Full Stack Engineer

I spearheaded the end-to-end design, development, and deployment of secure, scalable web and mobile applications for enterprise clients across the education, real estate, and governance sectors. I engineered Mada Scheme Genius, an AI-powered education SaaS platform, successfully integrating Google Gemini AI pipelines with bulk processing, rate limiting, and organization-level data isolation. I designed and deployed the KejaYangu real estate marketplace, where I architected a scalable microservices architecture utilizing Redis caching, WebSockets for real-time chat, and secure webhook validation for M-Pesa and Stripe payment APIs. I enforced rigid security best practices across all client ecosystems, implementing strict Role-Based Access Control (RBAC), JWT access/refresh token rotation, and immutable audit logging systems. I translated complex business and regulatory requirements into production-ready software solutions while mentoring junior contributors on codebase design patterns, optimization, and documentation.

I designed, built, and deployed a cross-platform mobile application that was successfully published on the Google Play Store, managing the full lifecycle from initial wireframing to production release. I engineered responsive web interfaces and internal administrative dashboards directly from Figma designs, ensuring strict adherence to UI/UX specifications and performance optimization guidelines. I built secure, data-driven platforms handling complex business metrics, asynchronous background tasks, and high-volume transactions. I integrated third-party RESTful APIs, device-native features (such as geolocation tracking and push notifications), and secure payment processing services. I planned and executed rigorous end-to-end testing, validation, and automated QA pipelines to ensure application stability across diverse Android device configurations before rolling out production updates. I contributed to CI/CD pipeline improvements, containerization workflows, and deployment processes to increase infrastructure reliability and minimize system downtime.
