About Me

I am a Data Scientist with a software-engineering backbone and proven experience delivering end-to-end AI and data-driven solutions - from data wrangling and feature engineering to modeling, evaluation, and scalable production deployment.

In prior roles, I modernized enterprise platforms in regulated settings - migrating legacy systems to a modern Python microservices architecture, designing secure APIs for core transactional workflows, executing large-scale data migrations with minimal downtime, and strengthening role-based authentication, encryption, and auditability. I also delivered operational data applications on Linux/cloud infrastructure and designed data pipelines that supported analytics for performance, risk, and resource planning. Across these projects, I introduced CI/CD and observability and shipped dashboards that turned operations into decision-ready insights while laying a foundation for ML.

To enhanced my predictive analytics skills, I completed Advanced Data Analytics Professional Certificates with real-time analytics and machine learning implementation, and I also earned Microsoft Azure AI Fundamentals (AI-900) to ground cloud-AI concepts.

Besides technical work, I take part in AI communities, mentor aspiring Python developers, and contribute to open-source projects - practices that keep me collaborative, innovative, and continuously learning.
