What I'm looking for

I'm looking for senior engineering or technical leadership roles where I can build scalable, secure AI/Web3 platforms, lead teams, and drive product strategy in a growth-focused, engineering-first company.

I'm a Full-Stack Engineer and DevOps specialist with 13+ years of coding experience, evolving from PHP and WordPress to modern Web2, Web3, and AI ecosystems. I build secure, scalable platforms and lead engineering teams across startups and enterprise banking.

I've architected microservices and enterprise-grade systems using Node.js, NestJS, Java (Spring Boot), Kotlin, PostgreSQL, Docker, and Kubernetes, and implemented CI/CD pipelines that improved deployment speed by 40% and test coverage above 90%.

I lead product- and engineering-focused teams to deliver performant, user-centered solutions—founding and leading a technology company and shipping projects such as ScalOps, Synto, Paylume, and multiple blockchain and AI platforms.
