Vishal Nag

I am a Senior Mobile Engineer specializing in architecting cross-platform systems that scale seamlessly under heavy production loads. With over 7 years of experience, I bridge the gap between complex product strategy and high-performance engineering to deliver premium iOS and Android applications.
Most recently, I owned and optimized the core mobile architecture for a global B2B marketplace platform handling real-time data for over 10,000 active users. My focus was on eliminating friction across the digital commerce lifecycle. Key impacts included engineering low-latency search algorithms for massive inventories, securing international payment gateways, and architecting modular, high-performance dashboards using React Native, TypeScript, Expo, and GraphQL.
My engineering philosophy balances clean code with product velocity. I prioritize building maintainable software architectures that scale without accruing technical debt. To ensure reliability at speed, I establish robust CI/CD pipelines, automated Jest testing suites, and Datadog monitoring to mitigate regression risks and accelerate release cycles.
As a technical leader, I thrive in fast-paced, distributed environments, collaborating directly with international product stakeholders to transform business vision into production-ready software.
