Denys L. Backend, SQL and API Development

My name is Denys L. and I have over 2 years of experience in the tech industry. I specialize in the following technologies: SQL, Rust, Back-End Development, Docker, API Development, etc.. I hold a degree in Bachelor of Applied Science (BASc), Master of Computer Applications (MCA). Some of the notable projects I've worked on include: Web-based Trading App, Tauri Web Browser, Educational platform, Affine Transformation Estimator, Optimized CSV Data Validation for Financial Analysis Platform, etc.. I am based in Vinnytsya, Ukraine. I've successfully completed 9 projects while developing at Softaims.

I value a collaborative environment where shared knowledge leads to superior outcomes. I actively mentor junior team members, conduct thorough quality reviews, and champion engineering best practices across the team. I believe that the quality of the final product is a direct reflection of the team's cohesion and skill.

My experience at Softaims has refined my ability to effectively communicate complex technical concepts to non-technical stakeholders, ensuring project alignment from the outset. I am a strong believer in transparent processes and iterative delivery.

My main objective is to foster a culture of quality and accountability. I am motivated to contribute my expertise to projects that require not just technical skill, but also strong organizational and leadership abilities to succeed.
