Need a frontend developer who can join an existing SaaS product, understand a complex codebase, and work independently without constant supervision? I build and take ownership of complex frontend features - from data-heavy dashboards and advanced filtering to authentication, visualizations, and API-driven workflows. I'm comfortable working directly with founders, CTOs, and backend developers, turning business requirements into production-ready features without needing every implementation detail specified for me. Much of my recent work has been on a B2B SaaS platform where the frontend needs to make large amounts of complex data genuinely useful to customers. I've built product areas involving advanced tables, multi-layer filtering, URL-synced state, interactive charts, authentication, infinite scrolling, responsive interfaces, and complex API integrations. I don't just implement a provided design and move on. I regularly work through unclear requirements, identify edge cases, suggest UX improvements, and collaborate with the team to figure out what the feature should actually do. I'm particularly comfortable with: • Complex React & TypeScript applications • Data-heavy dashboards and internal tools • Advanced tables, search, filtering, and pagination • REST API integrations and asynchronous data • Authentication and permission-based interfaces • Charts and data visualization • Responsive UI and reusable component systems • E2E testing and maintaining existing production applications My main stack includes React, TypeScript, JavaScript, Material UI, React Query, REST APIs, Cypress, and Git. I prefer long-term collaborations where I can learn the product and business rather than repeatedly jumping between small one-off tasks. Some of my best work has come from becoming a trusted part of a small development team and gradually taking ownership of larger areas of the product. I currently have room for one additional long-term collaboration of around **10–15 hours per week**. If you have an existing SaaS product that needs reliable frontend ownership, send me a message with a little about the product, your current team, and what you're trying to build or improve.
