Nice To Haves

Advanced proficiency in C++, C#, and Python, with deep knowledge of object-oriented design, design patterns, concurrency, and memory management.
Proven experience designing, implementing, and maintaining RESTful APIs and microservices, including secure authentication/authorization (OAuth, JWT) and efficient inter-service communication (gRPC, message queues).
Strong command of AWS services such as Lambda, EC2, S3, RDS, DynamoDB, SageMaker, and CloudFormation; familiarity with infrastructure-as-code tools like Terraform or CloudFormation for automated, repeatable deployments.
Skilled in developing, training, fine-tuning, and deploying machine learning models, Generative AI, and Large Language Models (LLMs) using PyTorch, with hands-on experience in model lifecycle management and deployment automation.
Expertise in relational (PostgreSQL, MySQL) and NoSQL (DynamoDB, InfluxDB) databases, including schema design, indexing, replication, and performance tuning.
Experienced in building and maintaining CI/CD pipelines using Jenkins, GitHub Actions, GitLab CI, with strong skills in automated testing, container builds, and deployment automation.
Working knowledge of Docker and Kubernetes, including deployment manifests, Helm charts, and cluster management best practices.
Proficient with Git workflows (branching, pull requests, code reviews) and collaborative development in distributed teams.
Deep understanding of secure coding principles, identity and access management (IAM), encryption standards (TLS/SSL), and vulnerability mitigation.
Experience deploying applications within regulated environments, ensuring compliance with ISO 27001, NIST, GDPR, or equivalent frameworks.
Skilled in conducting security audits, vulnerability assessments, and implementing remediation strategies.
Solid knowledge of Agile methodologies (Scrum, Kanban) and software development lifecycle (SDLC) processes.
Familiarity with HTML5, CSS3, and modern JavaScript frameworks (React, Angular, Vue.js) for HMI customization is advantageous.
