Responsibilities:

  • Responsibilities include software development and managing/mentoring several programmers.
  • Performed software development on two key BioTrack products referred to as CORE and TRACE. The CORE application is a Windows based Client-Server multi-threaded application using two relational databases, Postgres and SQLITE. The application's graphic user interface is based on GNU GTK2 API. The application is built in PERL, PL/PERL, and SQL. The TRACE application is a Linux based Web application using Apache web server that communicate with multiple client CORE applications via a proprietary set of communication API. The Linux based web application is built in PERL, PL/PERL, and SQL. The application also relies on JavaScript, CSS, and Catalyst as well. The user interface is developed using PERL GTK3 API calls which are converted into HTML via a translation layer called Broadway. Development of communication functionality to interact with Restful APIs to access third-party web services.
  • Development was performed in VMware Windows and Linux as well as AWS Linux environments. Development is based on Agile methodology using JIRA for task management and Git for version control.
  • Developed and implemented software standards and guidelines as well as configuration management documentation for the company’s software development processes.
  • Provided mentoring, training, software code reviews, and additional technical guidance and direction when necessary.

Software Engineer

Responsibilities:

  • Developed multiple applications used to process model output, applying statistical analysis, and the generation of summary results used by scientist to interpret levels of salinity, stage, flow and other hydrological characteristics (PERL, C/C++, Python).
  • Developed client-server model metadata library application in Java using SQL Server for the backend. The application is used by modelers to upload model metadata thereby providing a historical record of all significant model runs for future reference.
  • Development of software tools and utilities used to simplify and streamline day to day processing activities as well as maintenance of existing tools
  • Lead a team of modelers to consolidate, eliminate, and reorganize model run datasets
  • Provided programming and development guidance to the modeling staff involved in the development of various applications
  • Ported multiple types of applications (PERL, C/C++, and C-Shell) from Solar UNIX to the Linux operating system.
  • Developed documentation and facilitated processes improvement to streamline operations
  • Requirements analysis and comparison of GNU/IBM compilers and debuggers

Consultant

Confidential, Miami, FL

Responsibilities:

  • Designed and developed three firewall security software applications using C/C++ and the SQL Server DB LIBRARY interface.
  • All applications interact with and modify the system’s security firewall via the BSD Firewall IPFW application interface.
  • Additionally, these applications updated user information in the SQL Server database using the SQL Server DB-Library interface.
  • The first application evaluates users to determine if they have exceeded their maximum logon time since authentication or have not transmitted any IP packets via TCP/IP within a dynamically specified time limit. If a user exceeds these constraints, they are disconnected from the system and will be required to re-authenticate.
  • The second system is used to reorganize and consolidate IPFW firewall entries to enhance performance and streamline the dataset.
  • The third application validates that the user is using the original MAC address that was used to initially logon to the system. This prevents unauthorized users from hijacking valid IP addresses and thereby prevents the bypassing of system security.
