In the Windsor.ai are developed solutions that allowed companies and ad agencies to connect all of their marketing data, create dashboards, analyze return on ad spend, etc.

Accomplishments:

• Created 4 connectors (Apple Search Ads, Taboola, Mailchimp, and Instagram).
• Created 2 new destinations, Amazon S3 and Azure Blob Storage.
• Contributed to the strict code quality policies that allowed other developers to deliver back-end features/improvements much faster (according to their yearly reflection).

Routine responsibilities:

• Code review.
• Mentored new developers (and team members when it came to tech topics).

Round Competitive is a mobile game that uses Telegram messager to operate (no installment needed). Users team up in groups of up to 10 people each and chase each other in a city. All the "chasers" and "targets" must form only one circle of "chasing dependencies". If you come close enough to your "target" you take his/her points. Every minute you lose N of your points, so you can't just run away. The last player standing wins.

He was the only developer working on this freelance project, so all the features above were implemented by him.

Accomplishments:

• Created an MVP in a short amount of time;
• Designed the whole architecture for the project;
• Added multi-language support using i18n and POEditor;
• Added multi-sessions support.

This was basically a store with crypto payments. It allowed its owner to receive payments in Bitcoin (the currency choice is the client's requirement) from all over the world.

Accomplishments:

• Designed an architecture solution for the whole project;
• Integrated crypto payments in Bitcoin and no payment was lost or we had issues with it;
• Used asyncio to make the bot ready in case of lots of customers (e.g. Black Friday), so the client doesn't lose revenue then.

Failures (would be fair to list):

• Underestimated the time (and the budget) the project would take, because of integrating crypto payments and making sure they work properly.

Stock Flipper is the community of traders who follows market moves (usually day-traders) and try to get profit following them.

​

Accomplishments:

• Designed the proper architecture of the bot;
• Implemented the user interface using a Discord bot;
• Implemented async execution of two event loops: one checking for new incoming messages and the other monitoring price change for the stocks.
