Frequently Asked Question
If your question isn't addressed here, feel free to reach out—I'm always ready to provide further assistance
If we extend you an offer, how soon can you start working with us?
I honor a two-week notice period to respect my current employer, ensuring a smooth and professional transition. However, if the role is urgent, I’m flexible — I’m willing to dedicate extra hours outside my current working schedule to support immediate project needs or deadlines before officially joining.
Do you have multiplatform development experience with Kotlin Multiplatform (KMM)?
Yes! I have hands-on experience delivering several projects using Kotlin Multiplatform Mobile (KMM), sharing core business logic across Android and iOS. This approach has helped reduce duplicate development efforts, speed up delivery timelines, and ensure consistent feature behavior across platforms.
Do you offer maintenance or support after you leave a project?
Absolutely. I prioritize long-term project sustainability by preparing detailed handovers and, when possible, mentoring junior developers to ensure they can confidently provide ongoing support after my departure. I’m committed to leaving teams set up for success, even beyond my direct involvement.
Do you work with Russian-speaking teams (and do you know Russian)?
Yes, I’ve worked with Russian-speaking teams many times and can comfortably understand and respond to work-related questions in Russian. That said, my preferred working languages are English or Uzbek whenever possible for smoother communication. I’m flexible and experienced in adapting to multilingual environments.
Do you prefer remote, hybrid, or onsite work?
I’m open to all work arrangements, with some flexibility based on location. For onsite roles, I’m available in Tashkent, Fergana, and Andijan. For hybrid positions, I’m open to opportunities anywhere within Uzbekistan. For remote roles, I’m fully open to collaborating with teams from any location globally.
