I'm Hemstone Omollo, a Senior Full-Stack Software Engineer with over 8 years of experience building scalable web applications, SaaS platforms, and AI-powered business systems.I'm the founder of Voltageitlabs, a software development agency based in Nairobi, Kenya, helping startups and businesses transform ideas into reliable digital products.
I build products end-to-end—from designing intuitive user interfaces with Nuxt.js, Tailwind CSS, and Figma to developing secure, high-performance backend services using Django, Django Ninja, Django REST Framework, PostgreSQL, Redis, and Celery. I also manage cloud deployment, CI/CD, API integrations, and long-term product scalability.
My experience includes developing multi-tenant SaaS platforms, workflow automation systems, payment integrations, AI-powered applications, and custom business software. I enjoy architecting systems that are maintainable, API-first, and ready to support future web, desktop, and mobile applications without requiring major rewrites.
I hold a Bachelor of Science in Mathematics and Computer Science from Kenyatta University (2024). Whether working independently or collaborating with a team, my focus is on building software that is fast, scalable, and delivers measurable value to users and businesses.
