Frequently Asked Questions
What types of projects do you take on?
I work on SaaS products, MVPs, custom web applications, API integrations, internal tools, performance improvements, and ongoing maintenance for existing platforms.
How long does a typical project take?
Small fixes and focused features can take a few days, while full MVPs or SaaS builds usually take several weeks depending on scope, integrations, and feedback cycles.
Do you provide ongoing support after launch?
Yes. I can provide launch support, bug fixes, performance monitoring, feature iterations, and retainer-based maintenance after the initial delivery.
What is your payment structure?
Projects can be billed hourly, as fixed-scope milestones, or as a monthly retainer. The right structure depends on how defined the scope is and how much ongoing support you need.
Do you work with international clients?
Yes. I work remotely with clients worldwide and keep communication clear through async updates, scheduled calls, and shared project tracking.
Can you work with my existing codebase?
Yes. I can review your current codebase, identify risks, improve architecture, fix bugs, add features, and document the changes so your team can keep moving.
No hard sell
What is slowing your product down?
