What I'm looking for

I seek senior engineering roles combining hands-on full‑stack development, platform scalability, and technical leadership within collaborative, product-focused teams.

I am a senior software engineer with 18 years of experience designing, building, and scaling high-performance web applications across startups, enterprises, and remote-first global teams. I have deep hands-on experience across frontend and backend stacks, cloud infrastructure, and DevOps.

My work includes modernizing legacy platforms, improving scalability and performance, and delivering production systems using React, Vue, Angular, Node.js, Python, Docker, Kubernetes, AWS and GCP. I have led frontend architecture, backend optimization, CI/CD pipelines, and platform migrations that reduced query times and accelerated product delivery.

I enjoy mentoring engineers and collaborating with product and operations stakeholders to translate complex requirements into reliable, maintainable software. I seek roles where I can balance hands-on engineering with technical leadership to drive long-term system health and measurable business impact.
