I'm a Senior Data Scientist who has worked on a range of AI, Machine Learning, and Cybersecurity projects including deep learning, forecasting, recurrent and convolutional neural networks, financial prediction tools, natural language processing models and much more. In addition, I also have full-stack development experience working with customers worldwide. I'm knowledgeable in technologies such as Python, Tensorflow, Pytorch, Scikit-Learn, Keras, JavaScript, ReactJS, NodeJS, Pandas Numpy, SQL, and much more. I have helped build AI projects in a range of sectors, web applications for startups, implemented DS models for e-commerce leading to higher sales performance and retention initiatives along with overall DS and AI related options for businesses of all sizes.

I design curriculum systems and AI-powered learning architectures for K-12 education. For 12+ years, I've built personalized learning programs at Think Prep (New York), helping students excel in competitive academics — Hunter/SSAT/ISEE/HSPT/SHSAT/SAT/AP prep, and gifted education. I know what works in the classroom. My teaching background is cross-curricular by necessity. I've taught AP Calculus alongside AP Physics, showing students how derivatives describe motion and integrals calculate work. From gifted elementary students to high schoolers preparing for AMC competitions, I've taught across levels and abilities — always emphasizing problems that blend geometry, number theory, and algebraic reasoning in a single question. This experience taught me that real learning happens at the intersections — and that most curricula fail to build those bridges. Now I work at the systems level: designing curriculum frameworks, and building knowledge architectures that align learning objectives across subjects and grade levels. What I deliver: -Curriculum audits and vertical/horizontal alignment -Learning management system design and EdTech consulting -AI-enhanced adaptive learning frameworks -Instructional content development (Math, Science, Test Prep) Whether you're an EdTech startup needing curriculum architecture, a school district redesigning scope-and-sequence, or a content company building adaptive courseware — I bring both classroom experience and technical depth.
