Data Engineering

Data Infrastructure for the
AI Era.

We build the data pipelines, vector stores, and real-time streaming infrastructure that powers modern AI applications and business intelligence.

Discuss Your Data

Vector Database Architecture

Design and deploy production-grade vector stores using Pinecone, Weaviate, or ChromaDB for semantic search, recommendation engines, and RAG pipelines.

Real-Time Streaming

Event-driven architectures using Kafka, Redis Streams, and WebSockets for real-time data processing, notifications, and live dashboards.

Data Warehouse & ETL

Modern data warehouse solutions with Snowflake or BigQuery, orchestrated with dbt for reliable, tested, and documented data transformations.

Deep Dive

The AI Data Stack: RAG Pipelines

Retrieval-Augmented Generation is the most impactful AI architecture pattern today. We build production-grade RAG systems that connect your proprietary data to LLMs.

  • 1

    Ingestion & Chunking

    Documents, PDFs, and databases are parsed, chunked, and cleaned with metadata tagging for optimal retrieval.

  • 2

    Embedding & Indexing

    Text chunks are converted to vector embeddings using OpenAI or open-source models and stored in high-performance vector databases.

  • 3

    Retrieval & Generation

    Semantic search retrieves the most relevant context, which is injected into LLM prompts for accurate, grounded responses.

vector_store.py

import pinecone

from langchain.vectorstores import Pinecone

# Semantic Search

query = "Q3 Revenue analysis"

docs = index.similarity_search(

query,

k=5, # Top 5 matches

filter={ "department": "finance" }

)

# Pass to LLM

llm.predict(prompt, context=docs)
