Rajesh Das

Hi, I’m Rajesh. I’ve been working in software development and architecture for about 20 years, mainly focused on building scalable backend systems, cloud native platforms, and enterprise applications.

My expertise is in Java, Spring, AWS, and Python, and I’ve designed and delivered solutions like pricing engines, risk analytics platforms, workflow automation, and large scale data processing systems. I have strong experience with microservices, event driven systems, and API integrations, along with containerization and CI/CD pipelines.

Over the years, I’ve worked extensively in the financial services domain—covering areas like FX, derivatives, compliance KYC/AML, and liquidity/risk management—so I’m used to solving complex problems with high performance and reliability requirements.

I also enjoy mentoring teams, modernizing legacy systems, and applying clean design principles like domain driven design to build resilient, future proof architectures.
