What I'm looking for

I’m looking for a team where I can build scalable product features end-to-end—front end to APIs—while owning performance, integrations, and CI/CD automation in a collaborative, agile environment.

I’m a Full Stack Software Engineer with over 8 years of experience developing scalable Web and Mobile applications. I focus on delivering high-performance, sustainable solutions by combining strong front-end expertise with back-end REST API development.

On the front end, I work with Vue.js, React, and TypeScript to build and optimize Single Page Applications, improve performance and conversion, and create reusable, component-driven features. I also bring a hands-on approach to integration and user experience, including SEO best practices.

On the back end, I develop with Node.js to design REST APIs and GraphQL resolvers that unify data from multiple sources while reducing over-fetching. I implement secure authentication using JWT and role-based access control, and I work with SQL databases such as PostgreSQL and MySQL.

I’m also strong in scalable system architecture and delivery automation—using CI/CD, Docker, and Git workflows to standardize environments and automate builds, tests, and deployments. I’ve built real-time integrations and middleware (e.g., Pipedrive sync) and have experience with cloud and virtualization tooling for reliable, parallel execution.
