Marina Savelieva

Delivered frontend features for enterprise web applications across financial management, medtech, and logistics. Focused on complex, data-heavy interfaces, accessibility (WCAG), performance optimization, maintainability, and reliable API integration. Worked on payroll and financial management systems with large datasets, filtering/pagination, and form-heavy workflows, and drove a Material UI design system to full component coverage. Implemented responsive, accessible, pixel-perfect layouts for a medtech product used by clinics, students, and universities, and resolved a critical mobile performance issue end to end. Built logistics dashboards for quotes/RFQ and led technical-debt reduction improving stability for corporate clients. Used AI-assisted development tools (Claude Code/ChatGPT/Codex) daily to speed up debugging and development.

Full-cycle development from architecture and design to implementation and deployment for projects including Payroll and Financial Management System, Voka medtech application, and a tool to create and organize documents for delivering goods worldwide. Built interactive UIs with React and a wide range of JS libraries (testing, UI, state management). Also gained experience with backend technologies (PHP, Node.js).

Designed, built, and shipped custom web tools for clients end to end, from gathering requirements to delivery and iteration. Led a lead-generation tool with React UI for browsing/filtering/managing large contact lists and integrated it with a data-collection backend to support email outreach campaigns. Developed an AWS automation internal tool to run and track routine tasks through a simple interface. Built a medical clinic platform organizing patient interactions and supporting software using Java (Spring Boot, Hibernate) and MySQL.
