Frequently Asked Questions
Here are answers to common questions about timelines, technologies, and working with me.
What technologies and frameworks do you specialize in?
I build applications with ASP.NET (MVC/Core), C#, JavaScript/TypeScript, Angular, React, React Native, and integrate databases like SQL Server & MySQL.
How long does a typical website or app project take?
Small brochure-style sites often take 1–2 weeks; medium web apps or portals run 4–6 weeks; larger enterprise projects vary from 2–4 months depending on scope.
Do you offer ongoing maintenance and support?
Yes—monthly support packages include updates, security patches, backups, and minor feature improvements to keep your site running smoothly.
Can you integrate payment gateways like PayPal and Stripe?
Absolutely—I’ve integrated both PayPal and Stripe for one-time and subscription payments, ensuring PCI compliance and a seamless user experience.
How do revisions and feedback work during development?
I use an Agile approach: we define requirements, iterate in sprints, and you get to review builds frequently. Typically 2–3 rounds of revisions are built into the scope.
Can you set up marketing campaigns and SMS triggers?
Yes—I integrate Facebook Ads campaigns, SMS notifications, and email workflows via Twilio or SendGrid to automate marketing and user alerts.
