Selected Production Software:

I have also worked on mobile payment/wallet applications, enterprise document-management portals, bakery management systems, WhatsApp Business API integrations, and Windows desktop utilities using C#/.NET.
How I Work:
I focus on understanding the business problem first, then translating it into clear technical requirements and a scalable solution.
My typical workflow is:
Discovery → Requirements → Architecture → UI/UX → Development → API Integration → Testing → Deployment → Continuous Improvement
I can work with detailed specifications or help structure an idea that is still at an early stage.
My strength is combining software development, product thinking, business analysis and technology leadership. I understand both the code and the business process behind it.
