- API Management: Design and implement RESTful and GraphQL APIs to support web and mobile frontends.
- Database Management: Optimize database schemas and complex queries for both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB, Redis) systems.
- Microservices Architecture: Develop and orchestrate microservices, ensuring efficient inter-service communication and data consistency.
- Security & Compliance: Implement secure authentication/authorization protocols (OAuth2, JWT) and ensure data protection across all layers.
- Testing & Quality: Write comprehensive unit, integration, and end-to-end tests using frameworks like JUnit (Java) and pytest (Python).
- Performance Optimization: Identify and resolve bottlenecks in application logic, database access, and network latency.
- Collaboration: Participate in Agile ceremonies, perform code reviews, and contribute to technical documentation.
Technical Skills & Qualifications Core Programming
- Java: Proficiency in Java 17+ with deep knowledge of the Spring Ecosystem (Spring Boot, Spring Security, Spring Data).
- Python: Expert-level Python 3.x skills, with experience in frameworks like FastAPI, Django, or Flask.
Databases & Storage
- Experience with relational databases (PostgreSQL, MySQL) and NoSQL solutions (MongoDB, Redis, Cassandra).
- Strong understanding of ORM tools like Hibernate (Java) and SQLAlchemy/Django ORM (Python).
Infrastructure & Tools
- Containerization: Hands-on experience with Docker and Kubernetes.
- Cloud Platforms: Familiarity with AWS, GCP, or Azure services (Lambda, EC2, S3, RDS).
- CI/CD: Proficiency with Git and automated deployment pipelines (GitHub Actions, Jenkins, or GitLab CI).
- Messaging: Experience with message brokers like Apache Kafka or RabbitMQ for asynchronous processing.
Soft Skills
- Strong analytical and problem-solving mindset.
- Ability to translate complex business requirements into technical specifications.
- Excellent communication skills for cross-functional collaboration.
