    I have worked as both a Software Engineer and Business Analyst (requirements elicitation and documentation), on various projects, for over 9 years. Most of my work have been within the financial services domain. I have worked on web payment gateway integrations, business automation solutions, banking applications and more. I love to take on challenging projects. Good software, to me, can only be built by working from a user's perspective and maintaining strict compliance to software development best practices.
