CV

More than models. Measurable results.

Professional Summary

I’m Hriday Saha — a data scientist who blends business impact with technical precision. With 3+ years of experience across India, Malaysia, and France, I’ve led the design and deployment of 15+ production-grade ML solutions, from fraud detection platforms that saved $1.5M+ to intelligent audit systems that cut workloads by 96%. My work combines machine learning, NLP, and data storytelling to build systems that aren’t just accurate — they’re actionable, scalable, and built for real-world decisions.

Work Experience

Oct 2023 – Sep 2024

Data Scientist | AXA Group Operations, Paris, France

  • Built an NLP-driven semantic similarity system (BM25 retrieval + fine-tuned Sentence-BERT ranking + LightGBM scoring) to automatically map local audit issues to SAF controls.

  • Achieved 93% Top-1 and 99% Top-3 mapping accuracy, reducing manual workload by 96% (~$180K annual savings).

  • Designed explainable outputs (confidence scores, key-phrase highlights) to improve auditor trust and adoption.

  • Collaborated with DevOps teams to integrate models into enterprise workflows with retraining and drift monitoring.

Oct 2022 – Sep 2023

Data Governance & Analytics Project Manager | AXA Group Operations, Paris, France

  • Designed a real-time fraud detection platform using XGBoost ensembles with engineered features (transaction velocity, geo-mismatch, device fingerprints, graph-based merchant-user linkages).

  • Reached 94.2% F1-score, scaled to 1M+ daily transactions (<100ms latency), and prevented $1.5M+ in fraud losses annually.

  • Applied time-series cross-validation to handle fraud pattern drift, ensuring long-term robustness.

  • Managed a $1.2M analytics portfolio with 98% on-time delivery across data governance initiatives.

Sep 2021 – Sep 2022

Data Analytics Associate | AXA Group Operations, Kuala Lumpur, Malaysia

  • Engineered classification models and statistical validation pipelines (t-tests, ANOVA) to support risk analysis workflows.

  • Streamlined ETL and anomaly detection pipelines using Python, reducing data discrepancies by 80%.

  • Generated interactive Power BI dashboards with live KPI tracking, improving decision-making accuracy by 10%.

KEY PROJECTS & IMPACT METRICS

Automated Audit Intelligence System

  • Developed a two-stage ML/NLP pipeline (BM25 retrieval + fine-tuned Sentence-BERT ranking + LightGBM scoring) to link local audit issues with SAF controls.

  • Achieved 93% Top-1 / 99% Top-3 mapping accuracy, reducing manual audit workload by 96% (~384 hours/quarter, $180K annually).

Enterprise Fraud Detection Platform

  • Built an XGBoost-based real-time fraud detection system analyzing 1M+ daily transactions with latency <100ms.

  • Engineered features (transaction velocity, geo-mismatch, device fingerprints, graph link analysis), applied time-series CV, and attained 94.2% F1-score.

  • Mitigated $1.5M+ in operational risk losses annually.

Business Intelligence Optimization

  • Produced scalable customer segmentation dashboards using clustering algorithms (K-means, DBSCAN) tailored for regional markets.

  • Reduced manual reporting time by 30% and improved data-driven decision-making with a 98% delivery consistency.
