Engineering @Cars24 | Platform & Backend Engineer

About

I am a Senior Backend / Platform Engineer (SDE-3) with strong foundations in computer science, distributed systems, and scalable backend architecture. I specialize in building high-impact platforms, reusable libraries, and business-critical services that operate at scale. At CARS24, I work on core backend systems powering consumer journeys, seller protection, and internal platforms. I have led and independently delivered multiple end-to-end features, improved system performance through targeted optimizations, and built configurable, multi-tenant libraries used across teams. Previously, at a fast-growing fintech startup, I worked on loan disbursement, repayments, lender integrations, and data pipelines, gaining deep exposure to financial systems, compliance flows, and production reliability. I am highly problem-driven, focused on clarity, ownership, and long-term system design rather than just feature delivery. I enjoy solving ambiguous problems, simplifying complex flows, and building systems that teams can scale with confidence. Tech focus: Java, Spring Boot, Microservices, Distributed Systems, SQL, MongoDB, Redis, Queues, Platform Engineering, Backend Performance & Scalability. https://shahzaibahmad3.github.io/portfolio/
