Backend Software Engineer with Java

I'm a software engineer with 5+ years of experience. My expertise is in building robust, secure and scalable backend services in Java and Python. My primary domain of work is FinTech. Lately, to me, Tech doesn't feel as interesting as it was before corporate world, so I have been learning and using Go and Flutter for my personal projects. Am open to work in these technologies too. Prefer smaller team with high impact.
