What I'm looking for

I seek roles where I can lead full-stack development, design APIs, implement CI/CD and cloud solutions, mentor teams, and deliver measurable performance and reliability improvements.

I am a Senior Full-Stack Engineer with deep experience building scalable, high-performance applications using Node.js, Java, C#, modern JavaScript frameworks, and cloud technologies. I have a strong track record in API design, CI/CD automation, containerization, and improving system reliability while mentoring junior engineers.

I deliver measurable results—improving performance, reducing bugs, and accelerating deployments—by implementing automated pipelines, robust testing, and observability tooling. I collaborate closely with product and customer teams to translate requirements into impactful features that increase adoption and drive operational efficiency.
