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. Veriphone credit card readers with communication to mainframes/cloud. Java Trainer for Sun Microsystems (before they were bought out by Oracle) for 2 years. C/C++ Trainer for Intel University (part of Intel) for 2 years. Expert Witness in trial against a top insurance provider regarding their Java based application.

𝒀𝒐𝒖 𝒉𝒂𝒗𝒆 𝒂 𝒃𝒓𝒊𝒍𝒍𝒊𝒂𝒏𝒕 𝒊𝒅𝒆𝒂. 🚀 Maybe it's an innovative app, a sleek website, or a cutting-edge digital product. But finding the right person to bring it to life? That’s the real challenge. You need a designer who understands user behavior and a developer who can turn that vision into a seamless experience. 𝐖𝐡𝐚𝐭 𝐢𝐟 𝐈 𝐭𝐨𝐥𝐝 𝐲𝐨𝐮, 𝐲𝐨𝐮’𝐯𝐞 𝐟𝐨𝐮𝐧𝐝 𝐛𝐨𝐭𝐡?🔥 I started my journey in UX/UI design, 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐛𝐫𝐚𝐧𝐝𝐬 𝐥𝐢𝐤𝐞 𝐀𝐝𝐢𝐝𝐚𝐬, 𝐀𝐢𝐫𝐛𝐧𝐛, 𝐓𝐨𝐰𝐠𝐢𝐠, 𝐏𝐨𝐥𝐚𝐫 𝐃𝐞𝐬𝐢𝐠𝐧, 𝐀𝐥𝐟𝐫𝐞𝐝 𝐈𝐧𝐜. 𝐔𝐒𝐀, 𝐅𝐨𝐧𝐞 𝐌𝐞, 𝐚𝐧𝐝 𝐦𝐨𝐫𝐞. Over the years, I’ve successfully delivered 230+ UX/UI projects that don’t just look great, but drive real impact. 👥 My designs have helped businesses boost user retention, increase revenue, and enhance product adoption. 📈 But as I worked with startups and businesses, I saw a gap, clients would come to me for designs, then struggle to find a developer who truly understood their vision. 𝐖𝐡𝐲 𝐬𝐡𝐨𝐮𝐥𝐝 𝐦𝐲 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐠𝐨 𝐞𝐥𝐬𝐞𝐰𝐡𝐞𝐫𝐞 𝐭𝐨 𝐛𝐮𝐢𝐥𝐝 𝐭𝐡𝐞 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐬 𝐈 𝐝𝐞𝐬𝐢𝐠𝐧? That didn’t sit right with me. That realization led me to master mobile app development, ensuring that the same care and precision that goes into the design is reflected in the development process. That’s when I dove into mobile app development. 𝐎𝐧𝐞 𝐄𝐱𝐩𝐞𝐫𝐭, 𝐓𝐰𝐨 𝐖𝐨𝐫𝐥𝐝𝐬 Now, I bring both UX/UI and mobile development under one roof. Whether it's a pixel-perfect design or a full-fledged app, I create digital products that are intuitive, scalable, and high-performing. From e-commerce platforms to AI-driven solutions, I turn ideas into market-ready products. 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐇𝐢𝐫𝐞 𝐌𝐞 I offer a streamlined, end-to-end approach. You’re not juggling multiple freelancers, you’re working with someone who understands the full lifecycle of digital products. ✅ UX/UI Design – Figma, Adobe XD, Sketch ✅ Frontend – React.js, React Native, Swift, Kotlin, Flutter ✅ Backend – Node.js, Django, Python, Flask ✅ Databases – PostgreSQL, MySQL, MongoDB, Firebase 📢 𝑪𝒐𝒍𝒍𝒂𝒃𝒐𝒓𝒂𝒕𝒊𝒐𝒏 𝒊𝒔 𝑲𝒆𝒚 (𝑹𝒆𝒂𝒅 𝑻𝒉𝒊𝒔 𝑩𝒆𝒇𝒐𝒓𝒆 𝑯𝒊𝒓𝒊𝒏𝒈 𝑴𝒆!) If you want a person who just nods and follows orders, I’m not your person. I believe great things happen when both sides communicate, challenge ideas, and push for the best. I expect clear communication, commitment, and involvement. If you’re ready to invest in your project, I’m ready to make sure that investment pays off. It's rare to find a designer who develops or a developer who designs. But when the same person who designs your app also builds it, the results are seamless.

Hey Guys, Thanks for stepping in, Let's talk business straight away. I work on $35/hr with no turn arounds So, you're looking at someone who eats, sleeps, and breathes mobile apps. For over eight years now, I've been diving deep into what makes a great app tick, whether it's crafting slick cross-platform experiences with React Native and Flutter, or going native with the nitty-gritty of iOS (Swift, Objective-C) and Android (Kotlin, Java). I've even got my hands in the world of IoT mobile apps, making sure everything looks and feels just right with solid mobile app design skills. I've had the chance to build all sorts of cool stuff, from fitness and health apps that actually get used, to e-commerce platforms that make shopping a breeze, and even some serious fintech and delivery solutions. Think payment apps, grocery delivery, even booking a table or snagging event tickets – I've been in that mix. Plus, I've tackled the social scene with networking and dating apps, and gotten into the logistics of transportation, manufacturing, and the fascinating world of IoT and even blockchain. Oh, and if you've got a pesky bug in your iOS, Android, Flutterflow, or React Native app, chances are I've squashed a few of those in my time too, not to mention working on everything from cleaning apps to live shopping and media sharing platforms. When it comes to the tech stuff, I'm comfortable across the board. On the backend, I'm fluent with AWS, Firebase, and building robust REST APIs and GraphQL solutions. For mobile, React Native and Flutter are my go-to for cross-platform, and I've got over a decade of experience under my belt with Kotlin and Swift for native development. I've also spent a good chunk of time with Javascript, ReactJs, NodeJs, ExpressJs, Typescript, Laravel, and PHP, especially when it comes to building the dashboards that power these apps. I really get the difference between native and hybrid approaches and I'm all about smooth third-party API integrations. Microservices on AWS? Yep, familiar with that too. And when it comes to databases, I've worked with everything from MySQL and MongoDB to Redis, SQLite, Elasticsearch, and PostgreSQL. Basically, I'm all about building solid, user-friendly apps from the ground up, whether it's designing the UI/UX in Figma or Adobe XD, coding in Kotlin, Swift, Flutter, or React Native, or setting up the backend with the MERN stack or PHP. I even keep an eye on the latest trends like AI, AR, and IoT to see how they can enhance mobile experiences. So, if you're looking for someone to build a custom mobile app for iOS or Android using React Native or Flutter (maybe with Supabase or Firebase?), need a Web API built or a backend developed with MERN or Laravel, want to make sure your app is top-notch with quality assurance, or just need a hand with UI/UX design or ongoing maintenance, I'm your guy.
