About

Backend Engineer with 5+ years of experience building scalable, distributed, and high-performance backend systems. Over the years, I’ve evolved from solving core backend problems to designing reliable event-driven architectures focused on scalability, resiliency, and engineering excellence. Experienced in distributed systems, system design, backend architecture, and performance optimization, with hands-on expertise in Node.js, Kafka, MongoDB, Redis, microservices, and event-driven systems. Passionate about building low-latency, fault-tolerant platforms, improving system efficiency, and solving complex scalability challenges at scale. Beyond coding, I enjoy mentoring engineers, improving engineering processes, and driving production reliability through strong collaboration and continuous learning. Currently exploring AI-powered systems and modern distributed architectures. Interested in building high-scale, reliable backend systems in fintech and distributed environments. Always happy to connect with engineers and builders. 📩 Open to backend engineering roles — feel free to reach out.
