Saurabh Sharma *Data & AI Developer/Architect* 📍 Goa, India Overview: While my deepest expertise lies in the systems that process, store, and serve data, I have extensive hands-on experience managing the entire stack, including React and modern UI frameworks. I breathe data, but I also understand how to build and connect the interfaces that make that data useful to end users. I can own a project end-to-end, but I excel at architecting the heavy-lifting backend systems that make those frontends successful. To put it simply, I love data tier challenges. I have a deep, intuitive understanding of the Modern Data Stack and how to make it work reliably in production. Whether you need to build a data platform from scratch, integrate LLMs, or need strategic DevOps consulting to fix your cloud infrastructure, I bring enterprise-grade experience to every project. ### What I Can Help You Build: Data Engineering & The Modern Data Stack I build and optimize ELT/ETL pipelines and data architectures from ingestion to transformation. * Ingestion & Orchestration: Airbyte, Singer, Stitch, Airflow. * Transformation: dbt, Spark, Pandas, PySpark, SQL. * High-Performance Compute: Deep practical experience with DuckDB, Apache Arrow, Parquet, Daft, and Dask for fast batch and real-time processing. * Cloud Data Platforms: Data lakes (S3), warehouses (Redshift, BigQuery), and streaming (Kinesis) on AWS and GCP. GenAI & Vector Infrastructure I build the backend plumbing for AI applications so they actually work in production. * Setting up RAG (Retrieval-Augmented Generation) pipelines. * Integrating LLMs and managing vector databases (Pinecone, pgvector, Weaviate) for low-latency semantic search. Full-Stack & UI Development I have a strong background in shipping end-to-end applications. When a project requires it, I can build and maintain the frontend to ensure it integrates cleanly with the backend. Building responsive, data-heavy interfaces using React and modern UI component libraries. Developing robust backend APIs (Node.js, Python) to serve frontend applications efficiently. Bridging the gap between data engineering and user experience, ensuring dashboards and applications are fast and reliable. DevOps Consulting & Cloud Architecture Beyond writing code, I consult on infrastructure maturity. I help teams optimize cloud spend, establish SRE practices, and automate workflows. * Infrastructure as Code (Terraform, Serverless Framework). * CI/CD pipelines (GitHub Actions) and container orchestration (Docker, ECS, Nomad). * Administering high-availability PostgreSQL clusters and distributed systems with automated failover. Trading & Real-Time Systems * Backend systems for crypto and equity trading, including real-time market data ingestion and low-latency risk engines. ### How I Work: * AI-Augmented Coding: I use Claude and Gemini daily as part of my actual coding workflow. They act as my pair-programmers, helping me write test-driven, well-documented code and catch edge cases early. For you, this means higher quality code and faster turnaround times without sacrificing reliability. * Proactive Reliability: I don't wait for things to break. I set up monitoring, alerting, and runbooks upfront. * Clean Code & Ownership: I write clean, maintainable Python and Node.js. I treat my clients' infrastructure with the same care I treat my own, and I focus on building systems that are easy to maintain long after the initial build. ### Core Tech Stack: Data: Airflow, dbt, Spark, DuckDB, Parquet, Arrow, Daft, Dask, Airbyte, Singer, Stitch, Pandas, Polars, PySpark. AI/Vector: Pinecone, pgvector, Weaviate, RAG, LLM Integration. Cloud/DevOps: AWS, GCP, Terraform, Docker, Kubernetes/ECS, GitHub Actions, PostgreSQL.
