Hands-on experience with cloud platforms, preferably AWS (e.g. Lambda, SQS, DynamoDB, ECS/EKS)
Good understanding of modern web architecture (micro frontends, SPAs, CDNs, caching)

Additional Assets:

Experience working with generative AI APIs (OpenAI, Claude, Mistral, 11-Labs etc.)
Exposure to Prompt Engineering, retrieval-augmented generation (RAG) and agentic workflows
Understanding of Vector Databases (e.g. Pinecone, Weaviate, FAISS)
Coding with AI (e.g. GITHub Copilot, Cursor)
Familiarity with low-code/no-code tools (e.g. n8n, Make, Zapier)
