make actually affect what the product can become, not just how it looks.

Work experience

Principal Software Engineer at Palo Alto Networks, Feb 2025 - Present · 1 yr 10 mos, • Took ownership of the technical roadmap for cloud NGFW lifecycle management. The old process was manual, error-prone, and nerve-wracking for customers doing firewall upgrades. We replaced it with per-provider version control, automated rollback, and a full audit trail. Deployments stopped being something people dreaded. • Setting the architectural direction for how our frontend scales — micro-frontend boundaries, SSR adoption decisions, performance budgets, design system consolidation. These aren't glamorous problems, but getting them wrong compounds fast at enterprise scale. • Mentoring engineers on the team, not just on code but on how to think about tradeoffs. What to optimize for, when to push back on product, how to make a technical case to non-technical stakeholders. • Designed a modular, dimension-based analytics engine using Chart.js, empowering customers with self- service usage reporting, CSV exports, and complex date-range filtering, which reduced reliance on manual support requests.

Senior Staff Engineer at Palo Alto Networks, Apr 2022 - Jan 2025 · 2 yrs 10 mos, Bengaluru, • Built the Cloud Management Service (CMS) from scratch. It's a dashboard that lets enterprise customers manage firewall credit allocation across AWS and Azure. Nothing like it existed before. I owned the architecture and got it to production. • Hit a performance wall in the Redux layer. Redundant fetches, cascading re-renders, visible lag on the data-heavy views. I led a re-architecture of the caching layer (smarter invalidation, fewer round trips). Client-side response times dropped 25%. • The team was burning too much review time on stuff tooling should catch. Added pre-commit hooks, commitlint rules, and quality gates in CI. Review cycles fell ~30%. People finally started reviewing logic instead of whitespace. • Migrated the auth stack from Cognito to Okta. Login flow got cleaner and the security team stopped worrying about it. • Moved deployments to GitLab CI/CD with preview environments for dev, staging, and gov. PR-to-"does this actually work in a prod-like env" went from hours to minutes.

Software Developer at Clinivid, Oct 2018 - Mar 2022 · 3 yrs 6 mos, Bengaluru, • Developed a healthcare collaboration platform for multidisciplinary clinical teams, enhancing real-time coordination. • Led the MDT module across 10+ clinical departments, significantly reducing care delays by approximately 40%. • Engineered the application using ReactJS and Node.js, ensuring seamless functionality for over 500 healthcare professionals.

Software Developer at Labyrinth Technologies, Dec 2017 - Sep 2018 · 10 mos, Bengaluru Area, India, • Developed the AGNT platform using ReactJS and Redux, enabling artists and event organizers to manage bookings and collaborations effectively. • Created an e-commerce platform for independent design brands, featuring real-time messaging and an admin portal for streamlined storefront management. • Contributed to a user base of over 200 across 5+ countries for AGNT and launched with 600+ listings for the e-commerce platform.

Software Engineer at JustDoc, Aug 2015 - Nov 2017 · 2 yrs 4 mos, Greater Bengaluru Area, • Developed and maintained web applications and REST APIs for JustDoc's telemedicine platform, serving over 5000 registered patients. • Engineered a robust WebRTC video consultation stack using Socket.io, Node.js, and Redis, achieving 99.5% uptime. • Collaborated in a fast-paced startup environment, utilizing technologies such as AngularJS, Express, and PostgreSQL.
