Hey, I’m the founder of LogMyTrade, a trading journal SaaS built on Bubble. The product is already largely built and live, so I’m not looking for someone to build an app from scratch. I’m looking for a Bubble developer who can take over the existing application and continue developing it with me long-term. The work would include: • fixing bugs and existing issues • improving performance • developing new features • Bubble workflows/backend • database improvements • API integrations • maintaining the existing product If we work well together, I want this to become a long-term role with increasing responsibility and compensation as LogMyTrade grows. I’d like to start with a small paid task so both of us can see if we’re a good fit. If you're interested, please send me: 1. Your Bubble experience 2. 2–3 Bubble apps you've worked on 3. Any SaaS/API/backend experience 4. Your current availability 5. Your expected monthly compensation 6. Whether you're interested in a long-term arrangement

As a former Flutter and React Native specialist, my work in backend development and API integration perfectly aligns with your project requirements. I have a solid mastery level expertise in mobile app development using both native and cross-platform frameworks, including front-end and back-end technologies like RESTful APIs, GraphQL, Firebase integration, real-time features, and push notifications. I've also worked on complex projects involving automation and AI/LLM solutions where efficiency and performance were paramount - this translates directly to improving performance, developing new features, maintaining databases,and fixing bugs in your existing Bubble app. In addition to the above skills,I've also got extensive experience with WordPress CMS, web development on MERN stack, Python development for API Integrations and Automation (which would be very useful for script writing and traversing data pipelines). Every insight into these various technologis has honed a strong problem-solving aptitude in me. With an understanding of your intention for increasing responsibilities and compensation as your product grows,I am keen to commence by undertaking the small paid task suggested to further familiarize with your tasks before we embark on this journey together. Don't compromise for a second choice when you can entrust your baby to me for unmatched quality work and bug-free code. Let's discuss how I can augment your LogMyTrade through my Log2Jay tech expertise. Jay

Hi, LogMyTrade sounds like the kind of SaaS product I enjoy working on—an existing live application that needs steady improvement rather than a complete rebuild. My background is in SaaS development, backend systems, databases, API integrations, debugging, and performance optimisation. I’m comfortable taking ownership of an existing product, understanding its current workflows and data model, fixing issues carefully, and then extending it with new features without destabilising what already works. For Bubble specifically, I’m familiar with workflows, backend workflows, database structure, API Connector integrations, reusable elements, and performance considerations. I’d be comfortable starting with a small paid task so you can evaluate how I work before moving into a longer-term arrangement. I’m interested in a long-term collaboration and increasing responsibility as the product grows. One question: what is currently the biggest pain point in LogMyTrade—performance, workflow complexity, database structure, or unfinished features? Best regards, Jaroslav Caprata

LogMyTrade needs someone who can enter an existing live product, understand its workflows and data model, then improve it without destabilising current users. At Poundit, I maintained production applications with backend workflows, API integrations, databases, payments, and customer-facing features. My background is code-first full-stack development rather than a portfolio of dedicated Bubble builds, so I can’t honestly provide 2–3 Bubble app links. My strongest contribution would be diagnosing data and workflow bottlenecks, improving API design, reviewing privacy rules, and handling integrations or external services where Bubble needs a stronger backend. I’m comfortable starting with a contained paid task that has clear acceptance criteria, documenting every workflow or schema change, and building toward a long-term maintenance process. If deep Bubble experience is non-negotiable from day one, I may not be the right fit. Would you consider a developer with strong SaaS/backend experience but limited verifiable Bubble-specific work?

==== Hi - Albert here ==== "BUBBLE SAAS DEVELOPMENT" - you need ongoing development of the existing LogMyTrade product without disrupting its current workflows, data, or live users. I’d first understand the existing Bubble architecture, workflows, database structure, and API integrations before making changes. I can handle bug fixes, performance improvements, backend workflows, database updates, new features, and external API integrations while keeping changes modular and tested. I’m also open to starting with a small paid task before a longer-term arrangement. Can you share the Bubble application structure and the first paid task you’d like to use for evaluation? Looking forward to work with you

Hello, I’m a full-stack SaaS developer with 5+ years of experience working on existing applications, backend workflows, databases, APIs, performance improvements and ongoing feature development. I’m comfortable taking ownership of an already-live product like LogMyTrade rather than rebuilding it from scratch. I can work with Bubble workflows, database structures, backend logic, API integrations, bug fixing and performance optimization, while preserving the existing product architecture. I’m also comfortable understanding unfamiliar codebases, diagnosing issues and delivering changes through small, controlled tasks. I should be transparent that I cannot provide verified links to 2–3 specific Bubble apps or claim Bubble projects I cannot substantiate. Relevant SaaS/API examples can be shared where applicable. I’m available to start with the proposed paid task and am interested in a long-term arrangement. For ongoing work, my expected compensation can be discussed based on workload, responsibilities and the initial task results. I’m comfortable increasing responsibility as the product grows.

Hi, I am Muheebwa. I understand you need a Bubble developer to take over LogMyTrade, an existing live trading journal SaaS, and continue developing it with you long term, covering bug fixes, performance improvements, new features, Bubble workflows and backend, database improvements, and API integrations, starting at around 15 to 20 hours per week with a small paid trial task first. What usually matters most here is performance on an existing Bubble app, since Bubble workflows run sequentially on the server and a trading journal with years of trade entries will slow noticeably as the database grows, and the fix is usually restructuring the data types and search constraints rather than adding more front end logic. My approach would be to review the existing app, its data types, and privacy rules first, prioritise bug fixes and performance based on where the app slows and where records disagree, then take on new features and API integrations in agreed batches, with a small paid trial task to confirm fit before committing long term. I can share relevant Bubble and SaaS work, and I am interested in the long term arrangement. Looking forward to hearing from you.

With an extensive 9+ years acumen in web and mobile development, I am highly adept at leveraging technologies such as JavaScript, MySQL, PHP to build robust platforms. In particular, I have hands-on experience with Bubble and familiar with the domain of back-end development and database improvements which aligns directly with your needs. Moreover, I have created numerous SaaS applications giving me a profound understanding of your requirements. Additionally, my team and I have built several E-commerce CMS websites that exhibit peak performance even on high traffic. This implicates that your LogMyTrade platform will be developed, optimized, and maintained deftly irrespective of the increasing user base. This is further evidenced by my ability to solve both front-end and back-end issues proactively. I am eager to work with you on a long-term basis as I believe in developing relationships that evolve continuously along with mutual trust and growth. Starting off with a small paid task sounds ideal as it allows us to get a glimpse of our compatibility in terms of work style and efficiency. If chosen for this project, which we are fully equipped for, my team will ensure diligent and timely development along with providing you effective post-delivery support for three months. Let's convert your idea into reality together!

Hi there, For an already-live Bubble SaaS, I’d focus first on understanding the existing workflows, database structure, and performance bottlenecks so new development doesn’t create problems elsewhere. I can take ownership of ongoing fixes, backend workflows, database improvements, API integrations, and feature development as LogMyTrade evolves. I’m available for the proposed 15–20 hours/week and open to a long-term arrangement. Starting with a small paid task is also a good way to establish the workflow before expanding the responsibility. Send me the initial task and the relevant app details, and I’ll review the existing implementation and confirm the approach, availability, and monthly arrangement based on the actual workload.

Trading-journal apps on Bubble usually slow down in the same places as trade history grows: repeating groups that load every trade and then filter on the page, and nested searches. Stats get recalculated on every page load too. Moving those to server-side constraints and pre-computed stats fields usually makes the dashboard fast again and cuts workload units. Paid starter task (INR 7,500, 3 days): full audit of your data types, privacy rules, backend workflows and page performance, a prioritised list of issues, and fixes for the top bugs you pick, all in a dev version, deployed only after you approve. That shows you exactly how I work before we talk long-term. Yes to long-term. SaaS and API work (Stripe, broker/market-data APIs via the API Connector) is core for us; past client apps are under NDA so I can't share editor links. Available now, IST, replies within a few hours. Happy to agree a monthly retainer once the audit shows the real workload. Which broker or CSV imports does LogMyTrade support today? Aakaash

Bugs, performance, new features and API work on an existing live Bubble app, not a build-from-scratch job, understood. For the small paid task: I would start by auditing the current workflow structure and database schema to locate the specific bug or feature you flag, then implement and test the fix directly in a development version of the app before pushing to live. First checkpoint: a written summary of root cause plus the fix applied, delivered within 2 working days of getting access and a clear task description. Two first decisions: I would clone the app to a staging environment before touching anything, so live users are never affected while I work, and I would check whether the issue sits in workflow logic or in the database structure first, since that changes whether the fix is a quick patch or needs a data migration step. 1. Solid working knowledge of Bubble's workflow engine, database, plugins and API connector. 2. Built and maintained SaaS-style apps involving user accounts, dashboards and third-party API integrations. 3. Comfortable with REST APIs, backend workflows, scheduled workflows and data structure optimisation. 4. Available to start now. 5. Open to discussing monthly terms once the first task confirms fit. 6. Yes, interested in a long-term arrangement. I do not promise to guess the bug without seeing the app first. Can you share edit access and describe the specific issue you want fixed for this first task. Price: 4300 INR fixed · Timeline: 3 working days from access/brief Konrad
