About

I am an Engineering Operations (EngOps) Engineer with over 20 years of experience in designing, operating and optimizing mission‑critical data platforms, primarily based on Oracle and increasingly PostgreSQL. In my current role, I work at the intersection of engineering, operations, and architecture, helping teams deliver stable, scalable and efficient systems. My focus is on data platform architecture and the transformation from on‑premise environments to hybrid and cloud‑based solutions (AWS/Azure), ensuring stability, performance, and cost control throughout the transition. I bring a combination of deep operational expertise and architectural thinking, particularly in environments where data platforms are business‑critical and reliability is essential. Core strengths: Data platform architecture (Oracle, PostgreSQL, hybrid cloud) Engineering operations & platform enablement Legacy‑to‑cloud transformation strategies High availability, performance tuning, and stability engineering Data platform governance, risk and cost management I am most effective in roles where experience, system understanding and sound decisions are required to ensure long‑term platform stability. 🔹 Open to remote opportunities (80%) 🔹 Interested in international projects and transformation programs
