WORK EXPERIENCE:

Confidential, Lakewood, Colorado

Application Developer

Responsibilities:

• Worked as a lead developer on standalone JavaFX - based application called Service Application for Material Inspection (SAMI), used to store inspection data for various assets for all Confidential and Wildlife refuges across the country, as well as calculating estimates of their development and repair. Used JSON arrays for data abstraction, Oracle (JDBC thin server) for database connection, and XSL for data transformation.
• Worked on front-end, back-end, and middle-tier for SAMI application modules (replacement value calculations, heavy equipment inspection, accessibility evaluation), created ETL process for loading asset data into the application.
• Participated in debugging, improving, and refactoring of the web-based DamSafety application, used to store inspection data and repair estimates for various dams across the country. Duties included database updates, front-end development (JSP), back-end and middle-tier development. Developed a logic for dams data exchange between SAMI and DamSafety projects.

Confidential, Denver, Colorado

Lead Application Developer
