Your GA4 numbers don't match your ad platforms. Conversion events fire twice, or not at all. And every month someone rebuilds the same dashboard by hand because last month's stopped being believable. The tracking underneath is broken, so nothing built on top of it can be trusted, and you're left guessing which number to spend against. I fix the whole chain, end to end: from the tag firing on your site, to the BigQuery pipeline that cleans and unifies the data, to the dashboard your team makes decisions on. I'm an Analytics Engineer who builds the data engineering layer (automated pipelines, BigQuery modeling, BI) on top of deep, hands-on tracking implementation roots. That combination is the point. Because I own both the server-side tracking and the pipelines it feeds, the data stays coherent the whole way down, with no hand-offs between three specialists who each blame the other when the numbers don't add up. I work almost exclusively with e-commerce brands and marketing, growth, and advertising agencies (white-label welcome). I speak ROAS, MER, CAC, and LTV, so you tell me the business goal, not the technical spec. --- What I build Marketing & e-commerce data pipelines (GCP / BigQuery), the core of what I do: - Automated ETL/ELT from GA4, Shopify, ad platforms (Meta, Google, TikTok), and CRM into BigQuery - Ingestion via Python, dbt, Fivetran, Stitch, or the GA4 native BigQuery export - BigQuery data modeling: staging, intermediate, and mart layers, partitioning, clustering, incremental models - Data cleaning, normalization, deduplication, and identity stitching across sources - Orchestration and scheduling on GCP: Cloud Run, Cloud Functions, Pub/Sub, Cloud Scheduler - Cost optimization, query tuning and table design so the warehouse scales without surprising your bill - Deliverables: automated pipeline, single source of truth in BigQuery, attribution-ready datasets, documented and modeled tables refreshed on schedule, a warehouse your next analyst can actually read Tracking & analytics implementation, the foundation the data depends on: - GA4: advanced e-commerce, custom events, funnels, attribution-ready data layer - Google Tag Manager, client-side and server-side (Stape or GCP) - Conversion APIs: Meta CAPI, TikTok Events API, Google Ads enhanced conversions, Snapchat, LinkedIn - Client-to-server migration to recover conversions lost to iOS, ITP, and ad blockers - Consent Mode v2 and CMP setup (OneTrust, Usercentrics), first-party capture, hashing, deduplication - dataLayer, JavaScript, and DOM work for custom event tracking - Deliverables: documented tracking plan, validated event and conversion setup, tag and trigger audit, numbers that reconcile across platforms BI & reporting, the part your team actually looks at: - Looker Studio dashboards powered by BigQuery (Power BI / Tableau / Metabase on request) - Revenue analytics, channel performance, funnels, ROAS/CAC/LTV scorecards - Automated SQL transformations and scheduled workflows, no manual monthly rebuilds - Deliverables: CEO-ready dashboard, automated refresh, documentation your team can follow --- Why clients hire me: I combine data engineering, analytics implementation, and BI automation into one workflow. Instead of isolated dashboards or pipelines built on shaky tracking, you get a full-stack, maintainable, accurate data system, with one person accountable from the tag on your site to the number on the dashboard. Agencies can put me behind their own client work: on calls if you want me there, invisible if you don't. Certifications: - Google Cloud Professional Data Engineer (2025) - Google Analytics Individual Qualification (verified by Upwork) - Meta Certified Marketing Developer (Credly) Whether you need a GA4-to-BigQuery pipeline, broken tracking fixed, Shopify analytics modeling, or a complete analytics foundation, tell me what you're trying to decide with the data, and I'll build the system that gets you there.

I help SaaS companies, and enterprises identify critical security vulnerabilities before they become costly breaches, compliance issues, or business disruptions. As an Application Security Consultant and Penetration Tester, I specialize in uncovering real-world security weaknesses across web applications, APIs, network infrastructure, cloud environments, and modern technology platforms. My goal is not only to identify vulnerabilities but also to help organizations understand their security risks, prioritize remediation efforts, and strengthen their overall security posture. I have worked on security assessments involving enterprise applications, banking platforms, healthcare systems, cloud infrastructures, and business-critical applications. My experience includes identifying authentication flaws, access control weaknesses, business logic vulnerabilities, network misconfigurations, cloud security gaps, API security issues, and attack paths that automated scanners frequently miss.

If a website fights back - enterprise anti-bot, hidden APIs, protected platforms - that's exactly what I've specialized in for 9+ years. Data extraction at scale from sources that don't want to give it up: real estate portals, marketplaces, retail, court and government platforms. When standard scraping tools and AI scrapers hit a wall, that's where my work starts. Real estate and property data, marketplace and price monitoring, court and public records, B2B lead generation - different sources, same problem: getting clean data out reliably, and keeping the pipeline alive long after the demo. Whatever the source, you get working infrastructure that runs daily - not a zip file with a script in it. 20+ years in technology, with a network security background. I turn extraction into systems clients run their businesses on: deal sourcing, lead generation, price monitoring, market intelligence. Clients usually come to me when: - An existing extraction process keeps breaking and the data it feeds can't be trusted anymore - The data lives behind protected sites, anti-bot, or a hidden API no off-the-shelf tool reaches - Prices, catalogs or listings need tracking across marketplaces and competitors at a cadence no manual process can hold - The work spans many sites, counties or platforms and needs one system, not one-offs per source - Public records need turning into lead generation and skip-tracing workflows - The data has to stay current - ongoing monitoring, not a one-time export Where I'm genuinely hard to replace: Protected sites and hidden APIs. Akamai, Cloudflare, DataDome, PerimeterX, reCaptcha, device fingerprinting. Mobile and web reverse engineering to reach hidden APIs when the protocol allows it - direct platform connections over headless browsers. And if a target is technically or legally not viable, I'll tell you that too, before you spend money. Court and government platforms. Tyler Odyssey, Socrata, Granicus, Laserfiche, CivicPlus, ArcGIS and a few dozen more I've already mapped. Here's the thing most people miss: what looks like hundreds of different government websites is usually a handful of underlying platforms. On a recent project, 250+ government sites came down to 10 integrations. Build the adapter once and the same system covers an entire state. Your project starts further ahead because of every project before it. Pipelines that stay alive. Monitoring, alerting, retries, data quality checks, AI-assisted classification where it makes sense. I've taken over plenty of projects where the previous solution worked great in the demo and died three weeks later. Getting the data out is half the job. I also wire it into the systems your team already runs - CRM, database, sheets, scheduled reports (HubSpot, Postgres and the like) - so the pipeline ends where you actually work, not in a raw file. Selected work: - 150,000+ grocery products monitored every 2-5 hours across major UK retailers - 125,000+ automotive parts synchronized daily from marketplaces behind enterprise anti-bot - Court records pipeline detecting ownership distress signals across 225+ counties, feeding real estate acquisition workflows - 100,000+ real estate listings deduplicated and merged with ownership, tax and valuation data for AVM workflows - 96,000+ business entities extracted from government registries, classified by industry with LLMs, enriched with contact data - 5,000+ municipal meetings scraped and analyzed with AI keyword intelligence across five government platforms; adding a new jurisdiction requires zero code changes Not sure if your target is even extractable? Every project starts with a short feasibility check: I map the source, the protection layer and the realistic effort, so you know what is viable before committing to a build. If it cannot be done reliably (or legally), I tell you upfront and you spend nothing chasing it. --- web scraping, data extraction, price monitoring, product data, catalog data, marketplace data, ecommerce data, competitor intelligence, real estate data, property data, real estate leads, mls data, foreclosure data, court records monitoring, government data, municipal data, foia, lead generation, b2b data, skip tracing, anti-bot bypass, bot detection, cloudflare, akamai, datadome, perimeterx, captcha solving, device fingerprinting, reverse engineering, hidden api, headless browser, proxy rotation, browser automation, data pipeline, scheduled extraction, data orchestration, etl pipeline, python, scrapy, playwright, postgresql, supabase, api integration, data normalization, data enrichment, data validation, document extraction, llm integration, demandstar, tyler odyssey, tyler energov, granicus, primegov, legistar, civicplus, laserfiche, accela, socrata, arcgis hub, ckan, opengov, clerk of courts, property appraisers.
