I help mobile app teams trust their data and scale paid marketing spend. If your AppsFlyer dashboard says one thing, Meta Ads Manager says another, and nobody knows which one to believe — you don't have a tracking setup; you have a guessing game. I fix data discrepancies so you can scale campaigns with confidence. I will define exact conversion logic, event mapping, and tracking strategy your mobile campaigns need to optimize and scale. Leverage my 8+ years of performance marketing experience and 60+ completed AppsFlyer projects to handle the performance-side configuration of your attribution, ensuring ad networks get the clean signals they require. Here's what I help with in detail: 1. AppsFlyer & Mobile Attribution Setup • iOS SKAN 4.0 & SSOT Configuration: Designing conversion value schemas and configuring Single Source of Truth to deduplicate iOS data. • RevenueCat / Adapty + AppsFlyer: Advising on exactly which variables & arguments to pass in each postback for optimal attribution quality, along with subscription event mapping. • Attribution Audits & Investigations: Identifying data leaks and finding exactly why numbers don't match between paid channels and your MMP. • Knowledge-Sharing Sessions: Not only do I fix the misconfigurations, I also take you through a 1.5-2h deep-dive session. I'll walk you through the fixes, why I made them, and how to apply the captured data to inform your paid marketing decisions in this post-iOS14+ world. • Meta AEM Troubleshooting: I will tell you exactly why Meta's Aggregated Event Measurement doesn't work, how to fix it, and how to actually utilize it to your advantage. • On-Demand Training for Teams & Agencies: Learn what dashboards to use and when, how to customize them, and how to reduce the visual noise that MMPs push by default. We'll focus on metrics that actually matter for growth. • MMP Ecosystem: While AppsFlyer is my primary tool, I am also proficient with Singular and Tenjin. If you use another MMP, hit me up — I'll keep it straight whether I can help or not. 2. Multi-Channel Campaign Management & Strategy Once the tracking is sorted out, I manage and scale user acquisition across major networks, focusing on ROI/ROAS. I've handled monthly budgets up to $500K. • Apple Search Ads (ASA): Managing keyword bidding, custom product pages (CPP) utilization, discovery campaigns, and semantic structure optimization. • Google App Campaigns (UAC): Structuring campaigns for asset-group efficiency and setting up proper event-driven optimization. • Meta Ads (FB/IG): Optimizing account architecture for automated targeting, ensuring deep in-app event optimization (trials/purchases), and aligning ad manager data with actual MMP signals. • TikTok Ads: Implementing creative testing frameworks and scaling campaigns based on clean down-funnel data signals. • Twitter (X) Ads: I have a lot of experience here, though this is definitely not the channel to start with in mobile marketing. If you need it, we can discuss how to make it work. • On-Demand UA Consultations: Strategic advice for individuals and agencies on network selection (iOS vs. Android requires completely different strategies), tool stacks, campaign structuring, and scaling/killing triggers. Why Work With Me? Most technical MMP specialists don't know how to run ads, and most media buyers don't understand what happens under the hood of AppsFlyer. I do both. I sit at the intersection of data and performance, ensuring your ad networks receive the clean, rich signals they need to lower your CPA. Proven Track Record & Real Results: • 60+ AppsFlyer Projects Completed: I don't need an overly polished CV — my Upwork feedback from real clients is my resume, and I'm genuinely proud of it. I'm the guy people hire to fix, audit, and build tracking setups that work. • $500K+/Month Ad Spend Managed: I'm not afraid of scaling and managing heavy budgets across multiple platforms simultaneously. I know exactly how to push campaign delivery to its limits without burning cash. • From 50%+ to less than 10% Discrepancy: My setups typically bring data distortion between your ad networks and MMP down to a manageable, industry-standard margin. Real Growth Cases: • Scaled an app from $2K to $104K MRR in 12 months. • Co-managed a $1M/month app install campaign on Twitter (X) Ads. • Personally managed budgets up to $500K/month across Google Ads, Meta Ads & Apple Search Ads multiple times. Every project ends with total transparency. You leave with a setup your team actually understands & data you can trust. Looking forward to your message 👀

🏅 10 Years In Direct-Response Copywriting 🏅 VSL & Advertorial Mastery | Supplements | Health | Functional Nutrition 🏅 Static Ad Systems: TOF → MOF → BOF, Persona-Mapped 🏅 Market Sophistication & Awareness Mapping (Schwartz-Level Analysis) 🏅 Untapped Demand Zone Hypotheses Grounded In Deep Scientific Research 🏅 Proprietary AI Workflows Built In-House 🏅 60+ High-Value Contracts 🏅 100% Job Success Score, Top Rated Plus 🏅 On Upwork Since 2016 When did your market stop responding to the angles that used to work? With 10 years in the game, take my word on this for now: most brands, but especially those in health and wellness, aren't losing to better competition. They're losing to the same old repetitive yapping -- to sameness and laziness, and paying premium CPMs for the privilege. I'm a 10-year direct-response copywriter and creative strategist specializing in health and wellness: supplements, devices, functional nutrition, and the verticals adjacent to them. Now, as I'm sure you'll know if you've worked with them before, "hustle culture" copywriters start with the brief, the competitor swipe file, and the product benefits. Sometimes they get lucky and you see some results, but they mostly rely on luck. They juggle more clients than they can handle, they spin the same frameworks with subpar basic AI, and they take off with their paycheck. I start at zero. Before a single word gets written, I map the full demand landscape your buyer lives in. What else they're spending money on, what they've already tried and how it failed, what the news and their doctor are telling them daily, and where the emotional raw nerve is that your competitors haven't found yet. The research doesn't just inform the copy. It determines the mechanism, the angle, and the exact demand zone before a single headline gets written. That's where untapped demand zones live. And that merely hints at the depth I operate at. WHOAMI? A one-man direct-response operation that thinks like an agency. I build VSLs, advertorials, sales pages, and full static creative systems for brands that are scaling, or were scaling until the obvious angles stopped working. You know the wall. Spend goes up. ROAS drops. Every new creative looks like a variation of the last one. The market has gone deaf to your category's standard claims. To that wall, I am the wrecking ball. I use proprietary research and creative systems to identify the demand zones your competitors haven't touched, then build the positioning, copy, and creative strategy to own them. And I work alongside your media buyer. Data in, strategy out, iterate fast. Any market is a blue ocean if you know what you're doing. This level of strategic depth usually takes a team, but I outperform teams for a living. Plus, I bring the speed and accountability of one person who owns the whole thing. TO SCALING BRAND OWNERS & SERIOUS AGENCIES, I SAY: I know what it feels like to watch a funnel bleed out while your team recycles the same five angles with slightly different hooks and calls it "split testing." And I know what it's like to pay an agency to swipe competitor ads and dress them up in a new font. That ends here. Let's talk. MAIN DELIVERABLES ➡️Advertorials ➡️VSL & UGC Scripts ➡️Sales Pages ➡️Statics WHY I CHARGE TOP DOLLAR Because you hire me to get top dollar. There’s this quote below by my favorite copywriter: “Pay peanuts, says Jimmy Goldsmith, and you get monkeys.” ― David Ogilvy, Ogilvy on Advertising WHAT MY CLIENTS SAY Adam Ross [D2C Ecommerce | $14,106.66 Contract] "Excellent, professional copywriter. Worked with Kosta for over a year and he provided an amazing service, his copywriting was extremely creative and he crushed it every time. Eventually we finished the project, but would hire again in a heartbeat." Anita Elisha [D2C Ecommerce | $600.00 One-Off] "We were looking to have an existing, well-performing longform salespage rewritten to beat control. Kosta took the time out to meet with us and fully understand our objectives. He communicated really well and asked specific, targeted questions required to come up with a stellar direct response marketing piece. Overall a great experience!" EXTRA: THE TLDR CLIENT REVIEW I LOVE THE MOST [Confidential | $5,450.00 Contract] "Kosta’s incredible ability to sell to core emotions of entire markets helped us scale our offers to hundreds of thousands in revenue in just over 5 months. It was a pleasant surprise to come across the real deal on Upwork! Every funnel he made for us enabled us to leverage UDZs & mechanisms rather than big ideas, which was game-changing, because as he put it: “Offers that are based on the big idea tend to die out pretty fast; The big idea is a big idea, then it becomes a medium idea, then it becomes a small idea, then it becomes whatever. Because the big idea gets copied and copied… While the ‘core emotions’ and UDZ approaches can’t be copied, because practically no one knows about it!”"

⭐️ 8+ Years of Experience | 🔥 $250M+ Managed in Facebook Ads | 🏅 Top 1% Upwork Expert | 🚀 For Brands Ready To Scale ❌ I don’t do trials. ❌ I don’t work with “make me rich overnight” projects. ❌ I don’t work with dropshippers chasing quick wins. ❌ I don’t work with people looking for the cheap option.

If you need someone to “test a few ads and see what happens,” I’m not the right fit. If you want someone who has managed serious budgets, understands creative strategy, knows how to read data, and has helped brands scale through Facebook and Instagram ads, we should talk.
