Hi,
my name is Esteban Salpeter and I'm an experienced developer, with many years on different platforms. You can check out my portfolio to view some of my work.
Your requirement is very clear, so the webapp can be done easily. I use web2py for its simplicity, state-of-the-art and great looks.
I am proficient in accounting from Universidad de Buenos Aires.
I've also designed and deployed an accounting + ERP system with MS Access and SQLServer, which I'm currently migrating to the cloud.
Feel free to ask me any questions before contracting, I'll be glad to chat with you.
Hoping to start working together soon,
Best regards,
Esteban
