Досвід роботи

.NET Backend Developer / Tech Lead

з 08.2020 по нині (5 років 8 місяців)
GeeksForLess Inc., Миколаїв (IT)

I work on a large enterprise .NET platform that helps clients understand customer sentiment at scale and make informed business decisions. My role includes maintaining and extending the platform with new features, improving stability, refactoring legacy modules, and ensuring consistent, reliable data processing.

I also took on technical leadership responsibilities within the project: guiding architecture discussions, mentoring a team of 6 developers, reviewing code, and supporting the team in delivering high-quality solutions.

Key achievements include significantly improving performance and reliability across several core systems. I optimized critical workflows, boosting their speed by 2-10x, rewrote the legacy reporting engine and reduced generation time by over 97%, implemented a high-performance Excel export handling (1M rows with formatting in ~1 minute), and built a management module for handling customer feedback. These improvements helped increase platform stability, speed, and overall usability for enterprise clients.

Додаткова інформація

I am a .NET Backend Developer with almost 6 years of experience building and improving enterprise systems. I focus on clean architecture, stable performance, and simple, reliable solutions to complex technical problems.

On my current project, I took on technical and leadership responsibilities: I coordinate a team up to 6 developers, support a large .NET platform, and mentor colleagues through code reviews and architectural guidance.

I worked with ASP.NET Core, Web APIs, MS SQL Server, EF Core, and Dapper. I enjoy improving performance, refactoring legacy code, and building features that solve real business needs.

Some of my key contributions include rewriting the reporting system (97% faster), implementing high-performance Excel export (1M rows with formatting in ~1 minute), and creating a secure Auth API with JWT and key rotation.

Built a WPF desktop application used by hundreds of users, featuring data binding, async/multithreading, and
TCP communication.

I’m always open to feedback, and motivated to grow as a developer and team contributor.
