ABOUT

“Stay hungry! Stay foolish!” – Steve Jobs

I am a Software Engineer with over 20 years of experience designing, building and delivering complex enterprise systems across Java-based backends and modern JavaScript frontends. My expertise includes cloud-native and distributed architectures, modernizing monolithic applications into microservices and, more recently, integrating AI-assisted development tools to enhance engineering workflows.

Since 2020, I have worked independently on international projects in various industries, taking end-to-end ownership of the full software lifecycle — from requirements through design, implementation, testing and deployment. As a full-stack engineer, I ship complete features to production while ensuring alignment with business and technical stakeholders.

For me, building effective software means understanding the business context, keeping the big picture in mind, selecting the right technology stack and thinking outside the box when solving problems. I focus on creating well-engineered solutions that work and make a real difference.
