About Me
Architecting the modern web products
I'm a Software Engineer at UCTalent Labs with more than a year of experience contributing to web projects in an environment that builds both products and outsourcing work. During that time, I have worked as a fullstack developer and become familiar with agile workflows.
What keeps me motivated is understanding real user problems and turning them into practical solutions through technology. Long term, I want to build my own company and create products with real impact.
