Hands‑on experience with AWS (Lambda, ECS, DynamoDB, SQS/SNS, API Gateway, Step Functions, etc.) and strong understanding of cloud‑native patterns. Exposure to GCP, Azure, or other Cloud Platforms would be a valuable plus. Solid experience with Infrastructure as Code (Terraform preferred), CI/CD pipelines, and modern deployment practices.

Experience building AI-enabled systems (including LLM- or RAG-based solutions) from MVP or proof-of-concept through to production-ready implementations, with consideration for reliability, evaluation, security, and maintainability. Understands where AI meaningfully enhances backend systems (e.g., classification, summarisation, anomaly detection) versus where traditional algorithms are more appropriate. Able to evaluate risk, cost, scalability, and maintainability when proposing AI‑driven solutions. Curious about emerging AI patterns, frameworks, and tooling, with the ability to apply them pragmatically in line with client needs. Comfortable advising clients on realistic AI opportunities and helping them navigate hype vs. practical value.
• Consulting & Client Delivery: Experience working in a consulting or client-facing environment, comfortable operating in ambiguous problem spaces and contributing to both solution discovery and delivery.
