Pai Nuñeza

Senior Full-Stack Software Engineer with 11+ years of experience building and modernizing business-critical applications for international clients. I specialize in C#/.NET backend development, with strong experience in Vue.js, PHP, MySQL, SQL Server, API integrations, and legacy system modernization.

At Codev, I work on an international intellectual property management platform covering patents, trademarks, copyrights, renewals, due dates, and official fee workflows. I develop C#/.NET backend features for complex fee and due-date calculations, validation rules, and business processes, while also building frontend features with Vue.js.

As a Technical Lead Developer on a contract project, I led a team of four developers in rebuilding a legacy FoxPro desktop system as a PHP/MySQL web application. I also developed a C# WPF migration tool to convert legacy FoxPro DBF data into MySQL, helping support the transition to the new platform.

At Unient, I developed terminal operations applications for Australian clients, including integrations with Navis N4. I also built an internal timesheet and reporting platform used by approximately 100 employees, reducing the company's reliance on subscription-based HR tools.

My earlier experience includes developing the Health Watch application at Digital Excellence Group Cebu and supporting business applications at Alliance Software and M. Lhuillier Financial Services.

I'm interested in remote full-time, contract, and freelance opportunities with international teams, particularly in C#/.NET, backend, and full-stack development. I'm also open to relocation opportunities with visa sponsorship.
