What I'm looking for

I’m looking to own end-to-end delivery—architecture through production—while improving reliability, infrastructure cost, and customer outcomes. I want a team where I can partner with founders and lead technical execution with strong product quality.

I’m a Senior Full-Stack Software Engineer with 6+ years of experience building and scaling software products from concept to production across startups in the United States, Europe, and Asia. I focus on end-to-end delivery—frontend, backend, cloud infrastructure, DevOps, analytics, SEO, QA, and hardware integration.

I’ve launched multiple customer-facing platforms across e-commerce, SaaS, logistics, and IoT, including delivering five production website launches within five months. In these roles, I owned implementation, production releases, SEO, Google Analytics 4 (GA4), and post-launch optimization while partnering closely with product and marketing to improve customer experience and conversion.

I build cloud-native systems on Google Cloud Platform (GCP) and AWS, and I’ve worked on event-driven distributed systems connecting Raspberry Pi hardware to cloud services. I also strengthen reliability and efficiency by improving deployment pipelines, production reliability, infrastructure costs, and engineering productivity through automation.

I’m trusted to make architectural decisions with founders and executives, and I’ve led teams through technical delivery, mentoring, and interviews. From enterprise backend systems and GraphQL services to CI/CD, authentication, and workflow engines, I aim for operational excellence and maintainable engineering practices.
