Hi,
This seems like a very interesting offer. I am very experienced in react.js and redux. Have worked with mongo also and know most about it but am not a Mongo jedi as I can say I am with react.js and redux.
I usually climb fast to lead developer in past jobs I have taken because of my code quality and business decisions. I deliver very efficient and maintainable code that can save a lot of future headaches. This means that I often go for quality over speed. Let me clarify I am a very fast coder, and have good delivery dates, but I often prefer spending a little more time in planning and coding something that will save me time and effort in the future than delivering something fast and more sloppy.
I can, and have, worked with very fast deadlines where the client wants (needs more than wants) something delivered inhumanly fast but talked and decided before start so everyone is clear what the intention is and avoid misunderstandings later on.
I will deliver the most efficient, clean and maintainable code I possibly can (also well documented). Or, unless told otherwise, I can deliver functional code in very fast times (if it my choice always go with the former).
I am new to freelancer, but have worked in other platforms (mostly upwork).
Hopefully we can meet so I can show you work examples and talk about my experience or any other questions you might have.
Thank you very much for your time.
Kind Regards,
Carlos
