Paulo Arceno

I am a passionate and results-driven Software Engineer with over 5 years of experience in designing and delivering scalable, high-impact backend systems. My expertise lies in Ruby on Rails, React, and API development, where I have a strong track record of translating complex business needs into robust, production-ready solutions. I thrive in fast-paced, collaborative environments, bringing a proactive mindset and solid problem-solving skills to every project.

In my recent role at PayMongo, Inc., I designed and built core backend services that powered mission-critical payment flows for thousands of businesses. I spearheaded the development of a Recurring Payments system, significantly increasing the Total Payment Volume. My contributions also included leading the integration of Mastercard Click to Pay, making PayMongo one of the first companies in the Philippines to support this feature, thereby enhancing user experience. I am committed to delivering high-quality software and have a proven ability to resolve high-priority production issues under tight deadlines.

As a Freelance Software Engineer, I have developed dynamic web app features using Next.js and designed asynchronous background tasks for AI file analysis. My experience at Trend Micro involved building backend components for a high-throughput file processing pipeline, where I optimized performance through multithreading and asynchronous programming. I am dedicated to continuous learning and improvement, always seeking to enhance my skills and contribute to innovative projects.
