I build data warehouses that run faster and cost less, then build the AI layer on top that actually makes it to production. One client went from a $4,000 monthly bill to $40, with query times dropping from 84 hours to 2. WHO I WORK WITH ▸ Founders who need senior data work but aren't ready for a full-time hire ▸ Teams drowning in raw data across a dozen tools with no single source of truth ▸ Companies stuck past the AI demo stage, where the prototype works but nothing ships WHAT I'VE SHIPPED ▸ Migrated 250 million records from PostgreSQL to Snowflake for a B2B data platform. Monthly cost fell from $4,000 to $40, query time from 84 hours to 2. ▸ Built the dbt and Snowflake pipeline behind an influencer dashboard serving Nike, Under Armour, and New Balance. Adding New Balance lifted annual revenue by $1.8M. ▸ Rebuilt the reporting layer for a coaching platform with 100,000 users, taking dashboard refresh from 6 hours down to near real time. ▸ Scraped 10,000+ restaurant outlets across DoorDash, Uber Eats, and Grubhub at a 98%+ success rate, feeding clean order data into BigQuery. ▸ Built a knowledge graph app with multi-source OAuth ingestion, automatic document classification, and RAG querying across the whole corpus. WHAT I DELIVER Data platforms ✔ ETL and ELT pipelines (Python, SQL) ✔ Cloud data warehouses (Snowflake, BigQuery, Redshift) ✔ Data migration, data modelling, dbt transformations, Airflow orchestration ✔ Data ingestion (Fivetran, API integration) and web scraping at scale ✔ Cloud infrastructure (GCP, AWS, S3, Lambda) AI on top of your data ✔ RAG and document intelligence, where the real work is ingestion, chunking and retrieval ✔ LLM extraction pipelines turning PDFs, emails and listings into clean structured records ✔ Text to SQL and warehouse-native AI with Snowflake Cortex ✔ AI agents and MCP servers wired into your actual systems ✔ Voice agents (Vapi, LiveKit, ElevenLabs, self-hosted NVIDIA) that log every call back to your warehouse 150 contracts and $200K+ earned here, Top Rated Plus.

If your warehouse is slow, the bill keeps climbing, or an AI prototype is stuck short of production, send me two things: what you're running now and what it's costing you. I'll send back a free audit showing where the time and the money are going, and what I'd change first. Let's talk in chat.
