Freelance Data Engineering Developer - Philip Warkentien II
Freelance Data Engineering Developer5.0 (1 reviews)

### About me I’m a **Staff-level Frontend and UI Engineer** with **13+ years of combined professional and teaching experience**, specializing in **UI engineering**: Design Systems, enterprise CSS, responsive layouts, accessibility (WCAG), data visualization, and web animations — with deep expertise in **React, JavaScript/TypeScript, HTML, and CSS**. Throughout my career, I’ve consistently operated as **the bridge between Design and Engineering**, translating ambitious visual and UX goals into **scalable, performant, and accessible frontend systems**. My work focuses on aligning design intent with real-world engineering constraints while maintaining long-term maintainability and code quality. I’ve led and contributed to **Design System initiatives**, built **data-visualization–heavy charts, tables, and UIs**, improved **localization workflows**, and helped raise **UI standards across critical user flows** in large, high-impact products. A recurring part of my work involves **untangling legacy stylesheets** and transforming them into **clean, enterprise-grade CSS and component architectures**. In addition to hands-on engineering, I bring **5.5 years of experience as a Udacity mentor**, where I guided developers through frontend, UI, and JavaScript projects, reviewed real-world codebases, and helped engineers progress from fundamentals to **production-ready practices**. I mentor because I enjoy helping developers move beyond surface-level fixes and truly understand **why UI breaks** — whether it’s layout mechanics, rendering behavior, accessibility pitfalls, or component design.

I build software solutions for aerospace and robotics industry ranging from building high fidelity dynamics engine software for mars and lunar landing, docking of satellites to deployment of robotic manipulators in space to building software tools for cyber physical systems ranging from rovers, leg-based robots to aerial vehicles e.g. coaxial helicopters and drones with experience in both low level and high level design. I am also a mentor and I love programming and I love teaching especially programming with C/C++ and Python, Design patterns, Data structures and Algorithms. I love taking on new problems and help solving the problems through systematic approach which is scalable in nature. Through mentoring, I get the opportunity to accelerate my own learning curve by constantly challenging my self with problems from different domains and keep myself up to date with current trends in software design. I believe the best way I can contribute to a better society by sharing my knowledge to others and hope they can build upon that. I always find programming to be much more than learning syntax of a language, its more of an art. Give me an opportunity and I will teach you the art of producing high quality functional codes
