Code -> Play guitar -> Draw -> Play -> Sing -> Repeat

I'm all about building scalable and robust applications, bringing over 5+ years of experience. As a Backend Software Engineer, I've driven efficiency improvements of up to 60%, thanks to my expertise in Go and JavaScript. In my current role at Cudium, as a Senior Software Engineer, I've integrated backend systems with third-party applications, boosting our understanding of user engagement by 85%. Beyond coding, I enjoy mentoring, documentation, and spearheading security features for a safer application. During my internship at Nomba, I honed skills in Node JS, MongoDB, and Java, improving data persistence for vendor services and reducing fraudulent transactions by over 60%. At Kudi.ai, I implemented transactional features, optimized legacy code, and crafted an account balance slack notification service, boosting stakeholder efficiency by 75%. At Airgateway, I was focused on enhancing support for agencies in their airline bookings. When not in the tech world, you'll find me strumming a guitar, hitting the dance floor, or belting out a tune. Let's connect over coffee and chat about tech, career journeys, or the latest music trends! I'm always looking to expand my network. Feel free to reach out at caleberioluwa@gmail.com
