Solomon Nnajieze | Software & DevOps Engineer

About Me

I'm a Software Engineer who evolved into DevOps and Platform Engineering. Starting with PHP and Laravel, I've spent the last 7 years building, deploying, and scaling web applications in production environments.

My journey took me from pure backend development to owning systems end-to-end—application code, infrastructure, CI/CD pipelines, and operational reliability. I've worked with teams at SAMBA-DATA R&D, SwitchCoins Global, BFA Digital Tech, and various startups, handling everything from architecting REST APIs to managing cloud deployments on AWS and DigitalOcean.

What drives me: reducing operational friction, automating repetitive tasks, writing clear documentation, and helping teams move faster with confidence. I believe great engineering is invisible—it just works.

When I'm not coding, I'm writing technical guides, mentoring junior developers, or exploring new infrastructure tooling. I'm open to remote-first roles with teams focused on reliability, automation, and real-world impact.
