    My name is Wassim, and I have over 15 years of professional experience in web and mobile app development, marketing, and business. My clients range from single entrepreneurs to small, mid, large, and Fortune 500 corporations. I believe that building a successful application starts with understanding the needs behind building this application. Most developers jump straight to the technical side of things to perform what is needed while I research the best possible implementation to solve the client's problem. This approach has saved my clients and me tremendous efforts and time and has led to much better results. I work with so many technologies and programming languages, but the major projects I worked on via Upwork were related to: - Custom Web Apps - Shopify Web Design & Development - Chrome Extensions - Web Apps with NoCode (Bubble io, Webflow, and similar) - Squarespace websites creation (and similar services) - Google Sheet Automation and Scripting - API Integrations - Mobile app development with Flutter & Firebase/Firestore - Google Ads & Facebook Ads I am looking forward to hearing from you and learning more about your business and how my skills can help you achieve your goals.

    I started off my career 14 years ago and spent most of it developing software in Java. In the last couple years I have transitioned to Go as my primary language of choice. I enjoy working on many other programming languages and framework like NodeJS, Angular, React, Svelte and have dabbled a bit with Python here and there. My preferred database of choice is Postgres but I’ve worked with all types of relational databases and NoSQL databases. Although Java is still very much in my DNA, at the moment I am more focused on offers where Go is the primary language of choice. For me, Go offers a more pleasant developer experience. During my career, I’ve worked for large corporates and startups where I write the very first line of code helping entrepreneurs turn ideas into reality. Thank you for taking the time to read my bio and I look forward to working with you.

    Ionic, Capacitor, and Angular I have been on every step of the Ionic and Angular journey since 2015 as a developer using these tools to build cross-platform mobile apps and data-centric web apps. Ionic and Capacitor are an excellent combo for many businesses. These versions provide the best performance yet and, when used with Angular features, such as animations, results in a superb user experience. Angular along with RXJS is also a powerful platform for building web apps that either support Ionic applications or are stand-alone. Having the same developer working on both the Ionic mobile app and a supporting web app can make valuable business sense from efficiency and productivity standpoints. Cypress integration tests improve developer confidence in creating and releasing application updates. I can efficiently apply advanced Angular, Ionic, Capacitor capabilities to help you succeed with your project. My work can either be through hands-on development or with advising or coaching. I insist on being responsive to my clients and also providing clear communication and detailed documentation as it pertains to a project.
