Technical specifications for the Telegram bot
The work was completed on time, satisfied with the result, as everything that needed to be done was accomplished.
A competitor analysis was conducted, based on which the functionality was refined.
As a result of drafting the technical specifications, the number of repeated functionalities was reduced by integrating some functions into other menus.
A detailed description of the functionality was created, taking into account all nuances of Telegram's restrictions and limits.
A phased work plan was developed, dividing the functionality into modules, which makes it convenient to add features when creating the bot.
Technical requirements were written, including deadlines and definitions, making it clear who is responsible for which functionality.
As a result, a technical specification was developed, with which I can now find a contractor who will assess the exact cost based on my specifications and clearly understand what needs to be done.

I didn’t expect such a calmness of adequacy from Alexandra. I am the nervous customer who doesn’t understand either in the codes or in the TZ – but Sasha forgived me and gave me the opportunity to clarify everything on his break. Generally ordered a bot - all clearly fast and with detailed explanations as for a blonde. I am very happy and I recommend it to everyone!

Cryptocurrency Binance Data Processing Program with Signal on Telegram
Alexander fulfilled his task at 199%, initially the task was to upload the data to the Google Table, which he did and showed clearly that from the big volume of information the table hangs and proposed the option of the solution to do everything in the code. It makes it easy to work with the data. Pleasantly surprised the level of involvement in the project, Alexander constantly corrected and fixed the faults that we didn’t talk about at first. He didn’t place in a long box (he often encountered freelancers who feed “morning”, that’s sick). I will definitely address in the future!
