Rahul Bagai
Senior Software Engineer with 15+ years of experience building scalable backend platforms, distributed systems, cloud infrastructure, and AI systems across AssemblyAI, Meta, and Expedia Group. I specialize in AWS, Kubernetes, Terraform, Python, Java, microservices, APIs, platform engineering, CI/CD, and large-scale SaaS architecture.
I have built and led systems supporting 30M+ users, reduced cloud infrastructure costs by 70%, improved deployment speed and reliability through CI/CD and developer experience platforms, and worked on AI speech-recognition infrastructure that reduced transcription time by 42% and expanded automated language detection across 99+ languages.
I am seeking remote senior or staff-level backend engineering, platform engineering, cloud infrastructure, or AI infrastructure roles where I can design reliable systems, improve engineering velocity, mentor teams, and turn complex technical problems into measurable product and business outcomes.
