About Zaiba

Senior full-stack developer with 4+ years of experience delivering scalable, enterprise-grade web applications for global organizations such as Oracle and PwC. I specialize in building modern user interfaces with React and robust backend systems using Java (Spring), Scala, and Node.js, with a strong focus on clean architecture, performance, and maintainability.
I have hands-on experience developing customer-facing portals, internal dashboards, and automation tools, as well as designing and consuming RESTful APIs for data-driven applications. I’m comfortable working in complex environments where code quality, security, and documentation matter, and I actively contribute to improving development workflows through CI/CD, testing practices, and clear technical documentation.
Having worked closely with product managers, designers, and QA engineers, I understand how to translate business requirements into reliable technical solutions. I’m equally effective joining an existing team or working independently to deliver well-structured, production-ready features.
Clients value my analytical mindset, clear communication, and ability to quickly understand new domains, making me a reliable partner for both short-term tasks and long-term projects.
