Freelancer profile translated to English.

Description

Senior developer specializing in frontend technology for over 7 years. My work goes beyond the visual layer: I develop with a focus on reliability, solid day-to-day operation, and high performance.

I work autonomously, taking full responsibility for my deliverables. I adapt quickly, prioritize with judgment, and advance the backlog without constant supervision. I maintain clear and transparent communication to ensure alignment and pace in the project.

I can join projects in various phases: designing a frontend architecture from scratch, joining an ongoing team, leading or accelerating delivery, taking ownership of a blocked backlog, stabilizing a product in production, optimizing performance, improving DX, elevating code quality, refactoring codebases, migrating technology (e.g., to modern React or TypeScript), etc. Regardless of the project's state or challenge, get in touch with me, and within days, we will generate results.
