🏆 Contributor in big crypto & financial & health care & AI projects and an active participant in non-commercial volunteer projects.
⭐️ Proactive and responsible team player, never afraid to seem inexperienced or admit my own mistakes. Values learning abilities over knowledge, transparency over assumptions, and awareness over ignorance.
🤖 Worked in the backend development of complex CRM systems, applying my in-depth knowledge of databases to optimize processes related to data storage, retrieval, and manipulation. My experience spans various database management systems (DBMS) including MySQL, PostgreSQL, and MongoDB. This has enabled me to design, implement, and maintain efficient, secure database solutions specifically tailored to meet the needs of CRM applications.
