Roman B
About this gig
Looking for a developer who actually cares about your startup, not just the code?
I love startups. I build my own products, I think about users, marketing and how a product makes money. So when I build your MVP, I look at it like its my own: what will make people use it, what can wait for later, and what will help you get your first customers or investors.
For the past year Ive been building AI-powered products: web apps, landing pages, chatbots and Telegram bots with ChatGPT and Claude.
What I build:
- AI web app MVP: login, database, admin panel, AI features
- AI chatbots and assistants for your business
- Landing pages that turn visitors into users
- Automations, Stripe payments, API integrations
Stack: Next.js, Python, FastAPI, PostgreSQL, Claude and OpenAI APIs.
Before we write a single line of code, we talk about your idea, your users and your goals. Ill tell you honestly whats worth building first and what isnt.
You get a clear plan and price, regular updates and full source code.
Tell me about your idea. Im genuinely curious.

Developer focused on business results. I build high-converting landing pages, Python/FastAPI backends with PostgreSQL, AI chatbots, Telegram bots and automations that turn manual work into working solutions.
I work with AI tools every day, so I deliver faster without cutting corners. I also understand marketing and sales, which means I build what actually brings you clients, not just code that runs.
Fast replies, honest deadlines, open to long-term work. Tell me your idea.

FAQ
Do I need any technical knowledge?
No. You explain your idea in simple words, and I handle all the technical side. I’ll also explain every step so you always know what’s going on.
What do you need from me to start?
A short description of your idea, who your users are and any examples you like. If you’re not sure yet, we’ll figure it out together in a quick chat.
Who owns the code?
You do. After delivery you get the full source code and all rights to it
Who pays for AI and hosting?
The app runs on your own accounts (OpenAI or Anthropic, Vercel, Supabase), so you pay them directly. For an MVP this is usually very cheap or free at the start, and I’ll help you set everything up.
Can you add AI to my existing app?
Yes. The Basic package is made for that: one AI feature added to the app or website you already have.
What happens after delivery?
I’ll fix any bugs related to my work. For new features or ongoing changes you can add the 14 Days Support extra, or we can agree on a custom offer.
