Request your free fixed rate price quote from a professional on this job today! I founded CTLR PLUS SOLUTIONS, a Tennessee-based marketing analytics, business intelligence, AI workflow, and MVP development lab. I am 40, first-generation poor, and the father of five kids. I built this business to provide intelligent service, create opportunity, and solve problems that cost clients money, time, confidence, and momentum. We fix broken tracking, messy dashboards, disconnected tools, unclear revenue data, and custom technology problems. 𝐒𝐞𝐫𝐯𝐢𝐜𝐞. 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞. 𝐑𝐞𝐥𝐚𝐭𝐢𝐨𝐧𝐬𝐡𝐢𝐩𝐬. 𝐘𝐞𝐬, 𝐒.𝐈.𝐑.! Service means clear communication. Intelligence means we diagnose, build, test, and improve. Relationships means we do not win one contract and disappear. Proof I maintain a 100% Job Success Score (This is totally not easy!), Top Rated Plus status, and 120+ client engagements. Review my Upwork feedback. plussolutions.ai. drgreencoconuttree on YouTube to see how I think, explain, and solve. I am not an outsourcing agency hiding behind a generic logo. The work carries my name. 💠 What do we fix? Most organizations are not short on tools. They are short on clarity. You may already have GA4, GTM, Google Ads, Meta, Shopify, HubSpot, Salesforce, Looker Studio, Power BI, Airtable, Zapier, Make, BigQuery, Snowflake, or a CRM. The problem is simple: the tools do not agree. The website says one thing. GA4 says another. The CRM says something different. The ad platform takes credit for everything. The dashboard looks nice but does not answer the real business question. 🔹 We fix tracking, connect data, build dashboards in Looker Studio and Power BI, support BigQuery, Snowflake, and SQL workflows, and build custom AI/MVP tools. The goal: See what drives revenue, what wastes money, and what must happen next. How your money works 🌐 Step 1: Audit Most engagements start with a $99 Audit. We review GA4, GTM, Google Ads, Meta, events, website tracking, attribution, reporting gaps, dashboards, and next steps. The audit answers: What is broken, missing, confusing, or underbuilt? Step 2: Fix We fix GA4 events, GTM setup, Google Ads conversions, Meta Pixel/CAPI, form tracking, click tracking, checkout tracking, CRM mapping, UTMs, attribution, and reporting mismatches. If tracking is wrong, the dashboard is decoration. We help you stop guessing. 🔷 Step 3: Build Some clients need a $2,500 dashboard sprint. Others need executive reporting, Power BI, Looker Studio, BigQuery/Snowflake architecture, AI workflows, MVPs, scrapers, Chrome extensions, internal tools, automations, or private business systems. Larger AI and MVP builds can range from $15k to $30k+, depending on complexity. The point is to build the right thing. Step 4: Consult Building the thing is not enough. We help clients interpret results, explain performance, train teams, review funnels, analyze campaigns, understand attribution, improve dashboards, and make better decisions. A dashboard without interpretation is just a pretty screen. Step 5: Retain 🌀 Markets change. Platforms change. Tracking breaks. Campaigns launch. Teams ask new questions. Many clients continue through advisory retainers, analytics support, development retainers, or ongoing business intelligence relationships. Typical retainers range from $1,800 to $6,800+/month, depending on scope. We are always in the solution business. Are we alone? No. I lead strategy, diagnosis, business logic, client communication, and solution direction. CTLR PLUS SOLUTIONS also uses trusted developers, data engineers, and automation specialists when needed. You get senior strategy plus build support. How do we interview? Message me on Upwork and ask for a free thought-partnering session or $99 audit of your stack. We clarify the problem, review the tools, identify the fastest path, and decide if we are the right fit. Next steps 🔵 Hire or Invite. Fund the $99 Audit. Send access to GA4, GTM, Google Ads, Meta, website, CRM, or dashboard tools. 𝙔𝙤𝙪𝙧 𝙛𝙧𝙞𝙚𝙣𝙙 𝙖𝙣𝙙 𝙖𝙣𝙖𝙡𝙮𝙨𝙩, -𝙈𝙖𝙧𝙘𝙪𝙨 If your business is tired of unclear tracking, disconnected tools, confusing dashboards, expensive guesswork, or half-built systems, you are in the right place. Tell your friends we do: GA4 upgrade and event tracking completed successfully. Power BI labor productivity and budget dashboard delivered. Data Studio dashboards created with excellent communication. Strategic consulting helped clients clarify testing, user experience, and performance. MVP and Chrome extension projects moved clients in the right direction.
