What I'm looking for

I seek senior/full-stack roles where I can own architecture through deployment, work on scalable systems, collaborate cross-functionally, and drive measurable performance and reliability improvements.

I am a Senior Software Engineer with over seven years of hands-on experience designing, building, and maintaining production software systems across web and mobile platforms.

I deliver scalable back-end services, clean front-end interfaces, and well-structured APIs, taking ownership from architecture through deployment, debugging, and optimization. My work has improved maintainability, reduced query response times, and increased uptime and stability for multiple products.

I value simplicity, clear logic, and long-term systems built to last; I collaborate closely with product and design teams and leverage modern frameworks, databases, and cloud infrastructure to drive measurable results.
