What I'm looking for

I seek a role building scalable, high-performance web systems where I can own full-stack features, drive architecture improvements, and integrate AI to increase product impact.

I am a Senior Full Stack Engineer with over 8 years of experience building end-to-end web applications, from responsive frontends to scalable backend and database architectures. I specialize in improving system performance, implementing serverless architectures, and integrating AI-driven features to drive business value.

I have a proven record of optimizing page load speed and user engagement, migrating legacy systems to modern architectures, and collaborating across product, design, and QA to deliver reliable enterprise solutions. I prioritize maintainable code, performance audits, and automation to ensure long-term system reliability and operational efficiency.
