I am highly experienced in working with corporate network configuration and infrastructure deployment, which underscores the importance of reliable and efficient networking in modern technology landscapes. Additionally, I possess a strong proficiency in low-level programming languages, particularly in C, which complements my broader skill set.
I have significant experience with Python, but my recent interests and the changing demands of the industry have led me to focus more on Golang. Although I have worked with PHP, specifically Laravel 7.2, in web development, my primary focus remains on networking and Golang.
Throughout my career, I have consistently demonstrated the ability to lead and execute complex projects in VoIP and cloud service environments. I am committed to driving technological advancements in telecommunications. This has been a defining aspect of my professional development, positioning me as a forward-thinking and versatile contributor in the ever-evolving world of technology.
Additionally, I refactored the code, fixing billing inaccuracies and resolving financial discrepancies. These changes have significantly improved our operational efficiency. I have consistently advocated for the automation of business processes to increase productivity and streamline operations.
In my previous roles, I have successfully managed projects with a strong emphasis on providing excellent service. Furthermore, I have a proven track record of creating automation tools using Python, specifically FastAPI. These tools include bot development, payment systems, and robust authentication mechanisms. My career demonstrates my unwavering commitment to enhancing systems administration and DevOps through innovative and efficient practices. I am confident in my ability to deliver results and exceed expectations.

Ukraine · 1 year of experience · Upper-Intermediate ·Published 10 March
As a GO developer, I created an Ethereum-based service providing donation-collecting functionality similar to "banka" from monobank. Users can create a new donations account, generate a new Eth wallet, get transactions, withdraw donations to their personal accounts, and get recommended GAS prices based on the GAS of the latest blocks.
- Developed a database storing jar id, status and data using SQLite Rised an Ethereum node on infura.
- Created several log levels using logrus module.
- Created a module that creates a jar and generates new Ethereum wallet and assigns it. To generate a new wallet eth_client was used.
- A module that checks the balance used in transactions and jar/wallet donations history.
- A new transaction module was developed that handles transactions: It takes a private key, generates a public key, and wallet address, and transfers donations to the
jar wallet.
- In order to recommend GAS price last blocks were analyzed using Etherscan API.
- The application was built using RESTful API written on GIN and run on AZURE.
