Senior Bubble.io Developer Needed for Existing SaaS Platform

@Microlent

Bubble Expert Hi, I've reviewed your requirements carefully. Taking over an existing Bubble SaaS application requires more than adding new features. The first step is understanding the current architecture, identifying technical debt, and creating a clear roadmap to production. Our team has experience working on complex SaaS platforms, reviewing existing workflows, database structures, privacy rules, API integrations, responsive design, and performance optimization. We'll begin with a complete technical assessment, document our findings, prioritize issues, and provide a realistic estimate for the remaining development before continuing with feature enhancements. We've also worked on AI-powered and multi-user SaaS platforms, making us comfortable inheriting and scaling large applications built by other developers. For the initial assessment, I estimate 20 to 30 hours depending on the project's complexity. We are available 40+ hours per week for a long-term collaboration. One question before we begin: approximately how many database tables, workflows, and active users does the current Bubble application have? Looking forward to discussing the project. Rajesh

Hi there, Bubble Expert I will review your existing Bubble app against the HTML prototype, rebuild the selected pages with responsive design, and tighten UI consistency across the platform. The first milestone is a clear, well-scoped handoff, and I have taken over Bubble projects like this before where the original developer moved on. On a similar SaaS takeover, I started by auditing the database structure and workflows for hidden dependencies before touching any pages, which prevented breaking things downstream. I will do the same here. Questions: 1) How many pages from the HTML prototype are included in this first milestone? 2) Are there any third-party API integrations already in place that I should be aware of during the review? I am happy to share relevant Bubble project examples once we connect. Looking forward to talking through the details. Kamran

I SPECIALIZE IN TAKING OVER EXISTING PROJECTS, CLEANING THEM UP, AND TURNING THEM INTO STABLE PRODUCTS THAT CAN KEEP GROWING WITHOUT REBUILDING FROM SCRATCH. Hello! Bubble Expert. What caught my attention is that you're not looking for someone to start over, you're looking for someone who can understand an existing Bubble application, compare it against a documented vision, and move it forward without introducing technical debt. That's exactly how I approach inherited projects. I would begin by reviewing the current Bubble application alongside your HTML prototype, technical documentation, and roadmap to identify gaps, inconsistencies, and workflow issues. Then I would rebuild the selected prototype pages with fully responsive Bubble layouts while keeping the design consistent across the platform. During implementation, I would clean up workflows, optimize database structure where needed, improve performance, and fix related bugs without disrupting existing functionality. I'll also document any technical concerns, limitations, or future risks so there are no surprises as development continues. My goal for the first milestone is not only to deliver the requested pages, but also to leave the project in a cleaner and more maintainable state for the next phase. Warm regards, Yulius Mayoru

Hi, Bubble Expert. We will review your existing Bubble app against the HTML prototype, rebuild the selected pages with responsive design, and resolve UI inconsistencies and workflow bugs for your first milestone. When inheriting a Bubble project, we start with a full audit of the database schema and workflow logic. This reveals orphaned workflows and inefficient searches early, so we fix performance issues before they compound. A couple of quick things to confirm: 1) How many pages from the HTML prototype are included in this first milestone? 2) Are there any active API integrations we should be aware of before diving in? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to discussing further. Best regards, Faizan

Bubble Expert Taking over an existing Bubble SaaS is usually less about “building pages” and more about understanding what is already there before changing workflows, database structure, or responsive behavior. For your first milestone, I’d approach it in a very structured way: review the current Bubble app, compare it against the HTML prototype and documentation, rebuild the selected prototype pages in Bubble, and clean up UI/workflow issues as they appear. A few things I’d focus on first: * Review database structure, option sets, workflows, reusable elements, and API connections. * Compare existing Bubble screens against the HTML prototype and specs. * Rebuild selected pages with responsive behavior, not just visual matching. * Fix bugs tied to workflows, UI consistency, and data handling. * Flag any technical blockers before they become long-term issues. Relevant details: * Bubble experience: [ADD YEARS] * Bubble project links: [ADD LINKS] * Inherited project examples: [ADD 1–2 EXAMPLES] * Hourly rate: $50/hr * Weekly availability: 30 hours/week

Bubble Expert ⭐ Hi, I can help take over your existing Bubble SaaS platform, review it against the HTML prototype and documentation, fix current workflow/UI issues, and complete the first milestone in a clean, maintainable way. I understand the main challenge here is not building from zero, but entering an existing Bubble app carefully: understanding the database structure, workflows, responsive behavior, API connections, and current bugs before making changes. That is important so the first milestone is completed without creating new technical debt. I have experience working with existing SaaS platforms, database logic, workflows, API integrations, responsive UI fixes, performance improvements, and continuing projects started by other developers. My approach would be to first compare the Bubble app with your prototype/docs, then prioritize bugs and missing milestone items, improve UI consistency, test workflows, and provide clear recommendations for the next development phases. I’m available for long-term collaboration if the first milestone goes well, and I can work with documentation, roadmaps, and structured milestones. Hourly rate: 15-20 Weekly availability: 40hr Best regards, Hugo

Bubble Expert Taking over an existing Bubble SaaS is less about adding features and more about understanding the architecture before making changes that could create technical debt. I'd begin with a structured audit of the database, workflows, backend logic, privacy rules, reusable elements, responsiveness, and API integrations. The biggest challenge is identifying hidden workflow bottlenecks and security gaps without disrupting existing functionality, so I'd document findings, prioritize fixes, and provide a realistic roadmap to production. Once the assessment is complete, I can continue with feature development, performance optimization, and code cleanup while keeping the application maintainable as it grows. Please attach relevant Bubble projects you've built or inherited to strengthen your proposal. Can you share roughly how many database tables, workflows, and API integrations the current application contains?

@arturg6

Hello, first development milestone – reviewing the existing Bubble app and rebuilding the HTML prototype pages in Bubble with responsive design. I'll set up Bubble's API Connector with background workflows so page loads stay under 200 ms, and audit privacy rules to guarantee each SaaS tenant sees only its own data – a common blocker for multi‑tenant platforms. I'll also use conditional visibility and 100 % container widths to ensure mobile breakpoints render cleanly. Do you have a target date for delivering the first milestone? Looking forward to working with you. Artur Giżycki

@remonk0

Bubble Expert Hi, This sounds like the right stage to bring in someone who can assess the Bubble app carefully before adding more features. When a SaaS platform has already been built for several months, the first priority should be understanding the database, workflows, privacy rules, reusable elements, and performance risks before making new changes. I have experience working on Bubble applications with complex workflows, backend logic, API integrations, user roles, dashboards, responsive layouts, and SaaS-style structures. I’m also comfortable taking over projects started by another developer, identifying what is solid, what needs refactoring, and what may block production readiness. For the initial assessment, I would review the database structure, privacy/security setup, workflow logic, responsive behavior, reusable elements, API connections, and performance bottlenecks. Then I’d provide a clear report with bugs found, recommended fixes, production-readiness gaps, and an estimate for the remaining work. After that, I’d be happy to continue with stabilization, feature development, optimization, and long-term platform support. Remon

Bubble Expert. I am a lead developer with 9 years of experience, and I specialize in stabilizing complex SaaS platforms built on Bubble. Inherited projects often suffer from bloated workflow trees and poorly structured database relationships that cause latency as user counts grow. I know how to audit these systems to ensure privacy rules are ironclad and the architecture is ready for production scaling. I lead an in house team of 50 developers, which means you get stable, professional support that does not vanish mid project. I focus on identifying technical debt early so your roadmap remains predictable and secure. • SaaS Booking Management | https://www.freelancer.com/portfolio-items/11252501-ai-booking-management-system I took over this platform mid development, optimized the database, and resolved critical workflow bottlenecks. • Scalable Education Platform | https://www.freelancer.com/portfolio-items/11237894-scalable-online-exam-platform This required managing large datasets and complex multi user logic to ensure system stability under load. • Frontend: Bubble responsive engine • Backend: Bubble workflow logic and API connector • Database: Bubble integrated database with optimized privacy rules • Other: Custom API integrations and performance auditing I focus on clean, scalable architecture to keep your application fast and maintainable as you grow. I can start immediately and would be happy to discuss your project in more detail before we kick off.
