01 / Softpoint Solutions
I deliver customized websites and end-to-end full-stack applications for commercial and media clients, translating business requirements into responsive, maintainable digital products.
I build business automation systems that reduce repetitive administrative work, while collaborating directly with clients and internal stakeholders to define features, resolve technical issues, and keep delivery aligned with practical business needs.
My involvement covers planning, development, API integration, testing, deployment, maintenance, and continuous improvement—including performance and database decisions that help products remain dependable as they grow.
02 / Knowles Corporation
I maintained and improved more than 500 WordPress training-course sites, keeping course pages, content structure, tables, imagery, and overall page quality accurate and consistent.
The role combined on-page SEO improvements with practical web-development support, including application features, defect resolution, performance, usability, testing, and debugging.
Working remotely with a Singapore-based cross-functional team strengthened how I translate business and technical requirements, document decisions, and manage development responsibilities within an established delivery process.
