Kaspi.kz

Kazakhstan-based technology and financial services company.

Built and deployed ML systems for moderation, OCR, and video matching; improved automation by 8.12% and delivered video-matching recall of up to 99.67%.

• VLM Verification Layer: Introduced vision-language models as an automated post-check over four production classifiers, filtering borderline predictions to cut false positives and raise the overall automation rate by +8.12%. • Chinese OCR Service (PP-OCRv5): Built and shipped the full production pipeline — preprocessing, text detection, angle classification, recognition and structured post-processing — served as a batched FastAPI microservice in Docker with logging and failure handling.

Research Assistant

Nazarbayev University

Research university in Kazakhstan.

Implemented and validated an ADMM algorithm for constrained sparse group LASSO formulations in high-dimensional forecasting.

• Implemented the ADMM algorithm in R to optimize Multivariate Constrained Sparse Group LASSO formulations for high-dimensional forecasting, validating stability against analogous frameworks from the literature.

Computer Vision Engineer Intern

Scientia

Developed computer vision methods for box-corner and fracture-edge detection, including box-corner detection at 0.06 MSE.

• Automated box corner detection to 0.06 MSE with a ResNet-34 trained on a quadrant-based image division strategy and custom augmentation pipelines. • Built an ellipse-fitting mechanism for fracture edge detection using OLS regression, improving geometric precision in structural analysis.
