Are you looking to get more from your ad spend and scale your business with hands-on PPC management? Then stay a while and listen. 13+ years in PPC (since 2013). 5,800+ hours on Upwork. 100% Job Success and a long list of 5-star reviews from vetted clients. For 7+ of those years, I ran paid media at a Top-Rated Google Premier Partner agency, scaling accounts to over $200,000/month without sacrificing ROAS. Here's what that means for you. Your ads, handled. Search, Shopping, Performance Max, Display, plus Microsoft/Bing and Meta. I build clean account structures, fix what's bleeding budget, and scale what's working. I write custom Google Ads scripts that tag products by performance and split them into tiered campaigns, so every dollar goes where it converts. Your tracking, trustworthy. GA4, GTM, server-side tracking, and ecommerce purchase tracking. I don't optimize on broken data. I verify the setup first, then make decisions you can actually rely on. Your systems, connected. This is where most specialists stop, and I keep going. I integrate HubSpot and GoHighLevel (GHL) for offline conversion tracking, so your campaigns optimize toward real revenue, not just leads. And I build n8n automations that sync conversions, route leads, automate reporting, and add AI where it saves you time. Analytical, technical, and fluent in English. If you want a paid-media expert who also speaks fluent automation, let's talk. Best, Ciprian Nedelcu

🔋 Google Looker Studio & Analytics Certified Expert, specialized in building Business Intelligence dashboards that turn raw data into decisions. I also manage Google Ads campaigns, which means I build dashboards around the metrics that actually drive performance. I've been obsessing over Looker Studio for the past 6+ years. I have worked on both marketing and data with high-profile companies: 📈 Marketing agencies (e.g. GAIN, TRGT Digital, SearchScientists) 📈 Telecom brands (e.g. Tello, KeepCalling) 📈 SaaS companies (e.g. AdBadger) 📈 eCommerce shops (e.g. Charles Tyrwhitt, Loop, Nastimed) I also run KPIs.Studio, a Looker Studio dashboard service for businesses that want ongoing BI without a full-time analyst. 🪆 Why work with me over other freelancers? • My professional background is marketing: this means I understand the value of data-driven decisions and how to look for that data. • I've built hundreds of dashboards since 2018. I know what a head of growth actually needs to see on a Monday morning. • I've published on this topic via the “Eyes on the KPIs” interview series and collaborations with MeasureSchool. • I have a strong eye for design: Your dashboard will be polished, on-brand, and built for the people actually looking at it. • I work with what you have. I'll give you practical, cost-conscious recommendations. Almost every client I've worked with has Google Sheets somewhere in the mix. If your current reporting makes you work for answers, let's fix that!

Most paid media reports celebrate ROAS, while the P&L tells a different story. I build and operate the AI-powered revenue engine underneath the ads — the system that turns spend into pipeline, CAC payback, and net profit for B2B SaaS teams (and DTC brands scaling against real margins). Expert-Vetted on Upwork (top 1% of talent). $8M+ in ad spend managed across my career, documented ROAS of 5–18 across SaaS, eCommerce, and travel, and a 24% CPL cut for a B2B SaaS client—largest single account: $100k+/month. I'm not an ad manager who bills by the hour — I'm an AI Growth Systems Operator. I own the paid engine end-to-end (Google Ads, LinkedIn Ads, Meta) and orchestrate the surrounding channels — analytics, lifecycle, GTM tracking — so the whole funnel pulls in one direction: pipeline and profit, not vanity dashboards. Where I help: - Revenue Engine Audit: I map your entire acquisition funnel and show exactly where budget and pipeline leak — broken attribution, wasted spend, funnel gaps — with a clear path to profit. - Revenue Engine Build: I set up the system end-to-end — paid channels, GA4/GTM tracking, reporting, and the automation that runs it. - Fractional Growth Operator: I own strategy, budgets, and reporting as your outsourced Head of Performance — the ongoing engine, not a one-off project. Whom I work with: - B2B SaaS (seed–Series B) that needs a qualified pipeline, not just leads or clicks. - Professional & business services (legal, finance, accounting, advisory) where a single new client is worth thousands — so lead quality beats lead volume. - AI & tech companies with a strong product but no repeatable demand engine. - DTC / eCommerce brands scaling paid acquisition against real margin targets. How the AI layer works: custom n8n + Claude/Gemini and Make workflows plan campaigns, pull and read reports straight from the ad accounts, and surface optimization moves as they happen. This isn't about doing the work faster — it's about doing more of the work that matters: underperformers get caught the day they slip, more tests run per cycle, and judgment stays hands-on. The automation absorbs the busywork; the strategy stays with me. Primary platforms: - Google Ads (Search, PMax, Demand Gen), - LinkedIn Ads, - Meta Ads, - Microsoft Ads, - TikTok Ads, - GA4 / GTM / Looker Studio for tracking and attribution. Start with a Revenue Engine Audit: I'll show you exactly where spend is leaking and what the profitable path looks like — then we decide if a longer engagement makes sense.
