Most mobile apps fail because nobody thinks about what happens after launch. I've built apps that broke into the App Store Top 50, generated real revenue for clients, and I run my own subscription apps with 10K+ active users. I know what moves MRR and what doesn't. When you work with me, you're not just getting a mobile developer. You're getting someone who has personally: - Designed paywalls and onboarding flows that convert (not just "look nice") - Run paid acquisition (Meta, TikTok, Apple Search Ads) for subscription apps - Optimized for retention, churn, and LTV - the metrics that actually decide if your app survives - Built the ASO and organic growth side (keywords, screenshots, A/B tests) - Provided ongoing technical support so the product keeps improving post-launch If you're building a subscription app and want it to sell itself not just ship and pray - let's talk. I take on a small number of clients where I can be involved beyond the build: helping with monetization strategy, growth, and long-term technical health. Some of what I bring: - 10+ years building iOS and Android apps (10M+ combined downloads) - 200K+ MRR generated to clients - My own subscription apps with 10K+ users - Apple Pay / Google Pay / RevenueCat / subscription infrastructure - CI/CD, white-labeling, and the boring-but-critical engineering work - AI integrations (LLMs, on-device ML) where they actually improve the product Looking to launch, grow, or rescue a subscription app? Send me a message - happy to give you honest thoughts even if we don't end up working together.

Expert-Vetted (Top 1%) full-stack developer — $1M+ earned across 177 projects. WordPress, WooCommerce, Shopify, and eCommerce are my bread and butter: theme builds, plugin customization, migrations (Webflow-to-WordPress, platform swaps), shipping/payment integrations, and ongoing maintenance. I also build AI agents, RAG systems, and automations (Claude, OpenAI, n8n, Make) when the project calls for it — intake flows, lead triage, support bots, and workflow automation. Recent wins: - Head eCommerce developer for a growing DTC brand - SEO migration from Webflow to WordPress - Recovered 33% of lost Meta conversions for a DTC brand - AI intake flow + EHR integration for a healthcare company - React Native + Node.js full-stack app I work in plain language, move fast, and ship things that actually run in production. Replies within hours.

Game and application veteran team well-versed in cross-platform SDKs and native application development for iOS and Android. Also have tons of relevant experience working with Sony, Microsoft and Nintendo platforms. Deep development experience with Unity, Unreal, React Native, Corona/Solar2D, SwfitUI and Java.

112 projects, 100% success rate. I don't take on work I'm not confident I can deliver. I help founders and teams turn an idea (or a half-working prototype) into a production SaaS or EdTech platform that actually ships and gets used — not just demoed. Most of what I build sits at the intersection of full-stack web development and AI: RAG systems, AI agents, chatbots, voice apps. But the AI is only there when it earns its place — if a plain database query is the right answer, that's what you get. Projects I'm proud of: 💡 An adaptive SAT/ACT preparationplatform built with React, Node.js, and Python, powered by the OpenAI API and developed with input from Stanford PhDs — it turns raw practice scores into a learning path that adjusts after every session. 💡A RAG-powered document search tool, built with Python and LangChain and connected straight into SharePoint and Dynamics 365, that indexed 300,000+ internal files and cut research time by 75%. 💡A HIPAA-compliant AI note-taking tool, built with Node.js and Whisper on a secure cloud backend, that turns a psychiatrist's spoken session straight into a structured clinical note — saving hours of their paperwork time daily. 💡A voice-controlled drive-thru ordering system, built with React Native and Node.js, now running in real locations and cutting order processing time by 30%. 💡A GDPR-first Zendesk AI copilot, built with Node.js and the OpenAI API with a custom data-scrubbing pipeline, that drafts agent replies from ticket history while stripping sensitive customer data before it ever touches the AI model. How I work with clients I'm direct and to the point — you'll get plain answers on scope, cost, and timeline, and if something in your plan won't work, I'll say so early, not after the invoice. I think about your project with a business mindset first: what needs to ship, what it needs to earn or save you, and what can wait — not just what's technically fun to build. No jargon dumps, no vague "it's in progress" updates. Full Stack Development Across Every Stack As a Full Stack Developer Python and Python Full Stack Developer, I build AI backends with Django, FastAPI, and Flask alongside React frontends. As a Full Stack Developer React and Full Stack Developer React Node, my default stack for new SaaS builds is React/Next.js + Node.js and TypeScript. As a Full Stack Developer AI, I fold LLM and RAG features directly into that same codebase instead of bolting them on as a separate service — working with OpenAI, Anthropic Claude, Gemini, Mistral, and Llama models, orchestrated through LangChain, with vector databases like Pinecone and Elastic Search grounding responses in real data instead of guesses. Where a project needs voice, I bring in Whisper, ElevenLabs, and VAPI for speech-to-text and real-time voice AI, and I build autonomous AI agents and multi-step workflows using tools like Hugging Face and PyTorch when custom model work is called for. For projects on a different foundation, I work as a Full Stack developer PHP and Full Stack Developer Laravel on legacy systems or client-mandated stacks, and as a WordPress Full Stack developer when a CMS site needs custom functionality beyond themes and plugins. I've also worked as a Webflow developer for fast, no-CMS-overhead marketing sites and landing pages. Whether you need a Full Stack Web Developer for a browser-first product or a Full Stack app developer for something React Native-based on mobile (with Swift and Kotlin where a fully native module is needed), I own the project front-to-back — design, build, ship, and support. On the data and infrastructure side, I work with PostgreSQL, MongoDB, MySQL, and Supabase, deploy on AWS, Microsoft Azure, and Google Cloud Platform, and build with compliance in mind from day one — HIPAA, GDPR, SOC 2, and PCI-DSS — for HealthTech, EdTech, and enterprise SaaS clients who can't afford to get that part wrong. If your project needs someone who'll own it end to end, send over what you've got — idea, spec, or prototype — and let's see if we're a fit.

I am a cofounder of Create Neptune, a software and game development studio focusing on creating fun, user-focused, and beautiful apps and games for mobile (iOS / Android), web, PC, and consoles. Our developers and designers have worked on franchises like Scrabble and The Sims, and with companies like Mattel, EA, 2K Games, Estée Lauder, The New York Times, AppLovin (Lion Studios), and Boombit. I have led app development projects from the concept phase to post-launch marketing, and I am an expert in all stages of the application and game development life cycle. I am particularly attuned to the commercial side of application and game development: I was previously a hedge fund analyst focusing on the energy and power sector, and a mathematics, economics, and finance instructor. At Create Neptune I have published dozens of mobile games, with our most successful app Paddle Clash reaching millions of users worldwide since publication in mid-2020 and maintaining a 4.9 / 5.0 globally and 4.7 / 5.0 in the US on the App Store. Aside from our published portfolio, I have concepted, prototyped, and built dozens of other 2D and 3D games for a variety of clients, from Fortune 500 mega-caps to bootstrapped startups. I have over a decade of experience in game and app development. I typically work in Unity (C#), but I have also worked on successful native apps for iOS (Xcode, Swift) as well (Pandamonium, iOS, 4.7 / 5.0 on App Store). I have worked on numerous apps from the concept and prototype phases to post-launch marketing, so I can be with you every step of the way in the creative process. Specifically, in addition to coding, I can provide concept and prototype work, professional-quality UI and UX, 2D and 3D artwork, and marketing services. Lastly, I am very familiar with the post-launch app marketing process and publishing process on both the App Store and Google Play, and I would be happy to help you and your team with my experience. I began my career in finance as a mergers and acquisitions investment banker and an energy and power analyst at a distressed debt fund, completing the largest leveraged buyout in fund history and managing a book of $1.3 bn of energy and power assets. I have also worked as a mathematics and economics instructor, designing several advanced mathematics and financial analysis courses. My studio regularly works on cutting edge applications in Unity. Just a few examples: • We developed Scrabble Vision (Mattel), an AR companion application for the physical Scrabble board game, in Unity • We developed and helped design RYZ Home (IKIN), a holographic AR application, in Unity • We developed and designed software for a private research study (Estée Lauder), using OpenCV and AR, in Unity • We developed and designed StarStarter (Arcade Therapeutics), a digital anxiety treatment game, in Unity • We developed and helped design Skylar's Run (Thynk), a digital ADHD treatment game, in Unity • We developed and designed Highlandia (Highlands Community Charter), an English language learning game featuring 10 different mini-games, in Unity
