Who I Work Best With

I take on a limited number of projects at a time β€” so I can give each one my full attention. That's why I'm selective.

βœ… Great fit if you…

  • βœ“ Have a clear app idea you're ready to execute
  • βœ“ Value direct communication and honest feedback
  • βœ“ Care about quality long-term, not just the lowest quote
  • βœ“ Respect timelines and expect the same from your developer
  • βœ“ Startup, SMB, or entrepreneur with a real budget

❌ Not the right match if…

  • βœ— You're looking for the cheapest developer available
  • βœ— You haven't defined what you want to build yet
  • βœ— You need a 10-person agency team assigned to your project
  • βœ— Your app needs to go live in under 2 weeks

Frequently Asked Questions

What mobile app development services do you offer?

Full-cycle mobile development: Flutter iOS/Android app, backend API, UI/UX design, App Store & Google Play publication, and post-launch maintenance. I can handle the full project or just the parts you need help with.

How do you handle projects from different time zones?

I work with clients from the US, UK, Europe, and LATAM regularly. I adjust my schedule to accommodate overlapping hours and use async communication (Slack, Notion, Loom videos) so nothing gets blocked.

Can you take over an existing app project?

Yes. I've taken over several legacy projects. I start with a code review, provide an honest assessment, and propose a realistic plan. No "blank slate only" policy.

Do you provide the source code?

100%. You own all code, assets, and accounts. At project completion I deliver a clean repository with documentation, and you're free to take it anywhere.

How do we start working together?

Send me your idea by email or Upwork message. I'll respond within 24 hours with questions to clarify scope. Then I prepare a written proposal with timeline and budget β€” no commitment required.
