Experience

Senior Director of Generative AI
Shutterstock – Dublin, Ireland
July 2023 – Present

Shutterstock is a global content marketplace where contributors license media assets (images, videos, music) to customers. Generative AI presents both disruption and opportunity to this model.

I lead four cross-functional teams responsible for delivering safe, high-performing Generative AI products and data services across Shutterstock’s platform and enterprise offerings. This includes real-time image generation via credits-based APIs, dataset curation for multi-million-dollar licensing deals, and strategic partnerships with OpenAI, Google, Amazon, Databricks, and NVIDIA. Our image generator achieves 70%+ monthly retention and is rapidly gaining market share in stock photography—outpacing other major media categories on the platform.

Key accomplishments:

• Model Performance & Personalization: Delivered a 30% lift in conversion rates through prompt optimization and dynamic parameter tuning systems. Built a context-aware generator selection framework that automatically chooses the most effective model based on user prompts and page context, boosting conversion by a further 20%+. Enabled independent experimentation by creating a custom traffic-routing infrastructure for ML scientists.

• Safety and Indemnity: Launched automated moderation pipelines with ~100% recall in critical brand safety categories (e.g., child safety) while maintaining high precision to minimize false positives and protect contributors. Additionally, led the development of computer vision models to detect AI-generated content across image submissions. These systems support the scalability of human moderation workflows, allowing our review team to handle the increasing volume driven by generative content creation.

• Dataset Delivery & Model Training: Lead the teams focused on dataset curation and delivery for enterprise AI clients. Collaboratively built a custom Stable Diffusion model with Databricks by applying targeted fine-tuning techniques and metadata enrichment strategies. This resulted in the creation of qualitatively validated and commercially differentiated data assets used to power downstream training and evaluation pipelines for generative and multimodal AI use cases.

VP of AI & Engineering
Streetbees :: London & Lisbon (Remote)
Oct 2021 - July 2023

Streetbees is a Series-B funded AI SaaS service that helps brands like PepsiCo and Unilever understand market trends by aggregating insights from over 3.5 million customers. This is done via an AI-powered mobile chatbot platform that drives open-form surveys, automates survey response annotation, and delivers machine learning-driven market insights.

I led the technology organization (>50 members), divided into three stream-aligned teams: acquisition, annotation, and reporting. Each team included engineering managers, software developers, data scientists, DevOps, QA, and data analysts. I was responsible for the technical and scientific strategy across the organization, ensuring each team could operate autonomously.

Notable achievements under my leadership:

• Aquisition: Reduced human moderation time for fraudulent image submissions by 75%. Our algorithm automatically identified over 80% of near-duplicate image submissions and screen captures as part of a review recommendation engine.

• Annotation: Cut manual coding costs by over 60% by upgrading a legacy text-only classification system. Our cross-modality deep learning model increased automated code discovery by over 300%, removing the need for extensive manual annotation in primary survey domains (such as beauty).

• Reporting: Fully automated the survey curation, delivery, and research report creation using GPT-3. This innovation cut the end-to-end client delivery time from over two weeks to days. This has ultimately led to a company pivot and the launch of a new product, Streetbees-X.

Head of NLP Centre of Excellence
Zalando :: Berlin (Remote)
Jul 2020 - Oct 2021

Zalando established four Centres of AI Excellence to drive innovation across areas such as NLP, Image Processing, Econometrics, and Forecasting. These centres enabled and seeded teams across Zalando with cutting-edge technologies.

I set up and led the NLP Centre of Excellence. I was responsible for the technical, product, and scientific direction of the centre. The team, consisting of 10 senior researchers, product managers, data engineers, and a data analyst, incubated technologies and supported the formation of new product-focused research teams across Zalando.

Key accomplishments include:

• Platform Capabilities: Developed a GDPR-compliant, multilingual customer feedback search and message routing tool. This platform ingested data from 18 languages across 40 customer touchpoints, consolidating all customer feedback into a single platform.

• Content Moderation: Incubated an automated moderation team for product safety issues flagged by the customer returns process. The tool, based on our state-of-the-art research, achieved over 95% recall in flagging unsafe products, expediting their removal with human-in-the-loop escalation to the manual inspection team.

• Product-Led Scientific Advances: Developed novel text clustering techniques for identifying new categories of customer feedback and product risks. We also pioneered a zero-shot classification technique using transformer architecture and contributed to the Flair open-source NLP project, originally developed by Zalando Research.

Supervisory Board Member
Zalando SE
May 2018 - Jun 2020

I served as a member of Zalando’s 8-seat supervisory board, working alongside key shareholder representatives including Cristina Stenbeck (Kinnevik), Anders Holch Povlsen (CEO of Bestseller Group), Kelly Bennett (CMO of Netflix), Mariella Röhm-Kottmann (KPMG), Alexander Samwer (Rocket Internet), and fellow Zalando employees Konrad Schäfers and Beate Siert.

The board was responsible for fiduciary oversight of Zalando. This included making decisions on significant policy changes, investments, divestitures, executive promotions, remuneration, and managing relationships with strategic investors and key brand partners.

Head of Customer Data Platform
Zalando
Jan 2016 - Jul 2020

Zalando, Europe’s largest fashion e-commerce platform, expanded its technical workforce in 2015 by opening new technology hubs in Dublin and Helsinki.

I was a founding member of the Customer Data Platform and progressed from Senior Scientist to Head of Applied Science. I led a team of 25, including managers, applied scientists, engineers, and product managers, organized into three teams: 1) Customer Preference Recommendations, 2) Customer Price Predictions, and 3) Cross Device Graph. We integrated services across Zalando’s main business units: Lounge, Markets, Zalon, ZMS, and Fashion Store.

Key accomplishments include:

• Customer Preference Recommendations: Our fashion attribute recommendation services, including category, brand, and price, powered customer preference collection, recommendation carousels, personalized navigation, gift card recommendations, newsletters, and offsite targeted advertising. These integrations drove double-digit improvements in A/B tests over existing solutions.

• Audience Targeting: Our predictive audience generation tools, used by ZMS, Zalon, and Markets, achieved up to 40x performance over legacy systems in early campaigns which externally drove client retention (ZMS) and internally enabled deeper market penetration (Zalon & Markets).

• Cross-Device Graph: Our cross-device graph improved advertising attribution by replacing the marketing team’s user association model. This led to a 40% increase in attributed sales significantly enhancing Zalando’s marketing performance. We also integrated this system into Zalando’s A/B testing platform, reducing test noise by double digits for cookie-based tests.
