Curriculum Vitae (CV)

Python Backend Software Engineer
@HotCode

While working on the CRM for internal use in the company, I implemented the LLM so that users using natural language could manage various processes in the CRM. As a result, this increased employee engagement in working with SRM by 50% and also reduced time spent on routine tasks

Python Backend Software Engineer
@ASICS DIGITAL

I communicated closely with the project stakeholders to collect requirements, designed a data collection and storage system, and quickly developed this system for parsing data for many coins, storing it in Mongo and bringing it to production. This allowed the stakeholders to attract investment.

Python Backend Software Engineer, DevOps
@Fabiosa Media

Data Platform for Insights for Fabiosa Media - the top #4 Facebook media publisher in the world:

I created a platform where businesses can find insights into their data and build dashboards and recommendations from Gen AI. It helps to decrease the time for making decisions.

Python Software Engineer
@HEALTH UNION

A network of sites for health care:

While working at the company, I actively created internal frameworks for integration with Apache Airflow, monitoring data quality and testing analysts' SQL scripts. By using pytest during the development process, I ensured our code's high stability and reliability while speeding up the verification and bug-fixing processes.
I developed a service that interacts with networking sites where users express opinions on health topics. The main task of the service was to search for spam among comments and generate content recommendations for the user. To implement this task, I used FastAPI and models created by our data scientists. To increase the efficiency and speed of the system, I actively applied optimisation algorithms and integrated the numpy library into the data processing process.

Python Developer
@Analitycs Dashboards

As part of my project, I collected data from many different sources. Using Python combined with AWS Lambda Functions, I automated the process of retrieving information from the API and storing the data in AWS S3. After the aggregation phase, I initiated ETL processes using AWS Glue to process and structure the resulting information. Then, using AWS Athena, I created a data mart, based on which analytical dashboards were built in AWS Quicksight. These dashboards have become a valuable tool for management, providing deep analytical insight into the data collected.
