Hi, I’m Karan Jaiswal. I’m an SDE-2 iOS Engineer at Upstox, building high-performance, scalable mobile systems used in real-time financial environments. With 3+ years of hands-on experience in production-grade applications, I specialize in Clean Architecture, system design, networking, performance optimization, and writing maintainable code at scale. I focus on helping serious developers level up — whether that’s: • Breaking into product-based companies • Transitioning from service to product roles • Preparing for SDE-2 interviews • Strengthening iOS fundamentals & architecture thinking My approach is practical, industry-backed, and execution-driven — not just theoretical advice. If you're committed to accelerating your tech career strategically, let’s connect.
