Haikal Fikri Luzain

Software Engineer with 5+ years of experience building scalable backend systems and full-stack web applications, primarily in e-commerce, automation, and internal platforms. I specialize in backend development, system scalability, and performance optimization, with hands-on experience using Laravel, Golang, Node.js, and TypeScript. I’ve worked extensively with Elasticsearch for search and ranking optimization, as well as cloud-native and serverless architectures using AWS. Throughout my career, I’ve focused on solving performance and scalability challenges from optimizing slow database queries and implementing indexing strategies, to designing efficient APIs, microservices, and async processing workflows. I’ve contributed to features with real business impact, including search improvements, high-throughput notification systems, and product features that directly increased revenue. I enjoy collaborating across backend and frontend teams and have experience working with React, Next.js, Nuxt, Tailwind CSS, and modern CI/CD pipelines.
