What I'm looking for

I am seeking a role that allows me to leverage my expertise in enterprise architecture and cloud solutions while fostering innovation and collaboration within a forward-thinking organization.

I am a TOGAF 10 certified Enterprise Architect with over 9 years of experience in designing and implementing solutions for SaaS. My expertise lies in translating complex business requirements into detailed UML models and solution designs, which are crucial for effective engineering implementation. I have a deep understanding of microservices and cloud architectures, enabling me to build scalable and performant distributed systems.

Throughout my career, I have worked extensively in the FinTech domain, particularly in banking and payments. I ensure that my solutions adhere to stringent security standards such as SOC2 and ISO 27001. My comprehensive technology stack includes open-source tools and frameworks like WSO2, Kafka, and Kubernetes, which I leverage to design secure, scalable, and integrated enterprise applications.

At Chakray Consultancy, I have successfully led projects that streamline operations and enhance customer experiences for clients like CRDB Bank. My role involves designing SaaS-compliant integration architectures and implementing secure microservices, ensuring that all solutions align with industry standards and best practices.
