What I'm looking for

I'm looking to lead and build high-quality AI-enabled SaaS, backend, and microservices products while mentoring engineers, aligning with stakeholders, and improving delivery speed through strong technical standards.

At Designli, I lead multiple software projects, aligning developers, Product Owners, QA engineers, and stakeholders around system design, AWS, DevOps, code reviews, and technical documentation. I also promote agentic engineering practices that have helped teams deliver features and modules in a month or less.

I've architected and maintained backend infrastructure for a golf platform serving thousands of users and more than 50 golf courses, with tee-time integrations growing beyond 200. I translate product requirements into technical tasks and proof of concepts, define MVP scope and viability for new clients, and work directly with clients on implementation plans.

Previously, I built microservices and full-stack platforms at Stefanini, MQA Americas, and 369labs, supporting education, finance, retail, and enterprise security products. I bring hands-on experience across Node.js, Java, Spring Boot, React, AWS, SQL, NoSQL, and AI agent workflows, alongside mentoring, coaching, and technical hiring.
