Rajendrakumar Rajguru

I am Rajendrakumar Rajguru, presently situated in Auckland's CBD. I possess substantial software development expertise, actively coding in Go Lang, Java, Python, JavaScript (Node.js), and C++, alongside proficiency in frontend technologies such as Angular and React JS. My experience extends to cloud-native applications across diverse domains. I am well-versed in AWS and Azure platforms, showcasing proficiency in containerization, orchestration technologies, and DevOps tools. With a background in Agile, Waterfall, and DevOps methodologies, I've crafted robust architectures, built RESTful APIs, and applied design patterns. My career highlights include roles as Head of Engineering at Lemma and Principal Engineer at Xandr, where I led transformative initiatives in digital out-of-home advertising. Furthermore, I played a pivotal role in co-founding CarIQ, India's foremost connected car platform, where I was responsible for the architecture and coding of the CarIQ Platform. With robust problem-solving and analytical skills, I excel in leadership and mentoring roles. Certified as a CSPO®, CSM®, and PMP®, I'm excited to pursue fresh opportunities in software development and project management.  In addition to Auckland, I am also interested in opportunities in cities such as Wellington, Christchurch, Dunedin, and Hamilton that align with my profile. 

In my role at Lemma, I specialize in backend engineering for Digital Out-of-Home (DOOH) and Programmatic Digital Out-of-Home (PDOOH) projects, leveraging my strong foundation in technologies such as Golang, Python, MySQL, Apache Kafka, NoSQL databases, and Ansible. With a deep understanding of data structures, algorithms, and design principles, I tackle complex challenges in real-time bidding and ad-serving. During the development of our software platform, I applied advanced techniques in distributed systems to optimize content delivery across diverse DOOH networks. By utilizing Apache Kafka for real-time data streaming and NoSQL databases for scalable storage, we ensured efficient targeting and scheduling of ad content to maximize audience engagement. In collaboration with stakeholders in the AdTech industry, including advertising agencies and media buyers, I actively contributed to the design and implementation of features tailored to their specific needs. Through regular user testing and feedback loops, we refined our platform's usability and performance, integrating seamless customization and integration capabilities using Ansible for deployment automation. With a conscientious work ethic and strong attention to detail, I continuously strive to expand my knowledge in system design and large-scale distributed systems. My dedication to staying up-to-date on the latest developments in software architecture allows me to contribute effectively to the success of our projects, while my passion for exploring new challenges drives innovation and excellence in everything I do.
