Frequently AskedQuestions

What exactly do you build?
Web applications - from landing pages to full SaaS products. I handle the entire stack: UI design, frontend (React, Next.js), backend (Node.js), APIs, databases, and deployment. One developer, full context, no handoff gaps.
What's your core tech stack?
React, Next.js, TypeScript, Node.js, and PostgreSQL. I also work with Tailwind CSS, Prisma/Drizzle, Docker, and Python. I pick the right tool for the job - not the trendiest one.
What's a realistic timeline?
A landing page ships in 1-2 weeks. A full web application takes 4-12 weeks depending on scope. I provide a detailed timeline upfront and deliver in iterations, so you're never in the dark.
How do you handle communication across time zones?
Async-first. I send clear progress updates, use shared project boards, and make myself available for calls when needed. I've worked with international clients throughout my career - timezone differences don't slow things down.
Do you support projects after launch?
Yes. I offer maintenance packages covering bug fixes, performance monitoring, security updates, and new features. Most of my clients stay long-term because I treat their product like my own.
