I am a Full-Stack Java Developer with 6 years of professional experience building business-critical systems, including accounting platforms, loan systems, eWallet applications, internal management systems, and process automation tools.
My strongest expertise is in Java, Spring Boot, REST APIs, SQL, backend development, and full-stack business applications. I also have a background in accounting and finance, which helps me understand business logic, financial workflows, reporting, billing, and automation requirements more deeply than a typical developer.
Here are some of the solutions I have worked on:
1.) Built an accounting system from scratch, including journal entries, expenses, payables, profit and loss statements, billing, and financial reporting
2.) Migrated a legacy FoxPro system into a Java-based business core system
3.) Developed and improved loan processing systems, reducing processing time from 5 days to 1 day
4.) Automated tax filing workflows, including BIR DAT file generation and validation
5.) Contributed to a multi-currency eWallet mobile app and internal casino management system
6.) Built backend APIs, frontend screens, database processes, reports, and automation tools
I can help you with:
Java and Spring Boot backend development
REST API development and integration
Full-stack web application development
SQL database design and optimization
Accounting, finance, loan, and business automation systems
Legacy system migration
Bug fixing, code review, documentation, and system improvements
I focus on building systems that are clean, reliable, maintainable, and aligned with real business operations. My goal is not only to write code, but to help your business reduce manual work, improve accuracy, and create scalable digital solutions.
