Hire an AI & ML engineer to ship production systems
Work directly with AI & ML Engineer Shashi Ranjan — not an agency layer — on machine learning pipelines,
agentic systems, hybrid RAG, LLM fine-tuning, and production LLMOps built for real business workloads.
Design and build production AI systems: assistants, agents, RAG apps, fine-tuned models, and ML APIs for startups and enterprises.
Architecture and build for LLM apps, agents, and ML services
Integration with OpenAI, Anthropic, Hugging Face, Bedrock, or self-hosted models
Backend APIs with FastAPI, Docker, and cloud deployment on AWS
Evaluation, guardrails, and monitoring so systems stay reliable after launch
PythonLangChainFastAPIAWSRAGAgents
Agentic AI Systems
Production AI agents with tools, memory, and control
Autonomous LLM agents that call tools, follow multi-step plans, and run securely — including MCP integrations, LangGraph workflows, and SmolAgent systems.
Tool-using agents with MCP, APIs, databases, and internal systems
LangGraph / LangChain orchestration and structured outputs
Locally hosted or cloud agent runtimes for sensitive data
Guardrails, logging, and regression checks for agent reliability

RAG & Retrieval
Production RAG systems connected to your data
Retrieval-augmented generation from docs, ERP, PostgreSQL, or MongoDB — with hybrid search, embeddings, vector databases, and reranking.
Hybrid BM25 + dense retrieval and chunking strategies
Qdrant / pgvector indexes with Cohere or cross-encoder rerank
Redis caching and low-latency query paths
CRAG-style corrective loops and evaluation with Ragas-style metrics

LLM Fine-Tuning
Domain-ready models with LoRA / QLoRA
Fine-tune open-source LLMs for your tone, domain, and tasks — efficient PEFT workflows on Hugging Face with evaluation, export, and deployment support.
Dataset prep, cleaning, and instruction formatting
LoRA / QLoRA / PEFT training for Mistral, Llama, and similar models
Preference-style alignment workflows where needed
ONNX / quantized export paths for faster inference

ML Engineering
Reliable ML systems from data to inference
Shashi Ranjan is an ML Engineer as well as an AI engineer — delivering classical and deep learning systems
for classification, regression, forecasting, ranking, and recommendation, with production-grade training, registry, and monitoring.
Feature engineering and tabular ML (XGBoost, LightGBM, Scikit-Learn, PyTorch)
Model development: ANNs, gradient boosting, Optuna hyperparameter search, offline evaluation
Training pipelines with Airflow, Spark, Kafka, and Ray where needed
MLflow model registry, continuous training, and A/B rollout patterns
Drift monitoring and batch or online inference services
Analytics & decision systems — dashboards, SQL automation, and client ML delivery from consulting work
