• A passion for solving complex software challenges, especially those involving AI and large-scale microservice architectures.
• Expertise in API design, integration, and optimization, particularly when interacting with machine learning models (including LLMs) and external services.
• Knowledge of object-oriented programming (OOP) and experience in creating software thats extensible, reusable, and maintainable.
• Strong problem-solving skills, with the ability to prioritize and drive multiple complex projects simultaneously.
• Up-to-date knowledge of industry trends, particularly in AI/ML, and a passion for learning and adapting quickly.

Experience Requirements:

• Minimum 3 years of experience with Node.js, including developing back-end microservices at scale.
• At least 2 years of experience working with APIs, specifically integrating AI services or interacting with large language models (e.g., GPT, BERT).
• At least 2 years of experience with NoSQL databases like Cassandra, as well as search technologies like ElasticSearch and caching solutions like Redis or Memcached.
• Minimum 1 year of experience with languages like Python, Perl, or shell scripting, especially in automation or AI-related tasks.
• Experience with full-stack development and collaborating across distributed teams.
• Prior experience with agile software development methodologies and full lifecycle software development.
• Bachelors degree in Computer Science, MIS, or a related discipline, or equivalent hands-on experience.
• Strong track record of completing projects on time and delivering high-quality solutions.

Bonus Skills:

• Experience deploying machine learning models to production, with a deep understanding of the challenges of scaling AI systems.
• Familiarity with PHP or similar technologies.
• Hands-on experience with MLOps tools and frameworks, or AI model serving platforms (e.g., TensorFlow Serving, PyTorch Serve).
