# Jaik P. > Senior Software Engineer @ Capital One Location: New York City Metropolitan Area, United States Profile: https://flows.cv/jaik From powering contactless card systems used by 55M+ cardholders to building an enterprise tokenization platform processing over 10B records per day, I build infrastructure and platforms that scale reliably and operate with precision. I'm a backend-focused Infra Engineer with a track record of delivering high-volume, intelligent systems across secure messaging, enterprise data protection, and real-time customer experiences. At Capital One, I've architected core infrastructure for both internal platforms and external-facing services; contributing to ultra-high-performance systems, enterprise-wide applications, and SDKs used across my organization. My work spans secure APIs, partial data detokenization, and distributed services in Python, Go, and Rust. All deployed on AWS, designed for reliability, performance, and cross-team impact. Whether introducing intelligent real-time workflows or modernizing onboarding platforms, I lead projects end-to-end and thrive in complex, fast-moving environments. Feel free to reach out if you're solving complex engineering problems at scale and looking for system-minded builders. I'm always open to great conversations and bold opportunities. ## Work Experience ### Senior Software Engineer @ Capital One Jan 2025 – Present | McLean, Virginia, United States Building out Capital One's real-time messaging platform, designed to power intelligent messaging journeys for use cases across our enterprise through a low code contribution model. ### Senior Software Engineer (Principal Associate) @ Capital One Jan 2023 – Jan 2025 | McLean, Virginia, United States Full-stack developer responsible for realtime customer messaging and online banking services, catered towards Capital One's heavy spending small businesses.
