About

Professional summary

I am a Computer Engineer with over four years of experience in software development, backend engineering, systems integration, and process automation.

I build modern web applications using JavaScript, Java, Node.js, Express.js, Next.js, and a range of frontend frameworks. I enjoy designing scalable backend services and integrating APIs to enable reliable data migration and synchronization.

I have experience managing relational and non-relational databases, optimizing queries and data processes, and transforming data into useful dashboards and visualizations.

I also bring hands-on quality assurance and technical support experience, including manual and automated testing, test case execution, payment terminal validation, test documentation, and client support.

I use tools such as Git, GitHub, Docker, AWS, and SAP to support collaborative development, deployments, access management, and operational processes.

I am passionate about applying technology, automation, AI-driven chatbots, and data analysis to improve workflows, reduce operational overhead, and solve business challenges in collaborative teams.
