I help companies design and build scalable backend platforms, enterprise applications, payment systems, and cloud-native services using proven engineering practices combined with modern AI-assisted development workflows.
Over the last 13+ years, I have delivered software solutions across fintech, payments, tax compliance, OTT streaming, IoT, AI, blockchain, and digital marketplaces. My experience ranges from hands-on engineering to architecture leadership and technical management of cross-functional teams.
Most recently, I have been working as part of Upwork's Platform Engineering organization, contributing to Payments and Tax Regulatory Compliance systems that support a global marketplace operating at significant scale.

I actively leverage modern AI engineering tools including Claude and Cursor to improve development velocity, reduce repetitive work, and accelerate delivery cycles.
My approach combines AI-assisted implementation with human architectural oversight, engineering validation, and production-grade quality standards. This approach allows to move faster while maintaining maintainability, security, and long-term scalability.
AI can accelerate code generation. Engineering experience ensures the right systems are built. The combination of both delivers exceptional outcomes.
