I help growing teams replace manual reporting, scattered spreadsheets, and unreliable dashboards with automated data workflows they can trust. Most clients come to me when: • reports are still updated manually every week • data lives across spreadsheets, PDFs, APIs, and dashboards • leadership does not fully trust the numbers • one person on the team is holding the reporting process together manually • the dashboard exists, but the workflow behind it is fragile I’m a Data Automation & BI Consultant with 4+ years of experience building practical reporting systems, analytics workflows, dashboards, and data automation tools for business teams. I’ve worked with global clients across fitness, insurance, media, entertainment, and B2B data. My projects have included ETL pipelines, reporting automation, dashboard systems, Excel/PDF processing, analytics layers, and large-scale data infrastructure. Recent outcomes: • Reduced manual reporting time by 80% for a multi-location fitness business using BigQuery, Apps Script, and Looker Studio • Automated PDF data extraction and Excel/VBA reporting workflows for a U.S. insurance project • Completed a complex multi-department data migration project in 5 months against a 2-year estimate • Built large-scale workforce/lead data infrastructure using Python, DuckDB, Parquet, Metabase, and automated export views What I can help with: • Manual reporting automation • KPI dashboards in Looker Studio, Metabase, or Power BI • Python / SQL data pipelines • Data cleaning, transformation, and validation • BigQuery / database reporting layers • Excel and Google Sheets automation • PDF and document data extraction • GA4/GTM tracking QA and conversion reporting • Workflow documentation and handoff How I work: • I diagnose the workflow before building • I design the data structure before the dashboard • I validate the numbers before handoff • I build in clear phases or milestones • I document the setup so your team can maintain it For messy reporting or automation projects, I usually recommend starting with a paid Data Workflow Blueprint: source review, metric logic, data model, automation priorities, and a phased build plan before implementation. Tools & skills: Python, SQL, BigQuery, DuckDB, Metabase, Looker Studio, Google Apps Script, Excel VBA, Power BI, Snowflake, R If your team is spending too much time copying, cleaning, checking, or rebuilding reports manually, feel free to message me with what is broken, what you have tried, and what needs to work first.

4+ years building BI end-to-end Infrastructure. I sit with the ambiguity, ask what your team hasn't, and translate fuzzy business goals into a clear data model and KPI framework that holds up under scrutiny. 🧠 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐫𝐢𝐧𝐠 𝐭𝐨 𝐲𝐨𝐮𝐫 𝐭𝐞𝐚𝐦 🔹 Ambiguity → Clarity: I define the right questions and metrics before building anything, so you measure what matters, not what's easy. 🔹 Semantic & Data Modeling: Star schemas, slowly-changing dimensions, reconciled grain, single source of truth 🔹 Scalable Architecture: Pipelines and models designed for "Day 2", maintainable, cost-aware, documented, built to grow instead of breaking at scale. 🔹 Context Integration: I unify Stripe, Shopify, Zoho, GA4, Ads platforms, etc. and CRMs into one coherent ecosystem that mirrors how your business actually operates. 🔹 Narrative & Decision Design: Every visual answers a business question and points to an action, analysis a CEO can act on in seconds. ⚙️ 𝗧𝗲𝗰𝗵𝗻𝗶𝗰𝗮𝗹 𝗧𝗼𝗼𝗹𝗯𝗼𝘅 🔹 BI & Viz: Power BI, Looker Studio, Zoho Analytics, Metabase, Apache Superset, Domo, Databox 🔹 Modeling & Query: SQL, DAX, Power Query (M), Python, dbt, Excel 🔹 Warehousing: BigQuery, Cloud SQL, Snowflake, SQL Server, MySQL, Firebase 🔹 Pipelines & ETL: Make, n8n, Fivetran, Apps Script, Cloud Run, Windsor AI, Coupler IO, Supermetrics 🔹 Sources: Stripe, Shopify, Zoho CRM, GA4, Google/Meta/TikTok Ads, Search Console, etc. 🔹 AI layer (the plus): OpenAI & Claude APIs, Claude Code, Codex, conversational analytics, anomaly detection, predictive models, and agent workflows for automated briefings & alerts 🚀 𝗪𝗵𝗮𝘁 𝗦𝗲𝘁𝘀 𝗠𝗲 𝗔𝗽𝗮𝗿𝘁 🔹 Business-first, not tool-first: I start with your objectives and constraints, not your dataset. 🔹 End-to-end ownership: From auditing sources and defining KPIs to modeling, building, and publishing, I run the full lifecycle. 🔹 Transparency: You own your data and infrastructure. I document every step, so nothing is a black box. 🔹 AI as leverage, not a gimmick: I automate the repetitive parts so the strategic parts get more of my attention. ⭐ 𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗦𝘁𝗮𝘆 🔹 Reliable communication and clear expectations , no micromanagement needed. 🔹 Insights in plain language, for technical and non-technical stakeholders alike. 🔹 Proactive: I diagnose and recommend, not just deliver charts. 🔹 Consistent delivery, on time, with care. 💡 𝗟𝗲𝘁'𝘀 𝗕𝘂𝗶𝗹𝗱 𝗬𝗼𝘂𝗿 𝗗𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝗦𝘆𝘀𝘁𝗲𝗺 If your business generates data but not clarity, let's fix that. I'll design the model, architecture, and dissemination layer that turn your numbers into a durable competitive advantage, clear, scalable, and genuinely yours.

I build data pipelines, attribution systems, and reporting layers for adtech, marketing, and analytics teams. My strongest work is in cleaning up fragmented source data and turning it into reporting that teams can actually trust, especially when data is spread across ad platforms, analytics tools, spreadsheets, internal databases, and custom APIs. I typically work across the full stack of analytics delivery: data ingestion, transformation, warehouse design, business logic, automation, and reporting. What I help with: 1. Ad platform and marketing API integrations 2. BigQuery-based ETL / ELT pipelines 3. Attribution and performance reporting systems 4. Warehouse modeling and reporting layers 5. Data validation, reconciliation, and automation 6. Custom dashboards and internal tools in React / Next.js 7. Backend workflows using Python, Node.js, and serverless infrastructure Platforms and sources I’ve worked with: Meta Ads, Google Ads, GA4, DV360, TikTok, LinkedIn Ads, Reddit Ads, Shopify, Salesforce, Jira, Google Sheets, Google Forms, Firebase / Firestore, SQL databases, and custom internal data sources. Examples of the work I do: 1. Build ingest-to-insight pipelines for marketing and ad platform data 2. Design reporting layers that make KPIs usable across campaigns, clients, and channels 3. Implement attribution and event tracking logic for cleaner performance analysis 4. Restructure analytics stacks into more maintainable warehouse models 5. Automate repetitive reporting and operational workflows across cloud tools and APIs 6. Build custom dashboards and internal data products when off-the-shelf reporting is too limiting Tech I use regularly: Python, SQL, Node.js, TypeScript, BigQuery, GCP, AWS, Airflow, Cloud Run, Cloud Functions, Lambda, SQS, Firestore, DynamoDB, GitHub Actions, React, and Next.js. I’m a strong fit for teams that need more than a one-off script or dashboard. If you need someone who can take raw source data and turn it into reliable reporting and usable internal systems, message me.

I help businesses connect their scattered tools and data sources into unified, automated systems that actually work. If you're dealing with data trapped in silos, manual reporting processes, or platforms that don't talk to each other, I build the pipelines and integrations that fix that permanently. My core work involves connecting systems end-to-end: stitching together payment platforms, ad networks, CRMs, and analytics tools into clean, automated data flows using BigQuery, Fivetran, REST APIs, and Cloud Run. I specialise in server-side GTM and GA4 implementations that feed reliable, first-party data into warehouses where it can actually be used ,not just collected. I've built integrations across Stripe, Meta Ads, HubSpot, Shopify, Klaviyo, Recharge, CareStack, DICE, and more, typically landing data in BigQuery or Snowflake and surfacing it through Looker Studio dashboards that update themselves. The goal is always the same: remove the manual work, make the data trustworthy, and give teams a single source of truth they can act on. With 4+ years across eCommerce, publishing, B2B SaaS, hospitality, and healthcare, I've seen most of the messy integration problems that come with fast-growing tech stacks. I bring both the technical depth to wire things together properly and the business context to make sure what I build is actually useful. If you need someone who can map out your data architecture, connect your systems, and automate the reporting layer on top, let's talk. Skills Overview: Systems integration & data pipeline architecture BigQuery & Snowflake SQL pipelines and data modelling Server-side GTM, GA4, and first-party data collection API integrations (Stripe, HubSpot, Shopify, Klaviyo, Meta CAPI, etc.) ETL/ELT orchestration with Fivetran and Cloud Run Automated reporting in Looker Studio Data quality assurance and event tracking audits Stakeholder communication and technical documentation
