Dr Meharji A

FI-Helsinki

Senior Data Scientist & Applied AI/ML Engineer

Dr. Meharji A. is a highly skilled Data Scientist and Applied AI/ML Engineer (PhD) with 6+ years of experience in predictive modelling, recommender systems, and the practical application of artificial intelligence. His expertise combines hands-on ML/AI development with strong research rigour, enabling him to move effectively from understanding business needs and exploring data to developing, deploying, and operationalizing production-grade solutions.

He has substantial experience building end-to-end machine learning solutions, including data analysis, model development (predictive regressors, classifiers, and recommender systems covering retrieval, ranking, personalisation, and collaborative filtering), automated data pipelines, model architectures, APIs, and cloud deployment. His recent work has also included building AI agents (Google ADK, LangChain, CrewAI) and integrating Large Language Models via the OpenAI API into production data and ML workflows, including prompt engineering, data generation, and enrichment.

Meharji brings valuable cross-industry experience from banking and financial analytics, green energy financing, real estate/PropTech, and medical/healthcare-related data, allowing him to understand complex data-driven problems from both technical and business perspectives.
