Hi,
The project seems interesting and I must appreciate that you have clearly written down your requirements and have mentioned that there could be some additions and deletions. And hence I have quoted on the higher side because after discussion the project if the budget increases then its a waste of time for both the parties and if it comes down then it builds a good will.
I have gone through your requirements and would like to discuss further as design customization and adding tables in database and payment gateway integration is very generic and giving some time frame or budget without the details wont be appropriate.
I am full stack expert and have over 15 years of experience with deep understanding of Laravel, Python/Django ecosystem as well as frontend frameworks like ReactJS, VueJS and Angular. I also specialize in systems, DevOps, scaling, frontend development and multitude of frameworks, languages and systems.
My focus is on test driven development and employing CI/CD right from the start. Linux + Git + Docker + Vagrant are tools which I use day in and day out. Please go through my profile for more details. I am new at freelancer but have an impressive profile at up work dot com therefore no reviews here. I would like to explore the opportunity with you.
Looking forward to working with you.
Warm regards,
Divick
