    Hello! ๐Ÿ‘‹ I'm Stephan, a full stack developer and system administrator. I excel at building, installing and maintaining web and server applications. I've primarily been using React for building web apps, but I also have experience with other popular frontend frameworks such as Vue and Svelte. For server-side apps/scripts, I mainly use Node.js (TypeScript), but depending on the requirements, I may use Rust, Golang or C#. For desktop apps, I've been having a blast using Tauri. Electron is on my list too.

    I'm a Software enthusiast having around 8 years of development experience in Javascript and PHP. I started my journey by creating web applications and then I got used to working with other platforms like mobile and desktop. I'm also contributing to open-source libraries. In fact, I'm part of a few out there. I have a strong base in software development with an outstanding record in my curricula. In the past few years, I went through many technical challenges with remarkable performance. I'm pretty stronger in quickly getting up and running with new technologies, completed around 50+ projects with development expertise. I have vast experience in working with version control systems, specifically BitBucket and Git, Deployment pipes, Jenkins, and Travis CI. So far, I worked with Laravel, express.js, feather.js, socket.io, Vue.js, React.js, and React Native Web as a web stack. On the other hand in mobile, I am using Native Android, IOS, Flutter and React Native to develop applications. I'm addicted to clean workflow using testing frameworks like Karma, Mocha, and Tape. I'm also a part of a team creating a cross-platform desktop application in Electron.js. I'm having sharp skills in database systems including MySQL, NoSQL databases, and Graph databases like OrientDB and Neo4j. I write clean and maintainable code, build a foundation of projects and keep my clients updated about emerging technologies. I believe in "Growing up every day and starting with a fresh mind to let others grow up".

    "Antonis is a genius. His quality of work, after-sale service and clear explanations are impeccable. Overall, the best experience I have had on UpWork" "This is the kind of freelancer that makes me glad to have joined the platform. Antonis is a consummate professional. Expert, punctual, supportive, flexible, communicative. The money I spent on this contract was some of the best I've ever spent!" "Would highly recommend. ...job...handled immediately and exactly as I wanted" "One of the most reliable contractors I have worked with. " "This man is a magician with algorithms." "Antonis is absolutely brilliant. Really attentive and really quick to get things done." "Technically astute." "Excellent work. Quick turnaround. Great attitude." That's a summary of all different feedback on completed jobs up to date, and that's the quality of service I love to provide. Short CV: My professional experience spans over 20 years. In the last 10 years I have been working with Python, focusing on Data projects. I'm fluent with scrappers, pandas, numpy and pretty much any related library. Before that, there is one decade's data-analysis and programming experience. I had been working with data collecting and processing tasks of all sorts using Microsoft Excel, Google Sheets, VBA macros, VB, VBA, Python, custom scripts and professional licensed tools for web scraping (automated website reading), PDF scrapping, and editing, OCR (scrapping from image files, using Tesseract and Finereader), file/data management, 10.000+ entries on each project. Some jobs are: listing all the online offered lessons of high schools of the country, regional statistics jobs (for my country's Statistics Authority), automating daily or weekly tasks with extensive error handling, lead generation, scraping search engine results, social media scrapping and automating windows applications. I use professional tools and custom developed solutions. I can speak directly to API, or read/parse the HTML output. I deploy to cloud (I use Amazon Web Services) for scaling and to perform geo-related searches, completing huge jobs in a few hours. Tech Background: I have hands on professional experience with AWS (EC2, S3, SQS etc), Latex, Matlab. I have strong Physics and Mathematics background.

Web App Developer Hiring Guide

What is a web app developer?

A web app developer is a software engineering professional who builds, tests and maintains web applications that run on internet browsers. They specialize in creating user-friendly and high-performing web apps that meet specific business needs, such as e-commerce platforms, social media tools, and healthcare solutions. Web app developers use programming languages like Java, Swift, and Kotlin and leverage frameworks like React Native and Flutter to deliver cross-platform digital solutions.

Web app development also integrates mobile app development for platforms like iOS and Android. These experts balance front-end and back-end development, web design, and UI/UX principles to optimize user experience and ensure app functionality. Their skills are indispensable for startups, established businesses, and organizations looking to develop custom, high-quality web applications aligned with their business goals.

Why hire a web app developer?

Hiring a web app developer can significantly elevate your digital product's quality and functionality. With years of experience in app development services, these professionals ensure that your web application is not only user-friendly but also optimized for SEO and compatibility with iOS, Android, and other platforms.

A skilled development team brings know-how in frameworks, website development, Agile project management, and prototyping. They also handle complex tasks like API integrations, full-stack programming, and app design for digital products. Engaging the best app developers enables businesses to deliver innovative solutions and achieve their goals efficiently, whether for startups or larger enterprises.

How to hire web app developers

Hiring a web app developer on Upwork involves clear planning and careful selection. Follow these steps:

  • Define your project goals. Outline your business needs, target audience, and desired features, such as mobile application compatibility, app store optimization, or API integrations.
  • Draft a clear job post. Specify your requirements, including skills in mobile app development, frameworks like React Native and Flutter, and expertise in front-end, back-end, and full-stack development.
  • Review candidate profiles. Evaluate top app developers by their clutch ratings, portfolios, and years of experience in app development services and software engineering.
  • Interview candidates. Ask questions about their web development process, programming languages, and experience working on digital solutions for startups, e-commerce, and healthcare.
  • Collaborate effectively. Work with your development partner using Upworkโ€™s tools to streamline communication, project management, and timelines.

How to write a web app developer job post

A well-crafted job post can help attract high-quality web app developers. Hereโ€™s how to create one:

  • Use an engaging title. Titles like "Web App Developer for Cross-Platform Digital Product" or "React Native Programmer for High-Performing Web Application" work well.
  • Describe your project. Share details about your mobile app development company or business, your target audience, and your goals for the digital product.
  • Specify technical requirements. Include skills like mobile application development, frameworks (Flutter, React Native), and API know-how. Highlight the importance of UI/UX design, website design, and software engineering.
  • Outline deliverables. Detail expectations including prototyping, front-end and back-end development, or creating an SEO-optimized web app for an app store.
  • Include budget and timeline. Be transparent about project duration, whether for a short-term project or ongoing development projects.
