Project Description
AI/ML for Observability (AIOps)
Developed machine learning and deep learning solutions for observability data to enhance IT operations. Implemented time series forecasting, anomaly detection, and event correlation models. Integrated LLMs using prompt engineering, fine-tuning, and RAG for incident summarization. Built MCP client-server architecture for seamless integration with the Grafana ecosystem.
Duties/Day to Day Overview
Machine Learning & Model Development
• Design and develop ML/DL models for:
• Time series forecasting (e.g., system load, CPU/memory usage)
• Anomaly detection in logs, metrics, or traces
• Event classification and correlation to reduce alert noise
• Select, train, and tune models using frameworks like TensorFlow, PyTorch, or scikit-learn
• Evaluate model performance using metrics like precision, recall, F1-score, and AUC
ML Pipeline Engineering
• Build scalable data pipelines for training and inference (batch or streaming)
• Preprocess large observability datasets from tools like Prometheus, Kafka, or BigQuery
• Deploy models using cloud-native services (e.g., GCP Vertex AI, Azure ML, Docker/Kubernetes)
• Maintain retraining pipelines and monitor for model drift
LLM Integration for Observability Intelligence
• Implement LLM-based workflows for summarizing incidents or logs
• Develop and refine prompts for GPT, LLaMA, or other large language models
• Integrate Retrieval-Augmented Generation (RAG) with vector databases (e.g., FAISS, Pinecone)
• Control latency, hallucinations, and cost in production LLM pipelines
Grafana & MCP Ecosystem Integration
• Build or extend MCP client/server components for Grafana
• Surface ML model outputs (e.g., anomaly scores, predictions) in observability dashboards
• Collaborate with observability engineers to integrate ML insights into existing monitoring tools
Collaboration & Agile Delivery
• Participate in daily stand-ups, sprint planning, and retrospectives
• Collaborate with:
• Data engineers on pipeline performance and data ingestion
• Frontend developers for real-time data visualizations
• SRE and DevOps teams for alert tuning and feedback loop integration
• Translate model outputs into actionable insights for platform teams
Testing, Documentation & Version Control
• Write unit, integration, and regression tests for ML code and pipelines
• Maintain documentation on models, data sources, assumptions, and APIs
• Use Git, CI/CD pipelines, and model versioning tools (e.g., MLflow, DVC)
