Satyarth Kumar Prasad — IOS Engineer

I am a proactive and achievement-oriented Staff iOS Engineer with more than 12 years of experience delivering high-performance, scalable mobile products at large scale. My strengths span mobile architecture, performance engineering, and leading teams to build impactful, customer-centric features. At Walmart Global Tech, I work in the Last Mile Delivery team, leading the Spark Driver mobile experience. I lead performance improvement initiatives, scale strategic delivery programs like Walmart Depot Delivery, and mentor engineers to drive technical excellence and execution quality. Before Walmart, at AiDash, I built scalable mobile solutions for operations management. I collaborated closely with cross-functional teams while mentoring engineers to elevate overall technical capabilities. Earlier at Upstox, I contributed to high-performance mobile architecture in a hyper-growth fintech environment. Key achievements include replacing Realm DB with ObjectBox (DB reads 10× faster, writes 3× faster) and boosting app socket performance by 80% via a shift from JSON APIs to gRPC, significantly enhancing realtime trading performance for millions of users. I began my journey at SplashLearn, where I progressed from Software Engineer to Lead. I led a team of 5+ iOS developers, building interactive, gamified learning apps using UIKit, Objective-C, Cocos2D, and Cocos-2D-js. I delivered complete product cycles; from requirements to App Store launch; helping millions of children learn math in a fun, engaging way. I thrive on solving complex technical challenges, enabling product innovation, and empowering teams to deliver high-quality engineering outcomes at scale.
