What I'm looking for

I’m open to senior remote roles where I can lead Java cloud microservices and also build AI/LLM-powered systems (agents + RAG). I want teams that value code quality (TDD/DDD), clean architecture, and fast, reliable delivery.

I’m a Lead Software Engineer with 8 years of experience building Java Spring Boot microservices and event-driven architectures on cloud infrastructure. I have a strong track record of migrating legacy systems to modern architectures and shipping to production with zero critical incidents.

At PayxPert, I built a CI/CD pipeline from scratch and delivered push-to-deploy in under 2 minutes, replacing 100% of manual deployments and making the release cycle ~60% faster. I led the migration of a legacy payment platform to microservices, delivering REST APIs for internal teams and real client usage without critical incidents.

I also co-founded a tech startup and actively work with Generative AI and LLM tools—building agent workflows, RAG pipelines, and developer tools. I care about code quality through TDD and DDD, and I bring strong engineering leadership through mentoring, architecture decisions, and pragmatic delivery in Agile teams.
