About Amit Tank

I’m a strategic engineering leader with 15+ years of experience defining technical vision, setting engineering direction, and executing at scale. I specialize in building cloud-native and on-prem platforms that are high-throughput, low-latency, and resilient—powering mission-critical AI/ML, personalization, and data systems. At Expedia Group, I lead cross-functional teams building next-generation AI-powered personalization, marketing, and advertising platforms driven by both Generative AI (LLMs) and traditional ML. I’ve defined and delivered a multi-year roadmap for real-time customer experiences spanning 16 global brands and 5 verticals. I architected and scaled a Customer Data & AI Platform processing petabyte-scale data, enabling real-time micro-segmentation and contributing $100MM+ in business impact. I designed high-performance APIs supporting 10K TPS with sub-millisecond latency and built both ML training and inference platforms. I also spearheaded GenAI-based agentic systems that now power 80–90% of development and migration workflows—turning LLM experimentation into measurable enterprise impact—while custom MCP servers handle large-scale data analysis and production support. Beyond technology, I drive clarity in strategy, KPIs, operating models, and cost optimization—resulting in a 26% productivity gain and 75% reduction in support costs. My leadership philosophy centers on strong technical foundations, cross-functional alignment, and disciplined execution to translate complex AI initiatives into tangible business outcomes. Core Expertise: • Cloud & Platform Architecture (AWS, Microservices) • AI/ML & Generative AI (LLMs, RAG, Agentic Systems, Personalization) • Big Data & Streaming (Spark, Kafka, HDFS, Presto, Hive) • High-Throughput Systems (10K–200K TPS, Low-Latency APIs) • Engineering Leadership & Org Scaling • Operational Excellence, Cost Optimization & Financial Management Passionate about shaping the future of AI-driven platforms and building systems that operate at real-world scale.
