    With over 12 years of experience in full-stack development, I have successfully built 20+ projects at a range of companies. My expertise spans frontend and backend development, cloud infrastructure, API integration, and UI/UX design, ensuring end-to-end solutions that drive efficiency and growth. On the frontend, I work with JavaScript and TypeScript, leveraging frameworks like React, Angular, Vue.js, Next.js, and Nuxt.js to create dynamic, responsive user interfaces. State management is streamlined using Redux, Vuex, RxJS, and NgRX, while UI/UX is enhanced with Bootstrap, Material UI, Tailwind CSS, SASS/SCSS, and styled-components. For component-driven development and design consistency, I incorporate Storybook. On the backend, I develop scalable and efficient server-side applications using Node.js, Express.js, Nest.js, Python, Django, and Java. I ensure robust data handling with PostgreSQL, MongoDB, and MySQL, utilizing ORM frameworks to optimize database interactions. Testing and quality assurance are integral to my workflow, employing Jest, Enzyme, Cypress, and React-Testing Library to maintain high code standards through TDD and BDD practices. Cloud infrastructure plays a crucial role in my development approach, with hands-on experience in AWS, Azure, and GCP for scalable deployment and secure application management. My deep understanding of object-oriented programming (OOP) allows me to architect well-structured, maintainable applications that align with best practices. I am committed to delivering clean, optimized, and maintainable code, ensuring that each project is built for scalability, performance, and user satisfaction. Whether developing complex enterprise applications, interactive user interfaces, or cloud-native solutions, I bring a results-driven approach to every project.

    90% of Web/App/Mobile Projects FAIL. Don’t be one of them. ✌🏻 Hiring us is like a breath of fresh air .. I can help you navigate through these treacherous waters to success. Do you want to shortcut your development journey and make it a more seamless ride? If so read on. All project management and product development is done by us here in Melbourne and I will make your project complete on time and budget, so you can focus on what matters. We leverage global talent to help us complete other aspects of projects, so we can help keep the cost down and the quality up. I have more than 20 years of experience in industry both technically and as a business person. I know about the heartache and pain that goes into making a successful website or application. If you are going to spend $1000s of dollars and time on a project please make sure you investigate all your options. Leverage my experience and knowledge to create that perfect website, web or mobile application. I have done projects and have experience in: 1. Building websites and apps in PHP - Frameworks such as Code Igniter, CAKE - CMS Like Wordpress 2. Python & Django 3. Javascript 4. AWS - S3, SES, Lambda, EC2 5. Microsoft Azure 6. Google Cloud Platform 7. Major Ecommerce platforms - Shopify, Bigcommerce, Weebly, Woocommerce, Opencart, Magento to name a few 8. Linux Platforms - Ubuntu, Centos & Free BSD 9. Agile Software Development 10. We use Jira for all our projects 11. API Integrations - both web and mobile 12. Medical Integrations - HL7 and Medicare 13. Hubspot API Intergations 14. Data Scraping off platforms that don't support APIs. 15. Docker Support and Installation Reasons Why Projects Fail: 1. If you are doing a project for the 1st time you may not understand what technology platform to select and this could be catastrophic down the road. 2. Your estimate of time and effort required might not be realistic and some developers will say yes to anything and may not be able to deliver. 3. You select contractors based purely on price not communication abilities or experience, I personally test and vet all the contractors and employees that work on my projects. 4. Timelines are critical and through my experience I am able to formulate these and get the correct number of resources onto the job, whilst maintaining budget 5. What looks simple could be complex indeed or they might be a better, faster and cheaper way to do these tasks, I can definitely work them out for you. 6. Some contractors have really poor internet connections and equipment this could hamper your project, also I advise on how contractors could speed up backups, downloads etc to save you money and time. 7. Developers rarely test work, I continuously test their work and have a methodical way of testing every part of the product. 8. Finally and most importantly most developers will develop you a pretty site, I consult with you on how it can be made for calls to action, getting names, phone numbers, emails to turn your site or app into a marketing machine, as I have a lot of experience with web marketing. So why hire me? Would you rather spend 6 months on a project that could take 3 months or less and cost less? I have personally worked on large scale web app projects in different platforms as well as built many Wordpress sites. I have also worked with mobile apps and understand aspects of how these should be developed. Most importantly I can help you work on how to market your websites, apps and mobile apps as what the point in developing these if you can’t make any money on them? I am available via voice and video chat via Zoom, Cisco Webex, Skype or any other platform you like.

    I am an ISTQB Foundation-certified Testing professional who worked across various testing phases like requirement gathering, authoring test cases, test execution, scheduling overnight runs, artifacts preparation, test automation, defect management, test data preparation, and status reporting. I have very good test automation experience in Salesforce Application. I have built a full regression suite using WebDriverIO (Node-JS), bit-bucket pipeline, Lamdatest (Selenium Grid). I performed cross-browser testing and managed the overnight test execution in Lambda test in multiple platforms. I also worked on a payment platform testing with levypay.com. I have solely created test plan and test cases. I have also prepared the final Test Summary Report for the client. I have suggested enhancements to levy pay portal to strengthen the platform. I have successfully carried out testing for a few projects which involves various type of business-like food online ordering (Hungry Jacks), Gaming Mobile Application in Android and iOS. I also have tested CRM-based projects individually with minimal supervision. I have created test cases and executed test cases for the enhancements of the CRM Application. I have demonstrated my quick learning skills when I handled two projects during my internship at Genix Ventures. I have automated order processing and admin features for the portal prstx using Selenium. I have also provided enhancements for the portal to enhance the customer experience.

    My name is Omar Hassoun. I have been working as a web developer since 2014; I am experienced in Core PHP, MVC, OOP, PDO, MySQL, JavaScript. JQuery, HTML, CSS, Bootstrap, AJAX and JSON. I develop my own techniques and strategies using OOP and MVC model to make the developing process easier, clearer, and secure. I enhance the design in a way that meets clients' needs, using HTML5, CSS3, JQuery, JS, and AJAX taking into account SEO considerations. For responsive design, I use my own media query framework and bootstrap according to clients' needs. To improve the performance and loading speed, I used to organize and minimize files' sizes, executing time of scripts, SQL queries, and sometimes applying some functions after loading using AJAX to enhance speed score. I am always working in an organized manner to make further improvements more easily.
