You will get AI powered web application
Project details
I will build you an application on the backbone of GPT-3 or any other AI service like: stable diffusion or midjourney.
Have you played with ChatGPT or any other AI service and thought: "Wow I can use this to create an app"?
I'm here to help you with that. I will take your idea and transform it into a ready-to-market solution.
If you thought: "The results are great, but only sometimes. They are often completely bad." What we can do is help you fine-tune your model.
What is fine-tuning? It's a process, where we feed correct prompts and answers to the model as examples with enough correct data he will give us our desired result every time.
Solutions I can integrate:
• ChatGPT- "gpt-3.5 turbo" or any other OpenAI model.
• Midjourney.
• Stable diffusion.
• Whisper API
And many more... If you have an AI API that's not on this list don't worry. Ask me a question, whether I can integrate it or not and 99% of the time I will :)
Message me to get your individual quote on the project. I'm waiting to hear about your ideas!

I’m not just a developer. I’m your business partner. I solve problems beyond code.
My work resolves around 2 main concepts:
1. ROI - I focus on building apps that either save you time or generate real revenue. I have couple of free bonuses like messaging scripts tailored for you, ROI calculators and more!
2. Speed - Fast delivery is non-negotiable. If I miss our agreed timeline, you get your money back. No questions asked - 100% back. This is how much I value speed.
🟣 Why I'm different:
I think beyond code. I always ask: “What's the real goal behind your software?”
Many of my clients have worked with developers who were code-obsessed, leading to missed deadlines and lots of frustration.
I focus on the outcomes first, then build the solution that achieves it.
🆘 How can I help you?
1. Build you an app very fast that you can take to market and monetize.
2. Build a solution that saves you a ton of time on manual labour. Freeing up your/your teams time to do higher leverage tasks that GROW your business.

📈 Helped 50+ clients on Upwork build AI solutions and automate their workflows.
📈 Reached Top-rated plus on Upwork(top 3% of talent)
📈 100% 5-star reviews → ALL of my clients were happy with my work.
📈 Worked on projects for Fortune 500 companies.
📈 Marketed my own apps and built solutions for my business → I see the full picture, not just the code.
What you’ll get by working with me:
✅ Get progress updates DAILY.
✅ Free bonuses included: messaging scripts, ROI calculator and other Plug-and-play tools.
✅ Get your money back if I don’t deliver what you wanted OR in a timeline we agreed to.
I’ve worked with the following industries: Finance, Ecommerce, Agencies, Supply chain, Sales&Marketing, Coaching, Corporate training and more!
