KenyaWhat I'm looking for
I’m a Senior Full-Stack Software Engineer with 6+ years building scalable web, mobile, backend, and AI-integrated software systems. I’m strong across React/Angular with TypeScript, Node.js, and Python tooling like FastAPI, and I focus on moving from requirements to implementation, testing, debugging, deployment, and product iteration.
In remote engineering environments, I’ve delivered production features end-to-end—monorepo architectures, data-heavy dashboards, CI/CD, and release debugging. At Cell Collective / University of Nebraska-Lincoln, I supported a scientific modeling platform for 10,000+ users, delivered 20+ production features, and helped architect a TypeScript/Turborepo monorepo that reduced build times by 40%.
I also build practical product experiences, including AI-powered systems and mobile releases. I led development of an AI interview and candidate scoring platform (OpenAI GPT-3 workflows) and managed recruitment analytics and production deployments with AWS at EnigmaScore, and I’ve published live Android apps like Stok and Nyumba Services through my independent product work under SelfAwareTech.
