Design, develop, and support enterprise applications, APIs, and platform services.
Modernize legacy systems through adoption of contemporary frameworks, architectures, and engineering practices.
Develop integrations between internal systems and enterprise platforms.
Contribute to proof-of-concept initiatives and evaluation of emerging technologies.

DevOps & Automation

Build and enhance CI/CD pipelines to improve software quality and delivery efficiency.
Automate testing, deployment, compliance, and operational processes.
Support containerized and cloud-ready application architectures.

Experience working with relational databases such as PostgreSQL, Oracle, or SQL Server.

Modern Engineering Practices
