About

As a Senior Full Stack Engineer with 7+ years of experience in building robust, scalable products for global FinTech leaders, I thrive on bridging technology and financial innovation to drive meaningful change. At Nium, I design and deliver microservices-driven, cloud-native cross-border payment solutions that empower businesses and individuals to transact seamlessly worldwide. My expertise spans Node.js, Go, AWS, Docker, and modern front-end frameworks like React, Vue and Angular. I have a proven track record in engineering high-performance systems, optimizing user experiences, and driving critical features from conception to deployment. I am passionate about leveraging the latest technologies to solve real-world problems, mentoring teams, and collaborating across disciplines to achieve ambitious goals. I also work as part of the Site Reliability Engineering (SRE) team, ensuring the reliability, resiliency, and stability of the products. An architect on the main thread and a developer on the worker thread. I’m guided by the principle “If it feels right, go for it,” while staying grounded in collaboration and letting the quality of my work speak for itself.
