What I'm looking for

I seek roles where I can lead technical projects, build high-quality Java and TypeScript solutions, collaborate cross-functionally, and drive measurable product improvements.

I am a dynamic Senior Java Developer with over 8 years of experience building robust software and improving client applications. I focus on delivering high-quality solutions that align with IT strategy and customer requirements.

I have engineered and maintained Java client applications, developed responsive TypeScript frontends, and created IVR and virtual assistant components. I collaborate across teams to ensure seamless integration and efficient data flow.

My background includes contributions to deployment tooling and technical support workflows, including ticket-based customer support and installation/configuration tasks. I have also worked on supply-chain optimization, reporting solutions, and C/C++ service integration.

I bring strong technical leadership, a commitment to quality assurance, and a track record of driving successful software initiatives across remote and on-site environments.
