About Me

I’m a Senior Full-Stack Software Engineer who has been building web and mobile applications professionally since 2019. I started out in frontend development, but over time I took on a broader role. Today, I work on application architecture, backend integrations, data models, and the technical decisions behind a product. I also use AI tools in my daily work to explore ideas, solve technical problems, and build software more efficiently.

Over the years, I’ve worked on products in Web3, gaming, content publishing, and enterprise software. My work has included everything from reusable interface components and mobile applications to CMS integrations, localization, live video, and performance improvements.

I enjoy working closely with product owners, designers, developers, and QA engineers. I like to understand why we are building something before deciding how to build it, and I try to find solutions that make sense for both the people using the product and the team maintaining it.

How I Work

▹I’m comfortable taking ownership of a feature early, shaping the technical approach, building it, and supporting it after release.
▹When a task reaches beyond the frontend, I can work across APIs, backend services, and data models while keeping the whole feature in view.
▹I pay attention to the decisions that affect a product over time: application structure, shared components, performance, and code that other developers can understand and extend.
▹I integrate AI tools into my development workflow to support technical research, architectural decisions, implementation, debugging, and code review.
