I deliver fully responsive, cleanly typed code that connects smoothly to your backend — no guesswork, no rework. With 4+ years of experience, I don't just take a design and code it — I understand UX flows well enough to shape what's buildable before development starts, and backend architecture well enough to know exactly how the frontend should connect. I'm the piece that keeps design and engineering aligned, so what ships actually works. 𝑯𝒆𝒓𝒆'𝒔 𝒘𝒉𝒂𝒕 𝑰 𝒄𝒂𝒏 𝒅𝒐 𝒇𝒐𝒓 𝒚𝒐𝒖: 🔹 𝘋𝘦𝘴𝘪𝘨𝘯-𝘵𝘰-𝘊𝘰𝘥𝘦 — I design your SaaS or dashboard interface in Figma, then build it myself, so nothing gets lost in translation between design and development. 🔹 𝘍𝘳𝘰𝘯𝘵𝘦𝘯𝘥 𝘋𝘦𝘷𝘦𝘭𝘰𝘱𝘮𝘦𝘯𝘵 — You already have a design and need it built pixel-perfect, fully responsive, and production-ready. Skilled in Angular, React, TypeScript, and modern component architecture. 🔹 𝘉𝘢𝘤𝘬𝘦𝘯𝘥-𝘈𝘸𝘢𝘳𝘦 𝘋𝘦𝘷𝘦𝘭𝘰𝘱𝘮𝘦𝘯𝘵 — With backend experience in Spring Boot, I understand API design and data structures, which means cleaner integration and better communication with your backend developers.
