Parser

Personal 157 USD

I categorically do NOT recommend collaborating with this contractor! After payment, according to his words, he started working, but before the project deadline, he wrote that he had force majeure circumstances and asked to postpone for another day, to which I agreed with understanding - after which he completely stopped reading and responding to messages (despite being online and accepting other projects). Do not waste your time on him in vain, as I see from other reviews this is a standard situation for him. The deadlines set by him were 2 days, after which for almost another week I did not close the project and tried to get at least some response from him about whether the project would be completed, but I never received anything. Terrible!

Redesign of the Telegram bot from scratch under the existing token (CRM + subscriptions)

Personal 404 USD

Unfortunately, the project was not completed. The performer delayed the deadlines, postponing the submission of the project each time. As a result, he stopped responding. I noticed that Viktor has 4 projects simultaneously in progress. Perhaps, he miscalculated his own abilities.

Retest of the Telegram bot, for which testing was conducted.

Personal 50 USD

Viktor performed the testing and retesting of the project with high quality. The check was conducted carefully and thoughtfully: scenarios were reproduced sequentially, edge cases were recorded correctly, and reports were structured and accompanied by videos and screenshots.

I would like to note the professional approach — Viktor asked clarifying questions on controversial points and focused on the actual behavior of the product, rather than on a formal search for bugs. As a result of the work, no critical regressions were identified.

I can recommend Viktor as a responsible and attentive QA specialist.

Testing of the Telegram bot. Complete functional and negative testing (according to the prepared technical specification)

150 USD

Viktor completed a full cycle of functional and negative testing for my Telegram bot.

I was more than satisfied with the work.

Viktor approached the task in a highly professional manner:
- he carefully studied the technical specifications, clarified important points, and offered valuable suggestions;
- he built a clear structure of test cases and fully covered all scenarios, including complex FSM branches;
- he checked positive, negative, contextual, and non-standard scenarios, as well as all types of inputs and edge cases;
- he prepared a very detailed and neat report with descriptions of steps, expected/actual results, screenshots, and a clear classification of found bugs.

As a result, I received a truly professional test report at the Senior QA level, which became a solid foundation for further product development. It is clear that this person has a deep understanding of both testing and the logic of how Telegram bots work.

I would like to specifically highlight his accuracy, speed, transparency in communication, and respectful attitude towards the task.

I recommend Viktor to anyone in need of a quality, attentive, and technically proficient QA specialist. I will definitely reach out again.
