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 for clients and businesses, including matka.ro and om-law.ro.
For local businesses in Romania I sell a one-page presentation site. The offer is site-uri pentru afaceri locale. Two questions I answer in the guides: cât costă un site de prezentare and am nevoie de un site dacă am Google Business.
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 when building AI products such as weddnesday.com and tavoris.ro, and on this AI-enabled personal platform, lolotech.io.
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.
