Backend engineer specializing in scalable microservices and cloud solutions.
What I'm looking for
With over five years of experience in backend development, I specialize in creating high-performance and scalable microservices. My journey has led me to develop and deploy systems that cater to over 2 million users, efficiently handling more than 100 transactions per second. I pride myself on my strong problem-solving and analytical skills, which enable me to troubleshoot and debug effectively. Collaboration is key in my work, and I have a proven track record of driving project success through teamwork.
Currently, I am a Software Engineer at Sterling Bank, where I have enhanced system scalability by implementing a Kafka-based event-driven architecture, significantly reducing processing times. My role involves optimizing API response times and designing microservices that improve modularity and maintainability. I have also led a backend team in ensuring code quality and resolving post-go-live issues, achieving an impressive 99.9% system uptime.
Previously, as a Backend Engineer at DevHeit, I boosted system scalability and optimized cloud resource utilization. I am passionate about continuous learning and fostering a culture of knowledge sharing within my teams. My technical expertise spans various frameworks and tools, including Node.js, AWS, and Docker, which I leverage to deliver high-quality software solutions.
