AppNexus was acquired by AT&T and merged to Xandr.I belong to the Prebid Server Team, a group of software engineers in charge of coding improvements and new features into Xandr's Prebid-Server. PBS, for short, is an open source project written in Go and hosted on the website https://github.com/prebid/prebid-server where I can be found under the username guscarreon as a contributor of thousands of lines of code (https://github.com/prebid/prebid-server/graphs/contributors). Because of my end-to-end knowledge of PBS source code, I'm also in charge of reviewing changes that other programmers want to code into it.Prebid-Server is very well positioned in the online advertising industry because it allows content creators to get the most revenue out of the sale of their advertising space on their websites, blogs, long-form videos, and mobile apps with an online auction technique called real time bidding. This product has become a central component of the company's very ambitious scope of projects in the advertising industry that include video streaming ads and mobile phone ads.I was also assigned complete ownership of another very important Xandr project also written in Go: Prebid Cache. PBC, for short, is an open source project hosted on the website https://github.com/prebid/prebid-cache where I can be found as a contributor under the username guscarreon . I’ve been the developer who has contributed the most lines of code and updates in the past 2 years to this repository. (https://github.com/prebid/prebid-cache/graphs/contributors)As of June 2022 on top of continuing being a contributor of Prebid Server and Prebid Cache, I was also assigned to become a contributor to Impbus, Xandr’s most ambitious project written in the C programming language.

Backend development in a Healthcare application that processes thousands of claims and big data. The system has a huge code base of C, C++, Pro*C and C# programs as well as C shell scripts. I get assigned change orders (CO´s) to write or modify the components written in C and Pro*C. I’m required to understand the code, engineer solutions, watch time and space complexity and test for both functionality and performance.In the past years, I’ve become proficient in Vim, Tmux, shell script, SED, the C++ iostream library, and POSIX regular expressions. These tools were not required to fill my present position, but I learnt them on my own and they have proven to be critical on a daily basis.C experienceMost of the last year I’ve been developing data conversion programs in C. Huge XML files have to be read in order to update or read from a database. Advanced C and Pro*C are critical. Both time and space complexity have to be watched closely because the programs are carefuly scheduled to run and performance very important. Warning and defect free code has been always required. Defective code correction of both UI and batch healthcare programs. This activity demanded problem solving skills, C language in depth knowledge, understanding of Coverity’s output, compiler error messages, and strong learning abilities. Defects on C-written source code were entangled in an even bigger code base than that of the UI modules, Shell scripting and data mining were everyday tools to find the correct solution approach. Some of the main C-language defect categories where: logically dead code, string length miscalculations, unsanitized strings, memory leaks, among others.I was involved in a code migration project of a healthcare application written in C from Solaris to an HP-UX server. The code was also converted to 64 bits. Strong bash scripting and C language knowledge was required to get onboard.

I put into HTML files undergraduate program course-content with the required SCORM format and style used in the University´s Moodle based e-learning system. I managed to automate repetitive copy-paste tasks and generate files faster using Java´s I/O classes.

Time and motion study using the MOST methodology. Product and model design with Autocad 2011.Wrote a simulation script in Javascript to redesign the job shop layout puting optimization algorithms into my code to find a near optimal solution to the machine-cell location problem. The new production cell system reduced operation time and process inventory.
