Frequently Asked Questions

Clear answers about building customized web applications with Tech Sreni.

What is the difference between a website and a web application?

A website is primarily informational—presenting services, case studies, and brand content. A web application is an interactive software system with user accounts, database operations, custom business logic, dashboards, and automated workflows.

Where is the web application hosted?

We can deploy to your preferred cloud provider (AWS, Google Cloud, DigitalOcean, or Vercel). We provide automated deployment scripts and full documentation so your team retains complete ownership of your infrastructure.

Can you migrate our existing spreadsheet or legacy database?

Yes. We write automated data sanitization and ETL migration scripts to transfer your historical records (Excel, Google Sheets, Access, old SQL databases) cleanly into the new system without losing data integrity.

What about security and GDPR / data privacy compliance?

We implement industry-standard best practices: data encryption in transit (HTTPS/TLS) and at rest (AES-256), salted password hashing (bcrypt), parameterized SQL queries to prevent SQL injections, and strict CORS and CSP headers.
