What I'm looking for

I am seeking senior engineering roles where I can architect scalable systems, lead cross-functional teams, mentor engineers, and deliver measurable product and revenue impact.

I am a Senior Full Stack Software Engineer with 12+ years of experience building scalable, high-performance applications and external integrations using Python, Golang, React, and Node.js. I architect end-to-end solutions for API integrations and eCommerce-like platforms, deliver production observability, and mentor engineers to establish best practices across organizations.

My work has driven product revenue and user experience through multi-tier routing frameworks, real-time analytics dashboards, and secure third-party integrations. I collaborate closely with cross-functional teams, lead architecture reviews, and focus on operational reliability, testing, and measurable outcomes.
