 As a 👍TOP RATED PLUS👍 freelancer with an official Upwork certificate, I guarantee top-tier results. 🌟 Highlights
 • Ranked in the 🥇”Top 10”🥇 best designers in the "vk com" redesign contest (50,000+ participants❗) • 10+ years of experience in high-quality design and marketing solutions
 • I have an elite team of professionals for most complex projects Senior Product Designer & AI Expert – I don’t just design, I ship. From idea to production using Figma, Shopify, Wordpress and AI (Cursor, Codex, Antigravity, Claude). Conversion-focused. Built to scale. I love what I do and put my soul into my work.

Twelve years writing code, two of them running product at MotionArray, where I led the team through its acquisition by Artlist in 2020. I build the thing, I know why the business wants it built, and when the work outgrows one person I have 30 engineers behind me. Most profiles here offer one of those three. What I do hands-on Frontend and full-stack in Angular, Vue, React, Next, Nuxt and Capacitor, with Node, Laravel, PHP and C# behind it. Shipped and maintained bikeflights, skilltrakker and myhrconfidant . Comfortable in codebases somebody else wrote and abandoned, which is most of what I get asked for. AI, specifically I'm a founding engineer at BuildBetter.ai, an AI product platform used by B2B teams that turns call recordings, tickets and support conversations into structured, cited deliverables. The work is the unglamorous part of shipping AI: retrieval over a company's own documents so answers are grounded instead of plausible, structured extraction from messy input, and the evaluation and cost work that decides whether a feature survives real usage. Most products don't need a model, they need the right context reaching one. I'll tell you which you're dealing with before you spend money finding out. The team behind me I founded and run Roraima Devs, a U.S. LLC with 30+ engineers across the U.S., Colombia, Argentina, Venezuela and the Dominican Republic. 15+ clients, many with us 3+ years, 9 years on Upwork, 6 years as a U.S. company. Reviews under Roraima Devs on Trustpilot. What that means for you: I take the work I can do well myself, and when a project needs frontend, backend, mobile and DevOps moving at once, I can staff it in parallel instead of stretching one timeline into six months. You decide which shape you want, and you always know exactly who is touching your code before it happens. Larger scopes can run through the agency contract if that suits you better. How I work I ask questions before estimating. If your idea has a cheaper path than the one you arrived with, I'll say so on the first call. If I'm not the right fit, I'll say that too. Start with a 30-minute call and we'll look at what you have.

➡️My App Store Optimization earned the #1 ranking on the App Store Games - Trivia category in under 1 month for DAFUQ, a previously unranked app. I’ve worked with 150+ apps of all sizes, from startups to global brands like Hard Rock and MGM, achieving impressive results. My experience includes working on more than 15 top-100 apps, with notable examples like BetMGM Sportsbook (#4), Stadium Live (#9), Hard Rock Neverland Casino (#43), Timeleft (#55), Vivino (#38), Qmee (#20), Stronger (#37), DMV Genie (#88) Novel Effect (#47), Minutes (#57), Sole Supplier (#88), DMV Genie (#88), Sole Supplier (#90), and more. [ DATA-DRIVEN APPROACH ] These results come from a transparent, data-driven approach that focuses on improving keyword rankings on both Google Play and the App Store, improving organic downloads, conversion rates, retention rates, app ratings, and ultimately work to grow in-app purchase and subscription revenue. [ INDEPENDENT FREELANCER – I DO ALL THE WORK MYSELF ] Let's set up a free, 30‑minute video screenshare call 📞 to discuss how I can help your app achieve long‑term organic growth. Just send me a message, and I’ll share my calendar 📅 via Upwork. [ QUANTIFIABLE SUCCESS STORIES ] • Increased 21Moves’ monthly subscription revenue from $500 to $10,000 in just 3 months. • Boosted Qmee’s organic downloads from 13,000 to over 70,000 per month in 2 years. • Launched an ASO strategy that generated over $100,000 in monthly revenue. • Scaled apps to earn more than $300,000 per month. [ MOBILE APP MARKETING SPECIALITIES ] • ASO Metadata Optimization • Keyword Research • Cross-Localization (Japanese, Korean, French, etc.) • 7-Figure Apple Search Ads (ASA) Ad Campaigns • App Store Screenshots • App Preview Videos • Custom Product Pages (CPP) • Product Page Optimization A/B Testing • Conversion Rate Optimization (CRO) • App Ratings & Reviews Growth • In-App Events • Push Notifications & In-App Messaging Drip Campaigns • App Onboarding User Flow • User Retention Strategies • In-App Purchases & Subscriptions • App Development Feature Roadmaps [ NO PREDATORY TACTICS ] I can't stand agencies that fail to deliver on their promises. Too many make excuses like shifting market conditions, algorithm updates, low budgets, or increased competitor spending, rather than taking responsibility and adapting their strategy. Their focus is often on extracting as much money as possible before clients realize the strategy isn’t working. I don’t operate that way. My approach is transparent, data-driven, and built around real results, not empty promises. [ YES TO DATA ] I don't pretend to have superhuman intuition. I know how to find, understand, and apply ASO data to create and improve your app store product page. How to measure the impact of the ASO efforts is just as significant, so we're confident in the effects of the ASO efforts. No, "it sounded good" is not a sufficient explanation. Whether you’re an indie developer or a large studio, my ASO strategies can help you reach more users, improve conversion rates, and build long-term organic growth. Let’s talk about how I can help your app achieve its full potential.

Right now, someone is asking ChatGPT to recommend a business like yours. It is naming one. The question is whether that business is you. I do what most SEO specialists can't: rank you on Google AND get you recommended by AI. Traditional SEO gets you found when someone searches. AI search visibility gets you named when someone asks ChatGPT, Perplexity, or Siri for a recommendation. You need both now, and I build both into every page. I optimize across all 10 platforms where buying decisions now start: Google · ChatGPT · Perplexity · Gemini · Google AI Overviews · Meta AI · Grok · Siri · Alexa · Google Assistant WHAT MAKES MY WORK DIFFERENT Standalone blog posts stopped building authority in 2024, and most existing pages were never built for AI in the first place. Content without schema, entity signals, and speakable structure is invisible to AI, no matter how well it is written. Whether I am writing new pages, rewriting your service pages, or optimizing what you already have, I engineer every page at the section level across all six ranking signals: → SEO · Google organic ranking → AEO · featured snippets & People Also Ask → AIO · Google's AI Overviews → GEO · ChatGPT, Perplexity, Gemini citations → VEO · Siri, Alexa, Google Assistant → E-E-A-T · the trust signals AI weighs most, and the YMYL compliance that medical, legal, and financial content lives or dies on Most freelancers optimize for one signal. A few do two. I build all six into every page, because leaving one out means you are invisible somewhere your customers are looking. And I do not write one-off pages. I build content clusters: interconnected pillar pages and supporting content that establish deep topical authority, the structure Google and AI reward most. Each page strengthens the ones around it, so your rankings and authority compound instead of starting from zero every time. WHAT THIS MEANS FOR YOU → Your pages become the source AI quotes when customers ask questions → Your business gets named in ChatGPT and Perplexity where competitors used to win → Siri and Alexa read your name when someone asks for a recommendation → Every page compounds, an asset that keeps working long after it is published INDUSTRIES From medical aesthetics and legal to home services and beyond, I have built AI-visible content across high-stakes verticals, including YMYL industries where trust signals are non-negotiable. The method works anywhere your customers are searching. Let's turn your content into the answer AI recommends. Message me and let's make it happen! - Joy Herro
