As a self-taught software engineer, I am passionate about creating scalable and performatic applications and have a keen interest in reverse engineering. I have experience working with a variety of programming languages, including C#, Kotlin, GoLang, Lua, C++, Python and others. I am also proficient in database management using MySQL and NoSQL, and have experience with containerization using Docker. As a backend developer, I am responsible for developing and maintaining robust backend services. I have experience using NewRelic and Datadog to monitor and troubleshoot applications, and have worked with message brokers like RabbitMq and Kafka to implement messaging patterns in microservices architectures. - Developed a library to automatically deserialize and parse fixed length files into data structures, which has streamlined the team's workflow and increased productivity. - Developed Kong plugins in Lua to verify requests authenticity, as well as log incoming requests. - Worked on data analysis using PySpark, Databricks and SQL to better understand and design a more accurate user score based on internal data. - Developed a highly performatic mass requests client using GoLang with goroutines and channels In my free time, I maintain and develop HunterPie, a widely used Monster Hunter tool with over 30k monthly active users in the community. My dedication to software engineering and my contributions to the community showcase my passion and expertise in the field.
