What I'm looking for

I’m looking to architect and scale ecommerce platforms where I can lead full-stack delivery, improve reliability and performance, and drive measurable conversion gains through A/B testing and marketing integrations—collaborating closely with product and marketing teams.

I’m a Senior Software Engineer with 10+ years of experience architecting and scaling high-traffic ecommerce platforms. I’ve led full-stack development initiatives that improved site reliability, customer conversion, and digital marketing integration for thousands of retail clients.

At Kyndryl, I architected a multi-tenant ecommerce platform serving 500+ retail clients, delivered microservices with 35% faster API responses, and supported 2M+ daily requests with 99.9% uptime. I migrated a legacy monolith to distributed architecture on AWS, cutting infrastructure costs by 30% and improving deployment frequency 5x.

I’m equally focused on performance and experimentation—building a React/TypeScript storefront, integrating third-party marketing tools into a unified dashboard, and enabling A/B testing and personalized recommendations. I also drive engineering excellence through CI/CD automation, load testing, and mentoring junior engineers to accelerate team velocity.
