IMPORTANT: Every client has unique needs - please reach out via Upwork Chat to discuss first before placing an order
Have a raw concept or a complex business problem, but unsure how to translate it into a functional product? I de-risk your investment by providing a structured Discovery Phase that bridges the gap between a "big idea" and a market-ready technical reality.
What You’ll Get?
• Product Strategy: Vision, goals, and a high-level feature breakdown.
• Technical Architecture: A defined tech stack and solution design.
• Risk Assessment: Identification of the roadblocks before they cost you money.
• Execution Roadmap: A detailed Work Breakdown Structure and timeline.
• Team & Budget Estimates: Clarity on the investment required.
• UI/UX Concepts: Visual design directions for the key screens.
The duration depends on the project’s complexity:
1 Week: For quick alignment and high-level requirements.
2–3 Weeks: To test feasibility and refine the concept.
4–6 Weeks: Deep dive into architecture, design, and full implementation plans.
You will get a development-ready plan. We move straight into implementation with reduced risk, aligned priorities, and a clear path to launch.

30 minute consultation
I had a wonderful experience working with Oleksandr's team during the consultation for an AI voice agent. He was able to answer all of my questions in depth, offering useful insights and recommendations that were specific to my business. Oleksandr's knowledge about AI agents is extensive, to say the least, and it is valuable for anyone who needs advice on AI and LLM integration. It was also great to see solid expertise with platforms such as ElevenLabs, Twilio, and Azure, which are essential in developing effective AI voice agent solutions.
Oleksandr is a good communicator, making complex topics sound simple, and was very collaborative in our work together. I also appreciate his focus on quality and solution-oriented mindset. Will certainly reach out later, when it comes to implementation!
