Nelson Ongiri

Hello, I’m Jan — bridging software expertise with emerging AI-driven innovation.
I'm a results-oriented software developer with a proven track record of transforming concepts into functional, impactful digital solutions. My journey started with a deep curiosity for technology and a hands-on approach to learning. Over time, that curiosity evolved into a career built on creating websites, applications, and systems that are as intuitive as they are powerful.

With expertise in Next.js, React.js and Node.js, and a strong grasp of backend development, I build solutions that balance performance, scalability, and user experience.

My technical toolkit spans JavaScript, TypeScript, Java, Python, SQL, PHP, and the venerable ‘C’, enabling me to adapt quickly to diverse project needs.

Recently, I've expanded my focus toward context engineering, prompt engineering, and AI-powered application development — blending my software background with next-generation capabilities that future-proof solutions and drive measurable results.

I thrive in environments where innovation meets problem-solving, and I'm committed to delivering value whether through team collaboration or independent projects. If you're seeking a developer who can code, innovate, and strategically adapt to the future of technology, I'm ready to contribute from day one. Let's connect and explore how I can help your team achieve its goals.
