About Selvaraj
I am a Founder and hands-on CTO of YaazhTech Software Solutions UG, a Germany-registered technology company delivering enterprise-grade digital platforms across FinTech, banking, SaaS, and AI-driven domains. With over 14 years of experience, I specialize in designing, engineering, and scaling mission-critical systems in regulated and high-availability environments.
My core expertise lies in event-driven architecture, Apache Kafka (Confluent), Camunda 8 workflow automation, and Java/Spring Boot microservices. I have architected and led the development of credit card processing platforms, FX/FI trading systems, and risk analytics solutions, ensuring scalability, security, and compliance. In addition, I actively build AI-enabled SaaS platforms using Python-based LLM pipelines, intelligent automation frameworks, and cloud-native infrastructures on AWS and Azure.
What differentiates me is the combination of strategic leadership and hands-on technical execution. I remain deeply involved in architecture design, code reviews, system optimization, and DevOps strategy while guiding long-term product and technology roadmaps.
Through YaazhTech’s hybrid Germany–India delivery model, supported by a 50+ member offshore development center, I can quickly scale dedicated engineering teams for enterprise programs. This enables clients to benefit from German-based accountability and architecture leadership combined with cost-efficient, high-quality engineering capacity.
I am available for contract engagements as a Senior Developer, Technical Architect, or Fractional CTO, supporting organizations in modernizing legacy systems, building scalable microservices ecosystems, implementing workflow and streaming platforms, or developing AI-driven products.
My goal is to enable secure, scalable, and future-ready technology platforms that deliver measurable business impact.
