Hi! I'm Lucian Olosutean
Building robust backend systems, modern websites, and AI-enabled software products.
About Me
I'm a results-driven Software Engineer with 13 years of experience. My core strength is backend development with technologies like Java, Spring Boot, RabbitMQ, Redis, and PostgreSQL, where I focus on scalability, robustness, and clean architecture. In parallel, I've delivered production websites and full-stack applications for both personal and client projects.
I'm also passionate about the role of Artificial Intelligence in software engineering and product delivery. In daily work I use AI tools such as GitHub Copilot Agent, Cursor, and custom GPTs to speed up development, improve delivery quality, and automate repetitive workflows. I apply this approach in backend systems, website development, and AI-assisted applications such as weddnesday.com, om-law.ro, and lolotech.io, and matka.ro.
I thrive in agile environments and focus on delivering clean, efficient code. My experience also extends to mentoring junior developers and contributing to educational initiatives, where I share my passion for software engineering.
