You will get an AI-powered custom web application MVP ready for market launch
Project details
Stop Guessing. Start Testing. Get a Functional MVP Core for $5.
Most developers ask for thousands before you see anything real. I do the opposite.
Using a high-speed AI-assisted development workflow, I’ll build the foundational 60–90% core of your web application — so you can actually see, test, and validate your idea before committing to full development.
What you get in the first phase (48–72 hours):
• A working MVP foundation — not a mockup, but a real, testable web app
• Clean, modern UI with your branding (colors, fonts, basic layout)
• Initial AI functionality (if required for your idea)
Why $5?
This is a low-risk entry point to prove execution speed and quality.
Instead of asking you to “trust me,” I show you a working product first.
After this phase, we can move to the final 10–40%:
advanced features, integrations (payments, APIs), scaling, and full production launch.
Important:
This offer is designed for founders who want to validate ideas quickly — not for full production systems in a single step.
If you want to see your idea come to life fast and make decisions based on a real product — click “Buy Now” and let’s start.

Hi, I’m Sergey — I specialize in delivering SaaS apps consistently focused on earning revenue.
I specialize in combining React / Next.js frontends with Python (FastAPI) backends to deliver complete, production-ready products — not just isolated features.
𝗜𝗻𝘃𝗶𝘁𝗲 𝗺𝗲 𝘁𝗼 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗼𝗿 𝘀𝗲𝗻𝗱 𝗮 𝗺𝗲𝘀𝘀𝗮𝗴𝗲.
If it’s a good fit, we can quickly align on scope and move fast.
🗣 Charles Brun - 𝗛𝗲𝗮𝗱 𝗼𝗳 𝗦𝗮𝗹𝗲𝘀, Entrepreneur
❝Sergey is a highly dedicated and reliable developer who brings strong initiative and persistence to every project. While working on Wizardly, he consistently tackled challenges head-on, found solutions, and stayed fully committed without ever watching the clock. He’s easy to work with, and genuinely cares about delivering results. I’d highly recommend Sergey. ❞
I specialize in guiding the app development process to maximize revenue potential while keeping costs under control—and helping you avoid the common pitfalls that derail most SaaS products.
Client Outcome Examples:
⚡ tubenichefinder.ai (5-Figure Acquisition - Concept-To-Live in 2 Months)
⚡ woodle-auto.net (5-Figure Annual Recurring Revenue - ARR)
⚡ amy.ai - (5-Figure Annual Recurring Revenue)
My support is based on hard-won successes built through more than a 7 of SaaS app obsession.
💡 What I help clients with:
⚡ Building full SaaS MVPs (frontend + backend)
⚡ Designing and developing FastAPI backends & APIs
⚡ Creating modern, responsive React / Next.js interfaces
⚡ Integrating AI tools, APIs, and third-party services
⚡ Improving performance, UX, and scalability
🎯 Typical clients:
☑️ Founders launching MVPs
☑️ Startups needing fast development cycles
☑️ Teams scaling SaaS products
☑️ Businesses automating workflows with Python
🧠 My approach:
Most developers either focus on frontend or backend.
I focus on how everything works together:
→ Fast UI + fast API = better user experience
→ Clean architecture = easier scaling
→ Smart trade-offs = faster time to market
The goal is not just to build — but to ship something that works and grows.
🚀 Every project includes:
📱 Responsive UI (Desktop / Mobile)
⚡ Fast APIs with FastAPI (async, scalable)
🧩 Clean architecture (frontend + backend)
🔌 API integrations (REST / AI / third-party)
🛠 Maintainable, production-ready code
🧪 Testing & QA basics
Thanks for taking the time to learn more about me. Invite me to your project or send me a direct message if you’re interested in working together. Talk soon!
