My professional career has been running on three separate but often closely related tracks: Desktop, Web, and Mobile Application Development. But in the last couple of years, my work has been focused on Mobile Application development and Telegram bots development. I have excellent troubleshooting and debugging skills developed over the years of engineering work in various fields. I am a patient, thorough person with high attention to detail. I can provide consulting, software development, testing/debugging and other services ranging from short one-hour jobs to full-time everyday work, to long-term cooperation and support.
