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 possess extensive expertise as a seasoned full stack developer with over 9 years of experience. I have built and published numerous projects, including websites and mobile applications, across various domains such as entertainment, social media, finance, e-commerce, real estate, healthcare, and more. I have successfully completed 17 projects, both large and small in scale. I have a deep understanding of fundamental skills such as JavaScript and TypeScript, and I am highly proficient in recently popular modern libraries and frameworks such as React, Vue.JS, and Angular. Additionally, I possess strong expertise in back-end development using Node.js with frameworks like Express, as well as Python with frameworks like Django and Flask, and PHP with Laravel. I am also adept at working with databases, including MySQL and MongoDB. I am highly experienced in Agile methodology and proficient in a wide range of tools and platforms. For instance, I have utilized JIRA, SCRUM, ASANA, and MONDAY for sprint planning and ticket management. In addition, I have employed HUBSTAFF and CLOCKIFY for time tracking, as well as INVISION, FIGMA, and SKETCH for design management. For repository management and CI/CD pipeline, I have utilized GITHUB, GITLAB, and BITBUCKET. The most important skill is that I have a deep understanding of software development principles, methodologies, and practices. My experience extends across a wide range of tools and frameworks, and I constantly explore the latest technologies to find innovative solutions to new challenges. Furthermore, I value relationships with my clients and prioritize close collaboration. I believe in working with clients as partners rather than simply being an implementation vendor. By actively listening to their needs, drawing upon my unique experiences, and offering tailored solutions, I strive to address their strategic goals effectively. I am truly passionate about creating exceptional software and I am committed to putting in the hard work necessary to achieve that. I am willing to take on tasks that others may find challenging, as I believe in going the extra mile to deliver high-quality results. Regarding availability, I am able to work full-time, dedicating 40+ hours per week, and I am comfortable adjusting my schedule to accommodate clients in different time zones. I aim to join a collaborative team that recognizes and values my expertise, while also allowing me to focus on my strongest skills and learn about the latest advancements in technology. My goal is to build a long-term career that fosters my professional growth and provides opportunities for continuous learning. Thank you for taking the time to read a little about myself. I look forward to working with you!
