Architected and built a Next.js application for a recruitment platform — SSR and Server Actions, full-stack feature delivery (UI + REST integration), and AI-powered document-to-profile flows alongside search and recruiter-facing tooling. Integrated generative AI / LLM APIs for CV intake: structured extraction, smart profile prefills, and guardrails on edited content before publish. Delivered multi-step forms (Zod, React Query, Zustand), comprehensive localization across the application, and dynamic PDF output for candidate summaries. Established a robust CI/CD pipeline utilizing Docker and GitHub Actions, accelerating deployment cycles by 34% and ensuring consistent and reliable releases.
