Architecture discovery work
Mersad did a great job on our architecture discovery work. He took the time to understand the requirements, delivered a clear and well-structured assessment, and his recommendations were practical and easy to follow. Communication was responsive and professional throughout. A pleasure to work with, and I'd gladly engage him again.

🚀 AI-Accelerated Development (3x Faster Delivery)
I actively leverage modern AI development tools such as Cursor, Claude, and Codex to significantly accelerate development workflows, improve code quality, and reduce delivery timelines allowing clients to ship products faster without compromising stability or scalability.
This means:
✅ Faster feature delivery

I implement professional analytics and subscription infrastructure including:

With a proper analytics setup, you will clearly know:
✅ Where users come from (ads, organic, campaigns)
✅ Which campaigns generate paying users
✅ CPI, CAC, and user acquisition costs per country
✅ Conversion funnels & subscription performance
✅ ROI of marketing spend and scaling opportunities
