Having dabbled in many facets of the tech industry, I'm a true Jack of All Trades. I've been trained as a systems engineer at Carnegie Mellon University and have a BS in Computer Science and Mechanical Engineering. The web world would call me a unicorn for my ability to take care of UI/UX design as well as the frontend and backend of the application, but that is only the tip of the iceberg in my capabilities and expertise. - Backend ✔ Python | Django | Flask ✔ Node.js ✔ Ruby on Rails ✔ASP.NET ✔PHP | WordPress | Laravel - Frontend ✔React | Angular | Vue ✔JavaScript (ES5/ES6) | TypeScript | CSS (CSS3, LESS/SCSS, SASS) | HTML5 - Database ✔MySQL | PostgreSQL | MS SQL Server | MongoDB - Cloud ✔Amazon Web Services | Google Cloud | Digital Ocean | Azure | Heroku - AI / OpenAI ✔ OpenAI API | ChatGPT | GPT-4 / GPT-4o ✔ AI Chatbot Development | AI Agents ✔ Prompt Engineering | RAG ✔ AI Automation | LLM Integration If you are looking for a technical architect for consultation or a full stack developer, who can help you with development, you have reached the right place. My goal here on Upwork is to make sure that my clients are 100% satisfied with the work that I perform and that their solutions are built to increase usability, revenues, and user experience. I can guarantee that the time you spend talking to me will be worth it!
