I am a Junior Full-Stack Developer specializing in React, Firebase, and JavaScript. I am passionate about creating high-performance web applications that provide exceptional user experiences.
My expertise includes developing responsive Single Page Applications (SPA), integrating real-time databases with Google Firestore, and automating business workflows using various APIs, including the Telegram Bot API. I focus on writing clean, maintainable code and delivering modern, "glassmorphism" inspired designs. I am dedicated to helping clients bring their digital ideas.
My Portfolio
FAQ
What types of APIs can you integrate into my website?
I can integrate a wide range of REST APIs and Webhooks, including messaging platforms like Telegram Bot API, database systems like Firebase Firestore, CRM tools, marketing automation trackers, and custom external web services.
Do I need to have a database or API keys ready before ordering?
It is preferred if you have the API documentation or keys available, but if you don't, no worries! I can guide you through the process or help you set up a secure backend infrastructure using Firebase Firestore from scratch.
How do the instant Telegram notifications work?
I will connect your web forms to a dedicated Telegram Bot. Whenever a user submits a booking or a lead form, the data is instantly routed via Fetch API to your phone as a private real-time notification.
Will my API integration be secure?
Yes, absolutely. I implement secure asynchronous data handling patterns using Async/Await structures, proper environment variables, and secure rules (like Firebase Security Rules) to prevent unauthorized access to your endpoints.
