I’m an AI Systems & Data Engineer with an M.S. in Data Science from Johns Hopkins. I build production AI and data infrastructure: RAG pipelines, agent workflows, ETL systems, vector databases, analytics dashboards, and cloud data platforms that turn messy operational data into reliable software.
My work sits at the intersection of AI, data engineering, data analytics, and applied data science. I can help design the pipeline, clean and model the data, build the dashboard, explain the business story, and connect the system to AI tools like RAG, semantic search, LLM workflows, Pinecone, OpenAI, Claude, Postgres, Snowflake, AWS, or Azure. In practice, that means I work across the full path from raw data to insight to production application.
Recent work:
• Architected a Postgres ↔ Pinecone sync layer for a 3.6M-document legal research corpus, keeping vector metadata coherent with the transactional store through a revertible, checkpoint-resumable migration protocol.
• Canonicalized ~4,000 messy document-type strings into 47 UI-facing categories against a live 57K-docket production database with zero downtime.
• Built a custom NLP summarization model for 10-Q filings at the Federal Reserve Bank, extracting quantitative insights for analyst review.
Stack: Python, SQL, PostgreSQL, Snowflake, Azure SQL, AWS, Azure Data Factory, Microsoft Fabric, Power BI, dbt, Airflow, Docker, Git, LangChain, OpenAI API, Anthropic API, Pinecone, pgvector, VoyageAI, RAG pipelines, ETL/ELT pipelines.
Background: MS Data Science (Johns Hopkins, 3.8 GPA), formerly Hedge Fund Credit Analyst at JPMorgan Chase.

I help businesses replace manual, repetitive work with reliable AI automation one system I built resolves 2,000+ support tickets per day at 94% auto-resolution, and another eliminated 6+ hours of manual work daily by connecting AI directly to a client's real tools.
I don't build fragile AI demos. I started in data engineering and Power BI, so I build AI agents and automation on top of clean data, real integrations, error handling, and reporting your team can actually trust and monitor in production.

✓ AI automation workflows in n8n, Make, and Zapier connecting CRMs, email, documents, SaaS tools, and databases
✓ AI agents for support, operations, research, and internal workflows with memory, approval gates, and human-in-the-loop control
✓ RAG chatbots and document intelligence using OpenAI, Claude, LangChain, and vector search

𝐖𝐡𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐡𝐢𝐫𝐞 𝐦𝐞:
Most AI automation fails because it isn't connected to clean data, real permissions, audit trails, or proper error handling. I focus on production systems your team can use, monitor, and improve not one-off scripts that break in a week.
If you're trying to automate a manual process, connect AI to your existing tools, or turn messy data into reliable decisions, send me a short description of your workflow. I'll map the safest architecture with you before we build anything

I’m an ex-Shopify data scientist and analytics engineer with 6+ years of experience, currently working at CoinBase. At Shopify I worked on production-scale analytics systems across the data warehouse ecosystem; ingestion, storage, data modelling, and analytics.
I now help businesses design and build data warehouses. I fix storage and ingestion issues, implement data governance, design and orchestrate data modeling, and build analytics workloads for your team.
I mostly work in the Google ecosystem (GCS, BigQuery, Looker), but can use whatever platform your business needs (e.g., Databricks, Snowflake, Microsoft Azure, etc.) I have a Databricks certification, as well as have developed hundreds of dashboards across all the different platforms.
Why clients hire me:
✅ Deep data platform knowledge (3 years at Shopify)
✅ Clear communication + Loom walkthroughs

I architect, build, and implement AI systems that turn business data into decisions - conversational analytics, predictive ML models, and autonomous AI agents that automate real workflows. Backed by 16+ years and 400+ delivered projects, I bridge the gap most AI freelancers can't: I don't just prototype models, I design the end-to-end solution and engineer the data foundation, pipelines, and cloud architecture that make AI production-ready, secure, and scalable.
I work as a true solution partner - architecting, executing, and implementing around each client's custom business use case, timeline, and budget. From a single AI agent to a full data-and-AI platform, I right-size the solution so you get maximum value without overspending.
WHAT I DELIVER

Analytics Engineer | BigQuery, dbt, Looker Studio — from ad platforms to CRM to internal tools
With 3 years of experience as a Business Analyst and Tool Enablement Specialist — including work at TELUS International — I sit at the intersection of two things most freelancers only do one of: building internal tools that teams actually use, and modelling data that leadership can actually trust.
Clients come to me when they have one of these problems:
— Their team is running on disconnected spreadsheets and manual handoffs
— Their ads and CRM data exists but no one can read it clearly
— They need a real internal system, not another workaround
🔹 What I build:
1. AppSheet Applications (my core specialty)
Task management and operations tools
Inventory and IT request tracking systems
CRM and workflow apps for non-technical teams
Data ingestion pipelines from Google Drive into BigQuery
Result: your team works in one structured system they actually adopt
2. Data & Reporting (BigQuery · dbt · Looker Studio)
Connect Meta Ads, Google Ads, and CRM data into one place
Clean and model your data using dbt and BigQuery
Build Looker Studio dashboards with correct metrics — ROAS, CTR, CPC at every level
Result: numbers you can act on, not just look at
🔹 Real examples of what I've delivered:
✔️ Built an IT inventory and request tracking app used across departments
✔️ Modelled Pipedrive CRM + Meta Ads data into a unified performance dashboard
✔️ Created a task management system replacing a tangle of spreadsheets
✔️ Built calendar and operations tools connected to BigQuery as the backend
🔹 Tools I work with:
AppSheet · BigQuery · dbt · SQL · Looker Studio · Pipedrive · Meta Ads · Google Ads · Google Sheets · Google Drive
I combine a deep understanding of how teams actually work with the technical skills to build systems around that. Every solution I deliver is something your team can run independently — not something that breaks the moment I leave.
If you want cleaner operations, clearer data, or both — let's talk.
