    Hi! I'm James, a Harvard Computer Science graduate, an ex-Googler, and CTO-level fullstack software engineer. I have 21 years of work experience, and can meet in-person if you’re in or near silicon valley. I believe that brilliance is good; reliability is better; and most important are integrity and compassion.. I help awesome people doing amazing things in the world; and I will deliver you delightful tech and tech leadership, on time, on budget, with full transparency and candor. I provide the following services: - Fractional CTO: I will work with you to clarify your visionary goals into an actionable technical roadmap; help you secure funding if necessary; and then run the technical operation start to finish. - Web and native app development: From napkin-sketch ideation to 7+ figure production, I will deliver intuitive, elegant digital experiences to your customers, from top-rated games and 3D virtual worlds to FDA compliant medical software, on the web and on devices. - Solving “unsolvable” tech problems. Examples of real projects I was engaged for: building a low power “hurricane proof” weather camera (Weather Channel); assisting with the development of the Semantic Reactor (a Google/Alphabet internal project); building a physical neural network entirely out of glass. - Technical project management: I will ensure your project runs on time and on budget, with incremental milestones and mitigated risks, using the best of Agile and PM tooling. I can manage teams large and small. - Productionalizing Research. Give me the research paper or the patent, I’ll make it real and scalable. - Consulting, with lawyers and attorneys, as a software engineering resource, for instance with respect to contracts and other legal matters (like Privacy Policies or GDPR/CCPA concerns). - Modernization of old technology: I will migrate and modernize your legacy application using the industry’s latest best practices. I have experience with performance tuning, scalability, devops, security hardening, penetration testing, and much more. - Teaching and coaching: I teach middle and high schoolers competitive coding. I enjoy tapping into every student’s life story and motivations. I also advise entrepreneurs and can act as a sounding board for personal and professional goals. - Solutions Architect: I provide comparative analysis of modern cloud technologies and explanations of how to use them for different scenarios.

    I am the founder 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 almost a decade of 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

    I develop high quality iOS and Android mobile apps using Swift, Kotlin, Java, SwiftUI, Jetpack Compose, Firebase, and APIs as needed depending on project. Through my hard work and dedication to meet all project requirements, I've earned Upwork's Top Rated Plus rating! I am self-motivated, self-directed, dependable, reliable, and trustworthy. I've been an independent consultant for most of my career. I know how to conceive a project, get the work done independently, and successfully deliver the project. I excel at testing so when the project is done, it is done! No one likes to put together a large programming team where there are tons of duplicated effort and miscommunication. I can be your single-source developer for both Android and iOS phones and tablets! Most apps also need a back-end. No need for a separate web app programmer that can cause timeline problems and miscommunication! I can write the back-end utilizing Firebase then integrate it into all versions of your mobile app. Using a single source, you control the timeline, you avoid integration issues, and everything flows smoothly. You probably cut your delivery time in half! Every week, I develop mobile apps, cloud functions, and cloud tasks, mainly for Internet of Things using Bluetooth and Firebase. Every week, I am using: Kotlin Java Javascript, typescript, node.js (back-end) Swift Jetpack Compose SwiftUI Bluetooth (Android) Core Bluetooth (iOS) Firebase Auth (user authentication, login) Firebase Firestore (database) Google Cloud Functions Google Cloud Tasks (scheduled based on a trigger) Firebase Crashlytics Firebase and Apple push notifications Google sign-in Apple sign-in As an expert Mobile App Developer, other skills I can deliver: Flows, co-routines, async tasks, flow state. WiFi configuration: static IP, dns, enterprise, add and update. JSON serialization/parcelization. NFC tag reading. Develop Maven library. Network Service Discovery (NSD). Direct ipp open protocol for printers. REST - okhttp and retrofit expert for network calls, including calls to Amazon AWS. User accounts with encryption tokens. Encrypted keystore. Push notifications (Firebase, Apple, in-app). Silent package Installer and updater. Kiosks management. Google maps with location updates, custom map markers, annotated map markers. Custom User Interface features with custom graphics, backgrounds, themes, and styling. User authentication. Credit card validation. Stripe credit and debit card processing. Google Pay processing. Glide or Picasso image handling/transformation. Image upload as file or bitmap. Dark mode activation. Launch and welcome screens with terms of service. Multi-threaded environment solutions and multi-tasking co-routines. Dynamic updates of screens from incoming push notifications. Phone dial, messaging, camera photo-taking, gallery browsing. Backwards compatibility to older versions of Android. Forwards compatibility to latest versions of Android. Room database. App publishing on Google Play Store and Apple App Store. App testing on Firebase. Firebase/Maps API keys. Troubleshooting and expert debugging of crashes/bugs/memory leaks in legacy apps. Development environment: Gradle multi-flavor (multi-version) builds Github and bitbucket version control Slack or Jira team communication Figma wireframes Swagger REST API calls Github or Jira project management and collaboration Roll-outs to 50 million user install base A recent review on Upwork: "Stephanie did a superb job to make our Bluetooth hardware on-boarding via Android very reliable. She was able to find the corner cases and then find solutions for those corner cases! This was a difficult challenge as Bluetooth permissions, capabilities, and processes vary greatly between Android OS versions and devices. The on-boarding process is simple, elegant, and extremely user friendly. It has been an honor and pleasure working along side Stephanie." Other: Protocol Stacks, embedded systems, multi-tier networking systems Fortune 500 Java and C/C++ Trainer, Expert Witness Computer Science degree, Certified Project Management Professional Native English Speaker Available to work any timezone Background: I've used many protocol stacks: Point-to-point, TCP/IP, sockets, WiFi CDMA network, Bluetooth, other wireless networks. I've developed application systems with 4 tiers of communication layers: Device to Handheld, Handheld to PC, PC to mini-computer, mini-computer to mainframe. Embedded Systems: Transponder readings sent to handheld which then transferred data to desktop computer which interfaced to IBM mainframe. Cable system "set-top" box. Assembly code for micro-chips.

    ➡️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. As you can see from my outstanding Upwork reviews, I have provided App Store Optimization (ASO) and certified Apple Search Ads (ASA) management to 100+ App Store / Google Play apps, including 10+, top 100 apps in their categories (BetMGM, 21Moves, Novel Effect, DAFUQ, Qmee, Oceanic+, Hushed, Weather Fit, Stronger, Daze Cam, Inshallah, etc.). Get your mobile app discovered and downloaded by the right App Store & Google Play users. My proven App Store Optimization (ASO) and certified Apple Search Ads (ASA) expertise maximize the impact of your app store and Google Play listing to outrank your competitors and lead your niche. 📈 Hire me to increase your app's visibility 📈 Expert End-to-End App Store Optimization Services: ✓ Assess current search rankings & performance ✓ Target keywords with high search volume & relevance ✓ Revise App Store title, description page, promo text, & metadata ✓ Manage localization of listing for relevant countries ✓ Create App Screenshots, logo, & app preview video ✓ Build & manage Apple Search Ads campaigns, which directly impact organic search algorithms ✓ Audit listing in App Store Connect for compliance with best practices ✓ Propose features missing from your app that affects ASO ✓ Obtain accurate data to optimize the app using premium ASO tools ✓ Update you with insightful reporting about your app's visibility ✓ Adjust the ASO based on which downloads turn into active users 👇What you should know about me:👇 🚫 No Predatory Tactics 🚫 I'm the only ASO specialist who shares the keyword rankings I have achieved for my clients. Take a look below at my Upwork portfolio. I hate seeing agencies that do not intend to fulfill the initial offer's goal. Market conditions, competitor influence, and the app's niche are never assessed – and client needs never enter the equation with too many marketers. I am not focused solely on extracting the most money from you before you realize the futility of the exercise. Preying on uninformed clients is not my strategy. 🚫 No Low-Quality App Store Optimization 🚫 Writing your app description and "researching" keywords may seem like a task for your virtual assistant or intern. It's not. I won't waste your time "blindly" trying to increase your app's ranking or stuffing it with irrelevant keywords and saying my work is done. My deep understanding of how ASO ties into mobile app growth allows me to consider variables most don't. I'll drive long-term results because I get how the mechanics of the App store influence search. Or how the dynamics of Apple Search Ads and organic search work together, unlike a standard SEO consultant. 🟢 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. Which mobile app analytics tools do I use ❓ I use premium Apptweak ASO software. 👔 Experience 🖥️ I provide mobile app marketing full-time for 100+ App Store & Google Play mobile app clients and growing. This includes ASO, Apple Search Ads UA, localization, conversion rate optimization, and growth marketing. Beyond this role, I have founded successful online companies, three of which I sold each for six-figure amounts. This entrepreneurial background spanning 15 years forms the basis of my self-taught digital marketing expertise. See my work history listed in the section below for more details. 💡Do you have questions? Send me a message, and I'll provide answers clarifying and explaining what I can do in more detail. Until then, consider that over 80% of mobile app downloads start inside the App Store via search. App Store Optimization (ASO) is crucial for your marketing efforts. But most digital marketers who know Search Engine Optimization (SEO) cannot help. App Store & Google Play algorithms aren't just like Google web search algorithms. I will help you grow your organic downloads, increase conversions, and acquire more users.
