You have thought about technology for you business idea but haven't tested it yet. Proof of Concept testing reveals details you never might have thought of.
Example: I created an AI bot service that you can call with normal phone number. Possibility to test it for real reveals details about what is the actual quality of the AI chatbot.
Duration: Usually 1-2 days of development time but depends on the complexity of technology.
You have a business idea but you don't know how to build it. I can build a prototype for you so you can test it youself or with few test users.
Example: I have created a prototype for a company that wanted to build an information management system. This work was based on specification that was provided by the customer.
Duration: Usually 1-2 weeks of full-time development time but depends on the complexity of technology.
You have a rought MVP (Minimum Viable Product) built with Lovable, AI tools e.g. OpenAI customGPT or other tools. I can help you to build a minimum viable product so you can sell and test it with real users.
Example: I rewrote a minimum viable product (MVP) based on prototype that was built with AI tools. The prototype was usable but was overly complex and didn't have proper features (clear user flow, user management, security) to support real user testing so MVP was the clear next step that enabled founder to test it with real users.
Duration: Usually 1-4 weeks of full-time development time but depends on the complexity of technology and iterations based on user feedback. First iteration is done usually in days.
You might have already MVP or early phase product with real users. You want to have more real test users. Social media marketing is one of the easiest way to do that.
Example: I have worked before at Smartly.io helping advertisers to get results from their campaigns on Meta (Facebook, Instagram), TikTok and Google. I have helped many companies to grow their social media presence and acquire new users (customers).
Duration: Variable, depends on the complexity of the campaign and the budget.
Over the past 10+ years, I've worked across product development, engineering, and customer-focused roles, giving me a strong foundation to help turn early-stage ideas into real, testable products.
I've built proof of concepts that validate business ideas quickly, like an AI phonebot that lets users interact with a ChatGPT-style assistant through a standard phone call. Projects like this help uncover key limitations or unexpected user behavior early on, before investing in full-scale development.
I've developed prototypes for clients based on their business needs or specs, including internal tools like information management systems. I enjoy working with founders and teams to bring vague ideas to life, especially when there's a clear need for fast iteration and feedback.
I've also helped turn early prototypes into minimum viable products (MVPs), especially when prototypes built with AI tools or no-code platforms reach their limit. I focus on making things usable and testable, with clear user flows, real authentication, and enough polish to get in front of real users confidently.
Before my freelance work, I spent nearly a decade at Smartly.io, where I also supported social media marketing for global brands like Uber and Airbnb. That experience gave me a deep understanding of running data-driven campaigns, and I've continued helping startups and founders acquire users through platforms like Meta, TikTok, and Google.
"Olli was able to help me build a prototype further and learn in the process. That was exactly what I needed."
