We're building the new web version of our product and are looking for an experienced front end developer to lead and support the rollout. You'll work primarily in React and [login to view URL], building the interfaces our customers use every day. The frontend integrates with a SQL Server database via a C# API — you won't be modifying the API or database directly, but you'll need to understand relational data and work comfortably against existing APIs. WHAT YOU'LL DO - Build and maintain UI features in React / [login to view URL] - Consume and integrate with an existing C# REST API - Translate designs and requirements into performant, accessible, responsive interfaces - Write clean, maintainable, well-tested code and participate in code review - Collaborate with the wider team (and any backend/API developers) to flag issues, edge cases, or data needs WHAT WE'RE LOOKING FOR - 3-5+ years of professional front end development experience - Strong hands-on experience with React and [login to view URL] (App Router / SSR / routing / data fetching patterns) - Solid JavaScript fundamentals; TypeScript experience strongly preferred - Strong HTML5 and modern CSS skills - Comfortable working with relational databases conceptually (you won't write SQL day-to-day, but should understand schemas, joins, and how data is structured) - Experience consuming REST APIs built by another team (ideally including .NET/C# APIs, but not essential) - Good communication skills — able to work async/remote and flag blockers early NICE TO HAVE - Experience with a component library / design system - Automated testing experience (Jest, React Testing Library, Playwright/Cypress) - Familiarity with CI/CD and Git-based workflows - Experience in construction, CRM, or B2B SaaS products LOGISTICS - Fully remote HOW TO APPLY When you apply, lead with relevant experience; tell me how you've shipped React or [login to view URL] apps that tracked complex regional data and how you kept performance sharp. Links to repos or live products speak louder than a polished proposal.

With my 3-5+ years of professional experience, I have specialized in front-end development, focusing on React and Next.js. This proficiency extends to App Router, SSR, routing, and data fetching patterns. Handling complex relational data fittingly is familiar territory for me. Although my daily tasks won't require SQL queries, I possess a solid understanding of the schema, join techniques, and structuring data. Working against existing APIs is not new to me - I've gained experience consuming REST APIs built by different teams. While .NET/C# APIs knowledge is not necessary for this job, you can be assured of a seamless interaction with the API as I have navigated different backend troughs before. To deliver interfaces quickly and efficiently . Along with this comes my automation testing expertise with Jest, React Testing Library, and Playwright/Cypress that ensures robustness in your codebase. Technique aside, my approach to project mirrors with yours; building clean, maintainable codes for long-term use while providing consistent updates and dependable support throughout the project. In conclusion, hiring me would mean gaining an experienced developer who values similar attributes like clarity in communication, efficient coordination, reliability post-development coupled with strong technical abilities to deliver a first-rate product that matches your real project goals.
