    📍I know how the Bubble.io app operates. 📍Did you know that Bubble scales your app automatically, even if it receives 500k page views daily? In such cases, your app will migrate to a Dedicated Cluster to handle the increased traffic, which is quite impressive, right? 📍However, Bubble.io utilizes a JSON-based declarative language to assemble apps. So, the way your app's flows are structured is crucial, whether they are backend or frontend workflows. It's essential for your existing or future app to be cost-effective, and capable of handling many users within a certain capacity while remaining easily maintainable as it grows. There shouldn’t be any unnecessary or redundant actions. So, let’s make sure your app follows best practices. 🗂️How I can help you: ⚙️I can develop any kind of app, but I will honestly tell you if I can't and provide other options. ⚙️I can integrate into your app any third-party services that exchange data using JSON language and adjust them with custom features, and plugins. ⚙️I can automate your manual workflows using Bubble.io or any other popular services. ⚙️I can review your app and give feedback on what possibly can be optimized or changed and implement them. 🗂️My primary focus areas include: 📌Building MVPs from scratch(No worries even if you don’t have any papers in hand). 📌Optimizing and refactoring existing apps to make them more resource-efficient. 📌Developing custom features with JavaScript (refactored, minified, and in some cases, obfuscated). 📌Creating custom private plugins (client-side/server-side). 📌Integrating with any third-party services, and modifying or creating database structures to handle their responses effectively. 🗂️In addition to the over +10 projects I've delivered, here are some experiences from collaborations with others: 💼 Streamlining Order Management: Automating Workflow and Notifications for a Major B2B Company's Application - Automated backend functions for a private B2B company's app, which has over 1000 retail suppliers as users, approximately 2,000,000 orders, around 4,000,000 in monthly workload usage, and more than 50 database tables. - The company previously changed order statuses manually for different case scenarios, leading to difficulties and extra work for the management staff. - I automated the workflow to enable automatic status changes of orders based on the situation, allowing users to work only with relevant data. - Developed notification functions that send SMS and Email depending on the order's status(overdue, canceled, moved). 📎Links: clicker.one 💼 Optimized Communications and Data Management for B2B Container Storage Company - Assisted a B2B Container Storage rental company that served over + 10,000 customers. - Integrated the RingCentral API and deployed it to production. - Added RingCentral Embeddable Telecommunication allowing users to make phone calls through the app. - Developed a custom JavaScript function to retrieve the user's phone session information and send it to the Bubble endpoint. - Developed a custom JavaScript function for Google Sheets to import data from the Bubble database into Google Sheets. 📎Links: mobilemod.com 💼Streamlining Data Management: Automating Google Sheets and Bubble.io Integration for a B2B Startup. - I automated the data exchange between Google Sheets and Bubble.io for a B2B startup. Previously, they had been manually modifying their static data by downloading and uploading CSV files, which was not cost-effective (incurring about 300-400k workloads every month) and time-consuming, as Bubble charges for such operations. - I developed functions that compare old and new sheets, updating only the existing rows. These rows are then validated and sent to an import sheet. Upon end-user confirmation, the data is sent to a Bubble.io endpoint, where the Bubble backend locates these rows in the app database and updates them. - This automation reduced the workload usage by 90%, as it checks and updates only the rows that are present in the entire table. 📎Links: Under NDA 🗂️Generally 📍I am a Low/No-code Engineer with 3 years of experience and 1 year in traditional development, passionate about solving problems and assisting others. 📍Delivered over 10 dynamic applications that cater to both B2B and B2C target audiences. 📍As an engineer, I focus on understanding how things work, not just on using them. For me not enough if things just work. It should be clean and refactored. 🗂️ Toolbox: 🧰No-code/Low-code Development Platforms: Bubble.io Xano Webflow Weweb.io 🧰Programming Languages and Frameworks: JavaScript VueJS Node.js HTML5/CSS3 🧰Cloud Computing Services: Google Cloud Platform Microsoft Azure AWS (Amazon Web Services)
