I will be your backend developer, website developer, software engineer
Alex Kuzma
About this gig
I am a backend developer, website developer, and software engineer who designs, builds, and scales systems that power real businesses.
I create high-performance backends and full-stack applications for businesses that demand reliability, scalability, and long-term value.
With years of experience delivering production-grade systems for startups and established companies, I provide senior-level engineering from architecture to deployment, helping teams move faster with confidence.
What I deliver:
- Scalable backend systems (Node.js, TypeScript, JavaScript, PHP)
- Scalable frontend systems (Next.js, React.js)
- Secure REST or GraphQL APIs
- Full-featured web apps with authentication, payments, and integrations
- CI/CD pipelines and production deployment
- Documentation, handover, and post-launch support
You'll get clean architecture, maintainable code, and infrastructure built to scale the quality of an in-house senior engineer without the overhead.
If your project needs to be fast, secure, and built to last, lets connect and map out the best path to make it happen.

Yes, I offer optional monthly maintenance and update packages to ensure ongoing stability, performance monitoring, and feature enhancements.

What if I’m not technical?
No problem. I’ll guide you through every step, explain everything in plain language, and make sure you fully understand your system before handoff.
