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 👀

They have been curious about my business my vision, our company goals and related development needs. The team has helped me to imagine and express the user journey in actionable ways. They have given me the tools and feedback to prioritize features and provided streamlined, clear and consistent communication at every step. In many instances I found the inertia of the project came from them which is unusual and exceptional. The quality of the work they did in helping me and my company build a beta iOS app is high quality. While we have completed the first stage of development I intend to work with the Goldfish team to further develop my application. They are flat out good people and a pleasure to work with. I highly recommend them from end to end: project planning, project management and timely output. ❞ 🗣 Review From Check!st - An IOS Airlines Industry App 🗣 𝗪𝗲 𝗼𝗳𝗳𝗲𝗿 “𝗳𝘂𝗹𝗹-𝘀𝗲𝗿𝘃𝗶𝗰𝗲” 𝘀𝘂𝗽𝗽𝗼𝗿𝘁 𝘁𝗼 𝗼𝘂𝗿 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘄𝗶𝘁𝗵𝗶𝗻 𝘁𝗵𝗲 𝗳𝘂𝗹𝗹 𝗮𝗽𝗽 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 𝗰𝘆𝗰𝗹𝗲.

Hello! I'm Lucas. I am a highly experienced software developer who specializes in app and mobile game development, and I have been building apps, games, websites, and other software for over 15 years. I graduated with honors from the University of California: Santa Cruz with a degree in Computer Science (with a focus in game design). Upon graduating, I worked as an engineer for Intel for several years. After that, I decided to become an independent developer and have managed my own app development company for the past 9 years. I have developed and released several popular apps and games of my own design for Android and iOS, and have worked on countless projects on a freelance basis. These projects have ranged from small bug fixes/optimizations, to prototype designs of new games, apps and utilities, to fully functional apps for small studios and large corporations alike. Though I have focused expertise in mobile app and game developments, I am also quite skilled in related fields such as UI/UX design, web development, backend programming, and technical art creation (Adobe Photoshop/Illustrator/etc.). I am constantly learning new skills and work hard to keep my knowledge up to date with new frameworks, platforms, tools, and best practices. I have recently embraced agentic AI code development to speed up production time, but I never "vibe-code" or accept code changes without reviewing and understanding what has changed. AI is a valuable tool, but not a replacement for a professional developer. Don't waste your money on a bloated production team, and don't risk your dream project with an inexperienced or inattentive freelancer. Regardless of the needs of your project, big or small- prototype or production-ready, I'm your dev. Let's build it!
