• Develop responsive and engaging user interfaces using ReactJS, translating complex requirements into intuitive and efficient front-end experiences.

• Design, implement, and optimize database schemas and queries for PostgreSQL, ensuring data integrity, performance, and scalability.

• Implement robust unit and integration tests for both backend and frontend components using Pytest (for Python) and Vitest (for ReactJS), emphasizing test-driven development (TDD) principles.

• Actively participate in architectural discussions, evaluating trade-offs for synchronous and asynchronous design patterns, and contributing to technical design decisions for cloud-native applications.

• Deploy, monitor, and troubleshoot applications within GCP environments (e.g., Cloud Run, GKE, App Engine, Cloud SQL, Secret Manager), with an understanding of multi-cloud principles including AWS.

• Contribute to the entire Software Development Life Cycle (SDLC), from requirements gathering and design to deployment, maintenance, and performance optimization, including load testing strategies.

• Collaborate closely with data scientists and machine learning engineers to integrate AI/ML models and data analytics capabilities into our applications.

• Mentor junior developers, conduct thorough code reviews, and contribute to fostering a culture of technical excellence and continuous improvement.

• Work effectively within agile methodologies, utilizing CI/CD pipelines and version control systems (e.g., Git) to ensure efficient and high-quality software delivery.

Required Skills & Qualifications:

• 5+ years of hands-on experience in full-stack or backend software development, with a strong focus on building distributed, scalable systems.

• Expert proficiency in Python, with extensive experience developing high-performance APIs using FastAPI.

• Strong experience with ReactJS for building modern, component-based user interfaces.

• Deep expertise in PostgreSQL, including database design, optimization, and advanced querying.
