What I'm looking for

I seek senior engineering roles building scalable, AI-enhanced backend and full-stack systems in agile teams, with opportunities to lead, mentor, and improve performance, observability, and CI/CD.

I am a Senior Software Engineer with 15 years of experience delivering Java-based full-stack and backend solutions across EdTech, gaming, and InsurTech startups. I specialize in Spring Boot, Spring Security, microservices, and AI/ML integration using TensorFlow, scikit-learn, Deeplearning4j and related tools to drive measurable performance gains.

At Classkick and PlayVS I led engineering efforts that reduced latency by up to 30%, improved engagement and reliability, and increased scalability for thousands of concurrent users. I architect and implement production-ready systems—APIs, event-driven backends, and AI-enhanced services—while mentoring teams and improving CI/CD and observability.

I am dedicated to solving hard technical problems in agile environments, learning new technologies quickly, and delivering scalable, AI-powered software that optimizes performance and drives business impact.
