Available to hire
I am a versatile and impact-driven Full Stack & Data Engineer with a strong foundation in both product development and data-intensive systems. I have a proven track record building real-time GraphQL APIs, streaming data pipelines, and cloud-native architectures using AWS, Kafka, Docker, React, and Python.
Starting in front-end and UX, I evolved into backend engineering and data architecture—leading the design of global-scale solutions with sub-200ms latency, advanced ETL pipelines, and Gremlin-based graph systems. I enjoy bridging modern and legacy systems, promoting clean code, and mentoring cross-functional teams across international projects. I am AWS-certified and passionate about building performant, scalable, and user-centric software.
