I build production-ready data systems and backend infrastructure for companies that need their data reliable, highly queryable, and 100% automated. If your team is still manually exporting CSVs from SaaS tools every week, dealing with fragile pipelines, or struggling to scale database architecture, I design the systems that eliminate those bottlenecks. Here is how I help clients scale: █ 1. DATA ENGINEERING & WAREHOUSING I specialize in moving massive data volumes between disparate sources, databases, and warehouses while ensuring absolute data integrity, scheduling, and monitoring. • Enterprise Cloud Migration: Migrated 367M+ rows across 5 national well & gas datasets from on-prem SQL Server to Snowflake via Azure Data Factory (including year-based partitioning for 275M+ row tables) with zero data loss. • Custom Pipeline Development: Developed a Python pipeline converting ESRI Geodatabase files to GeoParquet, loading 96 spatial layers into Snowflake using native GEOGRAPHY columns. • Database Architecture: Built a regulatory database covering 354 interstate pipeline operators and 275K fact rows (2011–2025). • Multi-Source Warehousing: Engineered an Azure-provisioned (Terraform/Docker) PostgreSQL warehouse consolidating NetSuite (SuiteQL) and SharePoint (Graph API) data to feed daily operational PowerBI dashboards. • Financial Syncs: Automated a 68-entity QuickBooks Online + Turvo TMS synchronization into PostgreSQL with secure OAuth2 authentication and scheduled refreshes. • Automated Ingestion: Set up a T-1 Crude Oil database managing 6+ OCR Excel layouts with robust deduplication logic and automated GIS enrichment. █ 2. BACKEND SYSTEMS & CUSTOM INTEGRATIONS I engineer API-heavy backends and third-party integrations where data reliability and complex business logic cannot afford to fail. • AI-Driven Automation: Built an AI applicant review system processing ~300 forms/day using 26 deterministic rules combined with LLM edge-case handling, featuring custom forms, SSO, and a two-way HubSpot sync. • E-Commerce Infrastructure: Developed a high-performance custom product builder utilizing Next.js 15 App Router, Express, Prisma, and PostgreSQL, optimized with GA4 e-commerce tracking and JSON-LD for SEO. • Marketplace Integrations: Built an Amazon Selling Partner API integration for order/inventory sync, settlement reconciliation, and 7 custom Streamlit analytics reports. ──────────────────────────────────────── TECHNICAL PROFICIENCIES • Cloud & Infra: Azure (Data Factory, Functions, Blob, SQL), AWS (Lambda, RDS), Terraform, Docker, PM2 • Databases & Warehouses: Snowflake, PostgreSQL, SQL Server, MySQL, MariaDB • Data/ETL Stack: Python, pandas, geopandas, pyarrow, openpyxl, GeoParquet, Databricks • Backend & Languages: Node.js, TypeScript, FastAPI, Flask, Bun, Prisma, SQLAlchemy, T-SQL, PL/pgSQL • Core Integrations: NetSuite, QuickBooks, Amazon SP-API, Microsoft Graph, HubSpot, Turvo, ESRI GDB • AI Orchestration: OpenAI API, Pydantic, Instructor ──────────────────────────────────────── HOW WE WILL WORK TOGETHER I operate as a consultative partner, not just a task-taker. I ask deep structural questions before writing a single line of code to catch architectural flaws early. You will receive proactive progress updates before you ever have to ask for them. Every system I deliver features comprehensive error handling, logging, and monitoring built-in from day one. If you have a complex data pipeline, a broken integration, or a backend system that needs to scale, send me a brief message outlining your current setup. I will give you a clear, objective analysis of the best path forward. barumkhan.dev
