Mohammed Yasir

I am a Senior Java Developer with over nine years of experience building scalable fintech and SaaS solutions using Java, Spring Boot, microservices, AWS, and Kafka. I focus on clean code, distributed systems, and delivering measurable business impact.

I architected and migrated monoliths to microservices on AWS, improving throughput by 35%, reducing latency by 20%, and enabling substantial cost savings. I designed secure RESTful APIs and payment integrations that improved interoperability and reduced integration time.

I lead and mentor engineering teams, automated CI/CD pipelines to accelerate releases, and enforced rigorous code review practices that reduced production defects by 25%. My projects include a fraud detection engine that cut fraudulent transactions by 30%, saving $500K annually.

I contribute to open source (Apache Kafka optimizations) and prioritize performance, reliability, and security while collaborating with cross-functional teams to deliver features faster and with higher quality.
