What I'm looking for

I seek roles building scalable, secure web or AI-integrated systems with strong engineering practices, collaborative teams, and opportunities to design architecture and improve performance.

I am a Full Stack Engineer with hands-on experience building scalable, secure SaaS and web applications using React, Next.js, Node.js, NestJS, and Laravel. I focus on performance, maintainability, and pragmatic architecture while applying SOLID and clean-architecture principles.

At Alternate Limited and Airtel Kenya I reduced backend response times, improved platform uptime, and integrated AI agentic workflows for real-time document parsing and decision-making. I design and optimize database schemas in PostgreSQL and MongoDB, implement robust authentication (JWT, OAuth2), and maintain CI/CD pipelines with Docker and GitHub Actions.

I write comprehensive tests (Jest, Supertest, React Testing Library), produce developer-facing documentation to speed onboarding, and collaborate with cross-functional teams to deliver customer-focused features and reliable systems.
