Leverage AI-assisted development tools as a standard part of day-to-day engineering practice.

Direct Responsibilities

    Develop scalable full-stack solutions using Java, Spring Boot, and modern frontend frameworks (React/Angular).

    Design and optimize high-performance APIs with security, caching, and fault tolerance.

    Develop robust backend services with efficient database interactions.

    Build responsive UI with seamless backend integration.

    Automate CI/CD pipelines for rapid, reliable software delivery.

    Lead cloud-native deployments with containerization, auto-scaling, and cost optimization.

    Enforce Quality-first engineering: Unit, integration, and ensure high code quality with SonarQube.

    Mentor junior developers, conduct code reviews, and drive technical excellence across the team.

    Collaborate with stakeholders to translate business needs into scalable technical solutions.

Contributing Responsibilities

    Contribute to technical design discussions and architecture decisions, particularly around API design, data layer, and system integration
