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
