About Me

More than just
clean code

Navy Submarine Veteran & Reactor Operator turned Software Engineer. Experienced in creating innovative solutions that enhance user experiences, I specialize in developing scalable web applications using cutting-edge technologies, bringing the same precision and discipline from the reactor room to every line of code. With a strong background in full-stack development, I excel in designing robust architectures and writing clean, efficient code.

2006's Time Magazine's person of the year. 2nd grade heads up 7up champion. I like donuts.

Senior Software Engineer
PKI & Identity Management
2015 — Present
  • Led the design and development of a PKI smart-card tokens and certificates life cycle management system.
  • Designed and implemented Role-Based Access Control (RBAC) dashboard management, allowing users to access personalized views based on their privileges.
  • Implemented a plug-in framework for seamless integration with trusted certificate authorities.
  • Developed a Django Restful API application server with certificate-based client-server mutual authentication, integrated with Nginx and MariaDB (MySQL). Implemented newer versions of the APIs with plain Python.
  • Developed a schema-driven system to gather and consolidate data from heterogeneous user, token, and certificate information sources.
  • Built modular .NET projects with MSSQL backends that communicate via well-defined service interfaces.
  • Leveraged Bootstrap 5 and React to enhance the user interface and improve usability.
  • Implemented Datatables server-side processing for real-time searches, ensuring optimal performance and scalability.
  • Integrated the dashboard with external packages such as Outlook, Acrobat DC Pro, and 90meter smart-card reader/writer.
  • Developed Python programs for PDF document form editing and dual certificate-signing.
  • Deployed several versions of the dashboard on-site at client locations, providing technical support and training.
  • Integrated client feedback into the development process to ensure the final solution meets their expectations.
  • Embraced Agile/Scrum methodologies for efficient project management and timely delivery.
