    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!

    Electrical Engineer - Microcontrollers - PCB Design Now offering Tago.io integrations and Chirpstack integrations! It's confusing! Tags, entities, devices, authorizations, parsers, EUIs, etc. I'm not a true "expert" yet, but I can get things connected and working and I'm learning more every day. Also offering PCB design / rework / troubleshooting. Got 100 boards printed with with an error? Want to see if they can be saved from the trash bin? Also because it's so common - offering power supply design / troubleshooting. Regulator chip running too hot? Tripping thermal cutoff and causing power to flicker? Debating adding a large heatsink? And of course any general or specific questions about electronics, I take a "no stupid questions" approach as best I can. Thanks!
