  • MyKolbeh2025 to 2026
    AI/ML Engineer

    Built a GPT-4o photo-and-text valuation model that cut pricing error (MAPE) from 19% to 14%, about a 26% relative drop. It was fed by an XGBoost pricing engine with seasonal and lag features and a GPT-4o-mini agentic crawler that auto-collected competitor listings.

  • HABIBI Lab, Sharif University2024 to 2025
    Research Assistant

    Combined ensemble feature extraction with a PPO agent for file-level software defect prediction, gaining +6.25% F1 over baselines on the PROMISE dataset, and co-authored the SDPERL preprint.

  • RIML Lab, Sharif University2023 to 2024
    Research Assistant

    Trained a patch-based MobileNetV3 classifier to 95% accuracy for counterfeit black-tea detection, the best of five architectures tested against RegNetY, EfficientNetV2, ShuffleNetV2 and SwinV2T. I also benchmarked classical models on VIS-NIR spectra under rising training noise, where ridge held above 0.95 accuracy while the ensembles degraded sharply, and used SHAP to trace pinto-bean adulteration to the 1400 to 1500 nm water band. Three papers came out of this work, in Horticulturae, Acta Technologica Agriculturae and Discover Food.

  • RADIAN Lab, Sharif University2023 to 2024
    Research Assistant

    Designed synthetic-data pipelines (GANs, VAEs, Gaussian mixtures) for WiFi-CSI crowd-size estimation across multiple rooms, raising accuracy from 30% to 43% on unseen environments.

  • Dezpart Gohar Kimia Sepehr2024
    IoT Intern

    Instrumented a zinc-sulfate production line with a networked IoT sensor array and trained time-series models to forecast throughput bottlenecks hours ahead, surfaced in a real-time dashboard whose threshold alerts cut unplanned downtime by about 15%.
