Profile bio

About Jefferson Oña

With an engineer's degree in systems engineering. I am a full stack developer at Rankmi, a leading company in talent management and performance evaluation solutions. At Rankmi, I leverage my Python, IA, and Docker skills to create and maintain web applications that use AI-powered chatbots, REST APIs, and event queue systems to provide clearer responses, improved decision-making, and faster processing of forms and reports. Previously, I worked as a software developer at ioet Inc. for two years, where I led the development of a web application to track employee performance and bonuses, developed new controls to pass American audits, and decoupled a purchase order process from a monolithic system. I enjoy working with agile methodologies, collaborating with cross-functional teams, and solving complex problems with innovative solutions. My goal is to keep learning and growing as a developer and to deliver high-quality products that meet the needs and expectations of the clients.
