Paulus L.

Hi, I’m Loc, a mobile and web application developer with 10+ years of experience in software development. I help businesses build, customize, and deploy real working software, especially mobile apps, web systems, SaaS platforms, POS apps, inventory systems, booking systems, and business management tools. My main work includes: - iOS and Android mobile app development - Web application development - SaaS product development - POS, inventory, order, and booking systems - API integration and backend connection - App customization and white-label setup - App Store / Play Store deployment - Maintenance, bug fixing, and feature updates I can work on both new projects and existing source code. If you already have an app or system, I can help review the code, fix issues, add new features, improve the UI, connect APIs, and prepare it for production. I also have experience building ready-made business app foundations that can be customized for different businesses, such as retail stores, service businesses, pet spa/grooming shops, and small SaaS products. I focus on practical solutions: clean code, stable features, clear communication, and software that can actually be used by real customers. If you need a developer to build, customize, or deploy a mobile/web app, I can help you turn the idea into a working product.
