I'm Samuel Kamau Kang'ethe — a full-stack software engineer and the technical lead behind Rapid Tech Solutions. I specialize in building end-to-end applications that prioritize performance, clean architecture, and seamless user experiences.
Whether it's integrating advanced AI capabilities, deploying fully monetized mobile applications, or architecting robust back-end APIs, I bring an optimization-first approach to every project. I care deeply about how systems run under the hood, ensuring that every product I ship is as fast, efficient, and low-latency as it is visually compelling.
End-to-end web solutions — from responsive front-ends with modern JavaScript frameworks to robust PHP/MySQL back-end systems, APIs, and database architecture.
Native and cross-platform mobile applications built for performance and usability — from concept and prototyping through to deployment on iOS and Android.
User-centered interfaces and visual identities — wireframes, prototypes, brand systems, and print-ready assets crafted in Figma, Illustrator, and Photoshop.
Professional video production and post-production — motion graphics, color grading, and storytelling for brands, social media, and promotional content.
