Perform hyperparameter tuning using tools like Optuna, Ray Tune, or built-in frameworks.

Evaluate model performance using appropriate metrics (AUC, F1, MAE, BLEU, WER, etc.).

2. Data Engineering & Processing

Work with structured and unstructured data (text, images, audio, logs, documents).

Build data pipelines using Python, SQL, Spark, Airflow, or similar.

Apply data quality checks, deduplication, anomaly detection, and data validation (Great Expectations, pydantic).

3. ML Deployment & MLOps

Deploy models as APIs using FastAPI, Flask, Node, or cloud-native tools.

Implement CI / CD pipelines for ML (GitHub Actions, GitLab, Jenkins).

Use containerization & orchestration (Docker, Kubernetes).

Manage models using MLflow, Vertex AI, SageMaker, Azure ML, or Databricks.

Implement automated retraining, model versioning, rollback, and monitoring.

Handle inference optimizations (quantization, batching, caching).

4. LLM & GenAI (Preferred but not mandatory)

Work with foundation models like GPT, LLaMA, Claude, Mistral, etc.

Build RAG pipelines with vector databases (Qdrant, Pinecone, FAISS, Elasticsearch).

Prompt engineering and evaluation.

Optimize embeddings, context windows, and chunking strategies.

Integrate LLMs into production APIs and workflows.

5. Cloud & Infrastructure

Experience with at least one cloud provider (AWS, Azure, GCP).

Use managed ML services like :

AWS : SageMaker, Lambda, Textract, Comprehend

Azure : AI Foundry, Functions, Search

GCP : Vertex AI, Cloud Run

Manage GPU / CPU compute workloads efficiently.

6. Software Engineering Best Practices

Write clean, modular, well-tested Python code.

Maintain repositories adhering to branching, versioning, and code review standards.

Use design patterns for scalable ML pipelines.

Build internal tools for automation, testing, and monitoring.

7. Cross-functional Collaboration

Work closely with product managers, data engineers, backend engineers, and business analysts.

Translate business problems into ML solutions with measurable ROI.

Document technical designs, APIs, models, architecture diagrams.

8. Monitoring, Observability & Optimization

Implement model monitoring for data drift, concept drift, performance degradation.

Evaluate model reliability, bias, fairness.

Implement logging & metrics (Prometheus, Grafana, ELK).

Continuously improve model performance and resource usage.
