I'm Abhinav Yadav, a freelance AI/ML Consultant and Technical Solutions Architect. I help businesses automate complex spreadsheet workflows, develop and deploy custom AI/ML applications, build relational database systems, and create modern web apps. Additionally, I mentor university students globally in computer science, database design (Access DB/SQL), and data analytics (Tableau/Statistics). I focus on translating complex data problems into robust, clean code that creates immediate value.

AI, ML & Web Dev

From time series forecasting models and custom recommendation systems to generative AI agent workflows and responsive Next.js apps, I develop production-grade code that solves actual business problems.

Excel & BI Automation

Boost your productivity with custom VBA macros, advanced workbook models, dynamic formulas, and interactive Tableau/BI dashboards. I streamline your data workflows and eliminate manual spreadsheets errors.

DB & Tutoring Support

Need help designing Access DB structures, writing complex SQL queries, or setting up relational schemas? I also offer 1-on-1 tutoring, code reviews, and academic project mentoring to help you succeed.

Data Scientist @ Cognitio Analytics Inc

MAPE < 10%100% Automated Drift Detection

Predicted 12-month PLPM costs enabling client risk management and premium planning.

Established automated model health checks ensuring high stability and accuracy.

Automated model retraining reducing manual ML operations overhead by 90%.

Detailed Responsibilities

•Developed time series forecasting models to predict 12-month PLPM (Per Life Per Month) cost for an insurance client using regression and boosting approaches, achieving less than 10% MAPE.
•Implemented an automated model monitoring framework to track prediction accuracy, detect data and concept drift, and evaluate model stability over time.
•Built scheduled retraining pipelines that automatically trigger model retraining and deployment when monitoring thresholds or performance metrics degrade.
•Performed exploratory data analysis (EDA) and feature engineering on large healthcare/insurance claims datasets using Python and SQL to improve forecasting reliability.
•Collaborated with actuarial, product, and engineering teams to integrate cost forecasting outputs into analytics systems for premium planning and risk management.
