Background

About Daniel Heyde

I'm a Software Engineer with 4 years of professional experience at Amazon, preceded by 2 years as a junior developer. My work focuses on implementing and optimizing large-scale data processing systems and user-facing features. My technical foundation spans both backend and frontend development, with expertise in Kotlin, Java, TypeScript, and React, along with extensive experience in AWS cloud services. I've successfully led several high-impact initiatives, including the migration of billion-record datasets with stringent accuracy requirements and the integration of new book catalogs to anti-plagiarism systems protecting books daily for Kindle Direct Publishing's enterprise clients. I particularly enjoy optimizing system efficiency and user experience, having developed proof-of-concept solutions for both backend data processing and frontend performance improvements. Core competencies: • Backend Development (Kotlin, Java) • Frontend Development (TypeScript, React, Redux) • AWS Cloud Services (DynamoDB, Lambda, SQS, API Gateway) • Large-scale Data Processing & Migration • Performance Optimization • Containerization (Docker) Currently deepening my expertise in system design patterns and scalable architectures through continuous learning and practical application. I'm particularly interested in how large-scale systems maintain performance and reliability while handling complex operations at scale.
