AI Executive Leader
I am an executive AI and platform leader with nearly 20 years of experience building and scaling AI organizations, establishing AI-first operating models, and translating advanced AI technologies into core platform capabilities for global enterprises. My work sits at the intersection of machine learning, product strategy, and organizational leadership, with a consistent focus on converting frontier AI innovation into durable revenue growth, operational leverage, and differentiated user value.
Since 2025, I have served as Vice President of Engineering – AI at Nokia, where I help to shape the company’s AI strategy and execution in support of its mission of Connecting Intelligence and shaping the next-generation architecture of the telecommunications industry. My mandate is to embed AI as a foundational layer across Nokia’s network, cloud, and software platforms. Our strategy is anchored in three platform-centric pillars:
- AI-powered engineering Software Development Life Cycle (SDLC): Modernizing the end-to-end software development lifecycle through state-of-the-art AI and developer productivity platforms, driving step-change improvements in engineering velocity, quality, and scalability across large, globally distributed telecom organizations.
- Agentic automation for Telecom operations: Building AI-driven automation platforms that transform Day 1 and Day 2 lifecycle management for cloud-native networks, delivering order-of-magnitude gains in operational efficiency, resilience, and simplicity across complex multi-cloud and hybrid environments.
- AI-native telecom platforms: Developing system-level, end-to-end optimization across network intelligence, cloud infrastructure, and workload orchestration—laying the foundation for an open telecom marketplace where AI workloads are deployed, optimized, and managed as first-class citizens across edge, cloud, and network domains.
Across this work, my focus is on positioning AI not as an incremental feature, but as a core architectural layer that drives convergence across networks, cloud infrastructure, and intelligent software systems.
From 2020 to 2025, I served as Director of Engineering – AI at LinkedIn, leading the Talent Marketplace AI organization (~60 ML engineers and applied researchers). I owned organic and paid job search, recommendation, and notification experiences, partnering closely with VP-level leadership to define AI-first product strategy and deliver LLM-powered experiences for job seekers and hirers. This work consistently generated ~10% engagement lift and more than $100M in annualized revenue growth per year across LinkedIn’s multi-billion-dollar Talent Solutions business. I previously served as AI lead for LinkedIn China and LinkedIn Sales Solutions.
Prior to LinkedIn, I led Data Science and Machine Learning at Etsy from 2016 to 2020, scaling a centralized organization from 5 to nearly 40 senior scientists and engineers across New York and San Francisco. The team delivered $120M in incremental GMV and $10M in annual revenue, powering search, discovery, personalization, and advertising through deep learning, causal inference, computer vision, and large-scale experimentation. Earlier in my career at Yahoo Research from 2013 to 2016, I managed research and engineering teams building personalization and ranking systems for products serving billions of users, achieving sustained double-digit engagement gains.
My research has been widely published (H-index 29, 6,900+ citations), recognized with the ACM RecSys Best Paper Award, and translated into patents and large-scale production systems. I am particularly passionate about:
- AI-first product strategy and marketplace design
- LLMs, recommender systems, and causal ML in production
- Building and scaling high-performing ML organizations
- Bridging research innovation with measurable business impact
I regularly keynote at leading industry and academic venues and contribute to the field through conference leadership and program committee service.
Tech Community Activities
From 2024, I started to give a series of invited talks on the topic “Supercharging Jobs Marketplace” at
- Keynote Talk at AdKDD 2024@KDD 2024 (August, 2024).
- Keynote Talk at AI4HR & PES@ECML-PKDD 2024 (September, 2024).
Between 2021 and 2023, I gave talks on the topic of “Computational Jobs Marketplace” at:
- Invited Talks: Chinese edition at SDCon 2023 (April 2023), CS Dept. at Michigan State University (April 2023), CBA AI Frontiers event (October, 2022), Southern Data Science 2022 (September, 2022), Melbourne Search and Recommendation Group Meetup (November, 2021), The AI Summit | Silicon Valley (November, 2021).
- Keynote Talks: Decision Making for Information Retrieval and Recommender Systems Workshop at The Web Conference 2023 (April 2023), RecSys in HR 2022 (September 2022)
And at the same time, I co-organized two workshops on the same topic:
- The Second International Workshop on Computational Jobs Marketplace as part of AAAI 2025.
- The Workshop on Decision Intelligence and Analytics for Online Marketplaces: Jobs, Ridesharing, Retail, and Beyond at KDD 2022.
- The First International Workshop on Computational Jobs Marketplace as part of WSDM 2022.
