About
I’m a full-stack developer with over 5 years of experience designing, building, and maintaining scalable web and mobile applications.
At Vehikl, I build enterprise-grade solutions end to end, implementing RESTful APIs, database architectures, and real-time features while following Test Driven Development to ensure reliability and clean, maintainable code.
Previously at Adknown, I developed and published over 20 mobile games, building reusable systems and optimizing development pipelines for speed and consistency.
I enjoy tackling complex technical challenges, improving developer workflows, and creating well-architected systems that perform at scale.
