    Seasoned Silicon Valley engineer with 10+ years of experience expert in iOS dev. I have worked on a number of successful iPhone apps published in the App Store including one Webby award nominee in 2015 on which I was technical lead. I know XCode, Swift, Objective-C, storyboard dev, image processing, graphics and video. I have worked at successful startups and know client/server technology. I also have experience with different audio and video codecs, image formats, converting and streaming video. I have experience working on a commercial desktop application for the Red One video camera. And putting together back-end websites that integrate with UX designs using Ruby on Rails and deploying website solutions to both heroku and Amazon AWS. I am able to architect higher-level solutions for a web-based API in REST communicating with thin iPhone and Android clients via JSON. I have done video and other research for Walt Disney Imagineering R+D. I also worked together with Motorola and Sprint on the first camera cell phones and video phones. I also put together an MVP (minimum viable product) for a financial sector startup company from the ground up that secured first round financing and a deal with Homeland Grocery Stores. As to "bugs," I have used a number of different bug tracking tools including the latest Atlassian JIRA solutions. I have used subversion, github and bitbucket for both public and private repos. I have worked extensively with QA departments and managers for product releases and bug tracking. I have also worked with international teams delegating tasks and on localization. I have used basecamp for project management. I have also developed my own iPhone applications and have a couple of apps that do reasonably well in the App Store. Most of my experience has been in industry working in Silicon Valley and parts of Los Angeles and Santa Barbara. I am now at the point where I would like to move on to freelancing, consulting and contracting. I am a very effective engineer and I learn quickly. I am good at delivering release software on time using an Agile methodology working together with designers, other engineers, project managers, international teams and QA departments. If you want quality work at a reasonable price I do charge a decent rate because I am worth it.

A little more about me, I’ve launched several dozen complex iOS apps. Collectively, they have grown to many millions of active users. Check below for just a few of the apps I have worked on!

    Self motivated mobile app developer that has built multiple mobile apps from the ground up. I learned what users care the most is how the mobile app looks and feels (UI/UX). Through my experience of over 6 years building out my own mobile app ideas below and building my clients apps, I've gained massive amounts of knowledge on how to create beautiful looking mobile apps that look and run great. I was able to get my personal app project SongMakr to over 200 downloads a day through ASO (App Store Optimization) in the app store with users creating songs everyday. SaveMe Receipt App - iOS - This app allows users to store their receipts and get notifications when their receipt expires. - Used Firebase for authentication, database, and file storage. RentRoom iOS App - This app allows tenants the ability to pay their rent and contact their landlord regarding any maintenance issues. - Used Firebase for authentication, database, and file storage. Meip Music iOS App and Android App - This mobile app allows the user to record their voice over music and the app mixes it to create a song. The user can post the song to their profile or share it over Facebook, twitter, etc. You also could like other people’s songs and follow and message them a song. - The app used Parse for the backend to save user accounts and their songs. I used Swift programming language for the iOS version and Java for the Android version. SongMakr iOS App - With the shut down of parse i decided to remove my Meip app and build SongMakr. - The app uses Google Firebase. MapChat iOS App - This mobile app allows you to post anonymously at your location on a map. Other users can look at posts in their area. - Also used Google Firebase InstaPics iOS App - To get more practice with Firebase i built an instagram clone called InstaPics. - You can create an account and post pictures with filters and also you post to the feed. - Open sourced it on Github so other people can use it. Skills: - Mobile App Development - iOS App Development (Swift, SwiftUI, Objective C, Xcode) - Android App Development (Java, Android Studio) - Firebase - Realm - Core Data - MapKit - Google Maps Here are some reviews from previous clients: "Solomon Woldegebriel is a top notch mobile app developer. When starting a new technology- focused business, some of the things you need most from your mobile app developer are timely communication, sufficient skills, and the ability to interpret non-developer language. Solomon excels in all three areas. He made me comfortable along the development process of my app by staying in constant communication with me and replying in a timely manner. Solomon let me know of any issues as they came up, which allowed me to stay on top of my business planning. I would not have been able to successfully launch my company without Solomon's abilities. I highly recommend him to work in any capacity!" - Upwork Client "Solomon is a great guy to work with. Goes above and beyond and even out of his own way to find better solutions and implements it. It is a pleasure to work with him again and going forward he will be our go to person for all iOS projects." - Upwork Client Message me now if your looking for an expert mobile app developer to get started on your project!

    Hey I'm Eric! I'm a highly skilled iOS developer that's ready to build your iOS app from the ground up. A Little About My Background ------------------------------------ I've built over 20 iOS apps from scratch, launched 9 on the App Store, and sold two of them! The most recent app I built for a client was called Kwiks – a TikTok-styled social media app. I came on board after the app was already in development, and improved video feed performance so dramatically that they offered me a full-time position. I also have a collection of personal apps which you can view by searching "Eric Solberg" on the App Store. The one I'm most proud of is a social networking app called "#Social - Meet people like you". It incorporates a fully fledged in-app messaging feature and implements complex database queries (using Firebase). My most popular app so far ranked in the top 100 "Entertainment - Top Paid" category on the App Store – with over 100,000 organic downloads in less than a year – before it was acquired. What I Offer --------------- - Extensive experience in the iOS app space, including feature ideation, software development, app launch and marketing knowledge, and everything in between. - Perfectionist mindset – I pride myself in exceeding expectations and delivering an excellent product. That means delivering on time, on budget, and with code quality at the forefront. - Fast development – I obsess over your project from start to finish, and can deliver your app in weeks, not months. - Communicative availability – I almost always have my phone on me, so message me anytime! Technical Skills ------------------- • Swift • Xcode • Storyboard and/or UIKit (No SwiftUI) • All Apple Frameworks • Any 3rd-party framework • Firebase Master • UI/UX Design w/ Figma (if needed) Conclusion -------------- Thanks for considering me for your project. If you think we could be a good fit, or even if you just have a couple questions, feel free to reach out. At the very least, I can give you some answers and point you in the right direction. I look forward to speaking with you, - Eric

    I have designed and completed many iOS/Swift, Unity/C#, React Native/Javascript, and Flutter/Dart-based apps as a sole, lead, or co-developer and published them on the Apple App Store and Google Play Stores. As a contractor for NASA, I published a Unity/C# iOS/Android augmented reality app for their Visitor Center in Goddard, Maryland, called "WeatherSats AR." I am currently working on multiple contracts in Native iOS, Android, and Unity. On the backend, my expertise is in Firebase, Firebase Functions, and now Microsoft Azure. I co-founded two iOS startup companies with other developers. One is a social media app for craft beer, and the other is a SwiftUI animation-based app where you can draw a multiple-choice question animation and share it with and challenge other users. I have a B.S. in computer science from Rutgers University in 2004, graduating with a 4.0 GPA.

    I build web apps on React as well as iOS apps with Swift. Need a website (or web app) and a native iOS app? No problem! I have 8+ years of experience writing efficient web apps in React, as well as complex websites on Next.js. I have a sense of good UX and UI, so I approach every mock-up very thoroughly. I've also led a team of frontend engineers, mentored junior devs and acted as a Scrum Master to the team. I love Swift and SwiftUI! Started my professional path as an iOS Dev and still making progress in this area by bringing more great ideas to life. My app Timerange currently has more than 40 000 users around the globe. I’m currently doubling down on SwiftUI, writing all my latest apps using this framework, and I also inject SwiftUI into my older UIKit based projects.
