Are you struggling to turn your app idea into a fully functional product without hiring a full development team? Is your Bubble app slow, buggy, or unresponsive on your mobile device? Do you feel stuck with workflows that don’t work as intended, or data structures that make your app hard to maintain?

I’m Muhammad Vardan, a Bubble.io developer with experience creating mobile and web apps for multiple industries, including AI tools, AI chatbots, food delivery, finance, ecommerce, team management, and SaaS platforms. I specialize in building apps from scratch, optimizing performance and workflows, integrating OpenAI, Stripe, and other APIs, and making apps mobile-responsive for a seamless user experience.

If any of this resonates with your needs, feel free to reach out! Your go-to Bubble developer, Muhammad Vardan P.S.

I build production-grade AI products for health and fitness companies. LLM/RAG, FastAPI, React, Flutter. Idea, or a broken MVP, to a real product that holds up. If you validated an idea and now need it built right, or you've got a vibe-coded MVP that's breaking and can't scale, that's exactly what I do. I take health and fitness AI products from concept to launch, the kind real users actually use every day. What I've shipped, all architected and built by me end to end: CuePilates, a full AI SaaS on Next.js, Supabase, Stripe and OpenAI, idea to launch in under a month. A clinical AI platform doctors use daily. DietTalk, live on the App Store and Google Play. How I work: a free call to scope it, then a working prototype of your core feature in about 2 weeks that you can use yourself, then the full build in phases where you see working software and approve each phase before you pay for it. Weekly demos, daily comms, clean handover so you own it. Secure, encrypted data handling, with production standards baked in: auth, payments, multi-tenant, scale. Not a demo that falls over at launch. If you're tired of cheap builds that leave you stuck, let's talk.

𝗬𝗼𝘂 𝗻𝗲𝗲𝗱 𝘀𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝘆𝗼𝘂𝗿 𝘁𝗲𝗮𝗺 𝗰𝗮𝗻 𝘁𝗿𝘂𝘀𝘁 𝘄𝗶𝘁𝗵 𝗹𝗶𝘃𝗲 𝗰𝘂𝘀𝘁𝗼𝗺𝗲𝗿𝘀, 𝗿𝗲𝗮𝗹 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀, 𝗮𝗻𝗱 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀-𝗰𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝘄𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀. Recently, a staffing company hired me to solve what looked like a verification problem. The original scope was simple: compare invoices against biweekly timesheets. But once I reviewed the actual workflow, the real problem became clear. The team was doing too much manual and unstandardized work before the verification step. The data was not always structured the same way, which created confusion, repeated checks, and too many edge cases for a verification tool to handle reliably. Instead of blindly building the first requested tool, I proposed a better automated workflow that standardized the process earlier and reduced the need for manual verification in the first place. The client saw the value immediately and asked us to move in that direction. That is how I work. I do not just build what is written in the task description. I look at the business process, identify where time and money are being wasted, and recommend the solution that actually makes sense.

𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I take on production software, AI-assisted MVP rebuilds, prototype-to-production SaaS platforms, workflow automation, internal tools, RAG systems, and full-stack web applications. I work well with both clear technical scopes and early-stage business problems, helping turn requirements, workflows, and ideas into practical software that can be built, launched, and maintained. I do not disappear mid-project. I communicate clearly, document important decisions, think through edge cases, and build with handoff in mind so your business is not dependent on me forever.

If any of this sounds relevant, send me a message or book a quick consultation call. I will review what you're building, tell you honestly whether I can help, and point out where I would improve the system or avoid unnecessary build cost.
