Hello, I have many years experience developing Desktop and Web applications in various platforms, using languages like, C/C++, Java, JavaScript, Node.js and Go, and I am familiarized with a wide variety of integration APIs, which certainly include all major trading exchanges/Forex APIs.
Besides that, I worked with strong Cryptography in the past, using C/C++ and Java, as well as the most important cryptography libraries (CryptoPP, BouncyCastle, OpenSLL, to name a few) and devised a lot of Cryptography related products like CSP APIs, PKCS#11 APIs for smart cards and HSMs. I have also been working with criptocurrencies and Blockchain more recently.
I am sure I am able to deliver a product which is useful, powerful and perfect for your needs.
Regards,
Joeldo
