    Object Detection Deployment
    januari 2021 - januari 2022 (1 jaar)
    Developed and deployed a low-latency object detection system. Optimized inference per-
    formance by zero-shot learning and lightweight architecture design (YOLO) in PyTorch.
    Reduced deployment cost by replacing GPU servers with 2-core 8GB CPU instances while
    maintaining real-time detection performance for third-party client applications.

    Developed and maintained a high-volume financial payment aggregation system using Type Script,GraphQL,Nestjs and TiDB database. Integrated multiple third-party payment APIs
    and optimized ElasticSearch for large-scale transaction queries. Implemented CI/CD pipelines
    with JetBrains Space, Docker, and Kubernetes, and automated deployment scripts for
    production environments. Resolved complex database and API inconsistencies, improved fault tolerance, and enhanced system reliability through Python-based monitoring and order-tracking
    tools.

    PDF Information Extraction
    januari 2019 - februari 2019 (1 maand)
    Analyzed university curriculum dependency structures from PDF documents for a client. Due
    to dataset and budget constraints, designed a lightweight parsing approach based on PDF
    layout structure instead of traditional NLP pipelines, achieving high accuracy at minimal cost.
    The original estimated model training cost was about €1000, which was reduced to roughly
    €100 through structural parsing
