• Backend Technologies: Proficiency in building backend services and APIs using Node.js/TypeScript (NestJS) and/or Python (FastAPI, Django/Flask). 
• System Design: Experience designing scalable, resilient services (service boundaries, data modeling, caching, messaging, observability, and performance considerations). 
• Software Design: Strong knowledge and hands-on use of SOLID principles, common design patterns, and clean code practices. 
• DDD (Domain-Driven Design): Experience applying DDD concepts (bounded contexts, aggregates, entities/value objects, domain events) to structure complex systems. 
• API Design: Strong understanding of REST API design (resource modeling, versioning, pagination, error handling, idempotency, and documentation). 
• Authentication & Security: Experience with OAuth2/OpenID Connect, Identity Providers (IdP) concepts, and basic cryptography concepts (hashing, encryption, signing, key management) applied in software. 
• Cloud: Experience deploying applications on AWS (e.g., compute, networking, storage, IAM) and working with cloud-native patterns. 
• CI/CD: Hands-on experience building and maintaining CI/CD pipelines (build, test, security checks, deploy) and release processes. 
• Testing: Solid knowledge of unit testing (test design, mocking, coverage) and experience with automated testing practices. 
• Software Engineering Good Practices: Code reviews, refactoring, documentation, observability, and collaboration in an Agile environment.
• Frontend Technologies: Expertise in modern frontend frameworks, such as React, Angular, Typescript, or Vue.js. Strong HTML, CSS, and JavaScript skills. 
• Database: Experience with relational and non-relational databases (e.g., MySQL, PostgreSQL, MongoDB). 

Nice to have: 

• Deeper experience with Machine Learning, neural networks, prompt engineering, and LLM fine-tuning/training and deployment. 
• AI Engineering Basics: Familiarity with LLM fundamentals, prompt engineering, embeddings/vector search, and integrating AI capabilities into applications. 
• Version Control: Proficient in Git for version control and collaborative development. 
• DevOps: Familiarity with cloud platforms (Azure, AWS, and GCP) and experience with containerization (Docker) and orchestration (Kubernetes) is a plus.
