I am a Software Architect responsible for code review, system architecture and development of core system features. I regularly hold presentations and training sessions for local as well as international teams of developers. I am an advocate of iterative and incremental development as part of Agile methodology, and promoter of Kanban to facilitate transparency within team work. I have completed Lean training and implemented Lean principles into my workplace. Following Domain Driven Design paradigms, I have re-designed and gradually refactored in-house ERP systems as well as transitioned a business from a legacy e-commerce platform to Magento integrated with warehouse management system. In the past I have introduced modern software architecture techniques and principles such as SOLID Principles, High Cohesion, Loose Coupling, Dependency Inversion which improved code quality and system reliability - emphasised together with Continuous Delivery and Unit Testing. In 2012, I was appointed by my employer to lead a local team of software developers at our Manilla office in the Philippines. My objective was to improve team performance through training and leading. I successfully managed to implement agile practices which allowed the team to become a recognised part of our international operations.
