SUMMARY
Enthusiastic and detail-oriented Java Developer with over a year of commercial experience, proficient
in both Java and Kotlin languages. Passionate about creating cutting-edge solutions, I have worked as
a key contributor in the development of an online help assistant utilizing Google&# 039;s Speech-to-Text and
Text-to-Speech services, server deployment on AWS, and the implementation of the Retrieval
Augmented Generation Postgres PGVector database. My individual contributions include the fine-
tuning of the ChatGPT model and the development of a parsing module via HtmlUnit Java library for
resource extraction. Alongside my solid technical skills, an innate ability to adapt and learn, and a zest
for innovation, I strive to contribute effectively to dynamic teamwork for the achievement of project
goals while pushing the boundaries of technology.
