Most data pipelines don’t fail because of code. They fail because they weren't built for scale. With 8+ years of experience engineering data systems at companies like Microsoft and Coreweave, I help businesses move away from "brittle prototypes" to production-grade, scalable infrastructure. I don’t just move data; I build the "Source of Truth" that leadership and AI systems actually trust. 💬What I Solve for You: Productionizing AI Pipelines: Hardening Python prototypes into scalable RAG and LLM infrastructures (AWS/Azure). ➔Infrastructure-as-Code: Building automated, modular ETL/ELT pipelines that don't require daily manual fixes. ➔The "One-Source" Dashboard: Integrating messy data from APIs, SaaS (Shopify, HubSpot), and DBs into clean Snowflake/BigQuery layers. ➔Performance Recovery: Optimizing slow SQL queries and high-cost cloud warehouses to save you thousands in monthly spend. 🛠 Tech Stack: Languages: Python (FastAPI, Pandas, PySpark), SQL Cloud & Warehousing: AWS (Glue, Lambda, S3), Snowflake, BigQuery, Azure Orchestration: Airflow, dbt, GitHub Actions Data Ops: API Integrations, Vector DBs, Data Validation ✅ Why Me? 8+ Years Experience: I’ve seen what breaks at the enterprise level and how to prevent it in your startup. Speed over Perfection: I focus on shipping high-impact systems that drive revenue, not just technical documentation. Transparent Communication: You get regular updates and a partner who challenges requirements to find better solutions.

I build BigQuery warehouses, dashboards, and increasingly the AI and LLM layer that goes on top of them. For the last six years I've consulted for companies ranging from big-box retailers to Y-Combinator tech startups to help them get out from under manual reporting and scattered data. Most recently I've been building RAG systems and LLM observability for industrial SaaS applications, alongside the BigQuery, executive dashboards, and data engineering work (ETL) that has been my main lane for years. What I help clients build: • RAG and LLM systems. Production RAG over your business data (Claude, Gemini, GPT, vector stores), prompt and retrieval evaluation, dashboards for LLM cost, latency, and accuracy, and agentic workflows that connect tools to action. • BigQuery warehouses and ETL. Schema design, partitioning, cost cleanup, plus Python pipelines that ingest from Quickbooks, Stripe, GHL, HubSpot, GA4, Shopify, Filevine, and a long list of custom APIs. HIPAA-compliant when it needs to be. • Dashboards that actually get used. Looker Studio, Metabase, and ThoughtSpot (avoid PowerBI and Tableau like the plague). I always prototype the dashboard, so you see the end result first, we don't build pipelines you don't need, and I can give you a fixed-price quote (most freelancers will never give fixed-price quotes). • Internal tools and automations. Cloud Functions, Cloud Run, Slack and email integrations, Stripe billing, scheduled syncs. Things that should just run quietly in the background and stop being someone's manual job. A few things to know about working with me: I've hired freelancers on Upwork myself, so I know the difference between someone who hides behind their service and someone who moves the business forward. I write SQL and Python the next engineer can read without a guide. I'll tell you when the fancy version of a thing isn't worth building. I prefer working off real data and screenshots over abstract requirements docs. I have adopted AI tools that help me to complete data projects in 7 days by myself that used to take me 12 weeks with a small team.

I deploy proactive AI automation that doesn't just answer, it acts. Unlike a chatbot, an OpenClaw setup monitors your email, calendar, Slack, CRM, and task tools 24/7, executes multi-step workflows, and routes ambiguous cases to a human. I cut operational costs up to 40% by turning brittle data and manual ops into measurable AI systems and executive-ready KPI dashboards that survive real usage. OpenClaw / AI Agents & Workflow Automation: • Deploy OpenClaw assistants on hardened VPS with SSL, automated backups, and least-privilege Docker, accessible 24/7 with zero command-line use. • Build proactive workflows: smart scheduling, email triage, RAG document Q&A, daily briefings, KPI report automation, customer case monitoring with scenario routing, and cron-scheduled automation, all with human-in-the-loop on destructive actions and full audit trails. • Automated 40% of support inquiries via AI chatbot development on the OpenAI API; AI agent monitoring saves $150K+ annually. LLM Ops, Analytics & Data Engineering: • CI/CD for AI development with automated rollbacks reduced post-deploy incidents by 50%; • OpenClaw-based canary scoring catches quality drops before rollout. • C-suite KPI dashboards in Microsoft Power BI and Looker Studio improved decision speed 3x; cut manual reporting time 80% via Python automation of Excel and Google Sheets. • Marketing analytics & attribution: improved attribution accuracy 45% via Google Tag Manager and API-driven pipelines; Python sales forecasting lifted projection accuracy 12%. • ETL pipeline optimization: dropped latency from 24h to 5min with anomaly detection; 99.9% data quality SLAs via QA automation; data annotation lifted model precision 22%. • Production ML systems: real-time fraud model in Python and SQL reduced chargebacks 25%; • AWS data lake cut storage costs 30%; deep learning image recognition raised retail stock accuracy to 98%; predictive maintenance AI prevented $250K+ in annual equipment loss; supply chain forecasting cut inventory waste 15%; fintech data modeling streamlined compliance reporting 60%. Core Stack: • AI: OpenClaw, NemoClaw, OpenAI API, RAG, multi-agent orchestration, AI agent development, AI chatbot development, AI integration. • Code & Data: Python, SQL, JavaScript, REST, GraphQL, webhooks, OAuth, PostgreSQL, BigQuery, AWS, ETL pipelines, data mining, data annotation, data modeling. • ML / DL: TensorFlow, PyTorch, BERT, scikit-learn, computer vision, NLP, data science. • Analytics: Microsoft Power BI, Looker Studio, Google Analytics, Google Tag Manager, Excel, Google Sheets, data visualization. • Infrastructure & Security: Docker, VPS, Cloudflare Tunnel, mTLS, SSL, RBAC, audit logging, GDPR, SOC 2, HIPAA-aligned. Share your target metric and timeline, I'll map the fastest path to measurable impact with OpenClaw.
