FAQ
What technologies do you use for development?
I specialize in core web technologies to ensure maximum performance. For frontend logic and interactivity, I use JavaScript (ES6+). For backend and data management, I work with SQL (MySQL, PostgreSQL).
Is database architecture included in every package?
Yes. A robust web application requires a solid data foundation. I include Database Design (ERD) and Schema Normalization in all my packages. This ensures that your system is not only functional today but also scalable and easy to maintain as your data grows.
Do you provide support after the project is delivered?
Absolutely. I provide a technical support period (7 to 14 days depending on the package) to ensure everything runs smoothly. If you encounter any bugs or logical errors related to the original scope of work, I will fix them at no additional cost. My goal is to deliver a reliable technical asset.
Should I contact you before placing an order?
Yes, please. Every technical project has unique requirements. A brief discussion before starting allows me to analyze your logic needs, database structure, and overall goals. This ensures I can provide the most accurate quote and a technical solution perfectly tailored to your business.
