Luis A. Rodriguez-Condit
Technical Architect – Embedded & Web Systems
Summary
I'm a Senior Software Engineer with over 20 years of experience building software that ranges from video games for small resource limited mobile devices to web applications used by millions of users. I prioritize user experiences to help them achieve whatever their trying to do in a simpler, quicker fashion. I am capable of being an individual contributor, or leading teams where I use my organizational and emotional skills to deliver what the customer or business needs. In a mentor or lead role, I tend to be empathetic, looking for ways to keep the team's morale up so we can all be more efficient. Overall I love to design, write and deliver software that is not only technically sound, but also meaningful and user-centered.

Work Experience
Tenure involved an evolution from rapid functional prototyping (building POCs and starter code, thus, reducing time-to-market) and deep systems engineering to technical leadership roles and architectural oversight. Considered the go-to person for bringing low-level hardware emulation and proprietary communication protocols to desktop and web applications. As part of the metrics task force, designed and met code quality metrics with tools like unit tests, code sanitizers, linters and static analyzers. This career progression was formally recognized with an appointment to the first rung of TI's Technical Ladder.
