About

I’m a results-driven engineering leader with 9+ years of experience turning complex requirements into production-ready platforms in highly regulated, customer-facing environments. I thrive in challenging scenarios and wear many hats—from technical consultant and architect to stakeholder partner and mentor. What I love to do: 🚀 Drive end-to-end integrations: Partner with product, engineering, operations, and biz-dev to gather requirements, define features, and roll out at scale. ⚙️ Architect resilient microservices: Build cloud-native, Kafka-powered pipelines with Java/Spring Boot, SQL/MySQL, Linux, Kubernetes, and AWS/GCP. 🤝 Manage stakeholders: Translate business goals into clear technical roadmaps, align distributed teams, and deliver under tight timelines. 🌱 Mentor & grow teams: Foster Agile collaboration, continuous improvement, and a culture of developer happiness.
