Berlin, Germany
Data Scientist at Bolt, one of the fastest-growing mobility companies in Europe, with 5+ years of experience building and deploying ML/AI solutions at scale. Previously worked on data science problems for some of the biggest pharmaceutical companies in the world at ZS. Skilled at taking ambiguous business problems and deriving specific, data-driven solutions.

About Me

Passionate about productionizing AI systems, from computer vision to LLMs. Recently built and launched CoverArtist.ai, a production LLM application that chains language and diffusion models to generate album artwork. Enjoy communicating complex results to both technical and non-technical audiences while driving product and business impact.

Experience

Bolt
Data Scientist
June 2022 – Present
Berlin
  • One of the earliest Data Science hires for the Micromobility vertical at a fast-growing European mobility startup.
  • Scaled DS team and initiatives while serving millions of users across 100+ cities.

Pricing Optimization Strategy

  • Architected a multi-model (including Bayesian hierarchical) forecasting system with business-knowledge-based priors and constraints to optimize pricing across pay-as-you-go rides and subscription passes.
  • Achieved a significant MAPE reduction from 14.14% to 8.7% while improving causal forecasting quality.
  • Built robust forecasting models using a Bayesian framework, handling multiple pricing scenarios across 100+ markets, guiding vertical-wide revenue decisions.
  • Reduced average forecast MAPE by ~5% across all cities, leading to much higher-quality forecasts and downstream pricing decisions based on the model.
  • Translated an extremely ambiguous business challenge (pass vs pay-as-you-go) into a structured, data-driven solution.
  • Designed an experimental framework to measure price elasticities and cross-elasticities between different product offerings.

Smart Collect

  • Led end-to-end development optimizing operational efficiency.
  • Defined the north-star metric (GMV per Collection Task) through stakeholder alignment.
  • Designed rigorous A/B testing with user-centric guardrails.
  • Drove a 2.7% improvement in the primary metric while maintaining user satisfaction thresholds.
  • Orchestrated the ML-based solution to a complex operations process end-to-end.

Computer Vision Solutions

  • Led ParkAssist project: defined parking quality standards, coordinated labeling efforts, and fine-tuned vision models to achieve 85%+ accuracy.
  • Processed millions of weekly parking validations across 100+ cities, improving operational efficiency and user experience.
  • Achieved best-in-class parking detection models (across all scooter competitors, from public tender evaluations).
  • Allowed operation in new markets and helped win tenders in existing markets, indirectly resulting in millions of new rides.
  • Developed tandem riding detection system using a first principles approach, crucial for regulatory compliance and winning city tenders.
  • Established a data-driven product development culture by operationalizing vertical-wide standard metrics for experiments and holding weekly data insights sessions with product and engineering teams to inform decision-making.
December 2023 – Present
Remote
  • Built and launched a production AI application that generates album artwork by chaining LLMs with diffusion models.
  • Designed and implemented end-to-end system architecture, from prompt engineering to model deployment.
  • Developed full-stack infrastructure using NextJS, handling user authentication and payment processing.
  • Engineered robust prompt optimization and model chaining pipelines for consistent, high-quality outputs.
  • Demonstrated ability to take an AI project from concept to monetized product, gaining hands-on experience with LLM development and deployment.
Carnot Technologies
Data Scientist
October 2021 – April 2022
Remote
  • Sole Data Scientist working on agri-tech solutions for a Mahindra-backed startup.
  • Wrote production-level Python code to analyze large-scale, noisy IoT data from on-board devices (OBDs) on tractors (2Hz sampling rate) to detect fuel theft.
  • Performed product usage analytics for an app with over 1 million registered users.
