Its good that you want to be a quant developer as there are very few locals who is very good in this field and there is demand for it. They need to be best of both worlds - Programming and Financial mathemathics. You also need to be proficient enough to challenge your business stakeholders (Quant guys) and speak on the same level with them to make your life easier. If money allows, best is to go for a Financial engineering masters on top of your current degree while working for an Investment Bank, preferably in the front office/Risk management as a Business Analyst/Analyst role to get yourself familiarise with the terms and jargons and also to fill up some experience in your resume.
