  • API Development: Design and implement secure, well-documented RESTful APIs.
  • Mentorship & Code Quality: Lead code reviews, enforce best practices, and mentor junior and mid-level developers.
  • Cross-Functional Collaboration: Partner closely with frontend teams, product managers, and DevOps to deliver seamless end-to-end features.

    • Experience: 7+ years of professional software development experience primarily focused on backend engineering.
    • Core Java: Deep expertise in Java (Java 8/11/17+), including multithreading, concurrency, memory management, and design patterns.
    • Frameworks: Extensive experience with Spring Ecosystem (Spring Boot, Spring MVC, Spring Security, Spring Data).
    • Big Data Frameworks: Proven track record of building and tuning production-grade data pipelines using Apache Spark (Core, SQL, or Streaming).
    • Databases: Strong knowledge of relational databases (e.g., PostgreSQL, MySQL) and NoSQL solutions (e.g., MongoDB, Cassandra).
    • Tools & DevOps: Proficiency with Git, CI/CD pipelines (Jenkins, GitLab, or GitHub Actions), Maven/Gradle, and Docker.

    Nice-to-Have Skills

    • Frontend Knowledge: Familiarity or hands-on experience with Angular (TypeScript, RxJS, state management), enabling smooth full-stack collaboration.
    • Cloud Platforms: Experience deploying and managing applications on cloud environments (AWS, GCP, or Azure).
    • Container Orchestration: Knowledge of Kubernetes

    Soft Skills

    • Strong analytical, problem-solving, and debugging skills.
    • Excellent communication and collaboration skills to work effectively in an agile environment.
