I'm offering
I am an experienced Python developer, consultant and entrepreneur with a passion for building new systems.
My technical experience includes, but is not limited to, Flask, Django REST Framework, Bitcoin, Bootstrap, jQuery and machine learning. My career began in Dublin as a hedge fund accountant, performing data analysis and reconciliations. I used that experience and my coding abilities to automate similar accounting systems for HSBC in London. From there, I was internally headhunted for my knowledge of blockchain and became the product manager for their bitcoin custody project. Since then, I have launched an online business which involved, among many other things, designing and building a browser-based front-end and REST API back-end.
I have a proven track record of launching and managing projects, overseeing teams and improving the efficiency of everywhere I've worked.
