1. Java Developer

   Overland Sheepskin Co.

   Aug 2024 — Present · Fairfield, IA, US

   Developed and maintained data-centric applications using Java (Spring Boot) and ReactJS to support inventory, order, and customer data management systems. Leveraged Python libraries such as Pandas, NumPy, and SQLAlchemy for data manipulation, reporting, and database interactions across structured and unstructured datasets. Integrated multiple data sources, including Azure SQL, Cosmos DB to manage product catalogs, sales transactions, and user behavior data. Built responsive UIs in ReactJS for dashboards, administrative tooling, and reporting features (e.g. sales analytics, inventory insights, data governance pages). Created and refined microservices and RESTful APIs to centralize business logic and data access layers across modules (inventory, orders, user profiles). Implemented data quality, classification, and governance pipelines — including validation rules, tagging of data entities, missing value detection, and automated data-cleaning procedures. Developed batch jobs and schedulers (using Spring) to handle asynchronous workflows such as data synchronization, nightly ETL tasks, and bulk imports/exports. Deployed microservices with Docker and automated cloud infrastructure (e.g. Azure or AWS) using IaC tools, ensuring scalability and reliability. Collaborated with cross-functional teams (product, UX, operations) to align feature development with business rules, data privacy, and governance requirements. Used Git, Maven, and Jenkins / Azure DevOps for source control, build pipelines, and continuous delivery. Monitored application performance and data integrity via logging and dashboards (e.g. Splunk, Kibana), and optimized SQL queries and ORM mappings for better throughput.
