Rivac LabsFrontend Developer
Your product's frontend is the only part of the engineering effort a customer ever actually touches, so it has to load fast, hold up under real device and network conditions, and feel like one coherent piece of software rather than a pile of components. We build interfaces in React, Vue, or Angular that match the design spec exactly, ship clean semantic markup, and hit strong Core Web Vitals scores instead of just looking good in a demo. This matters most when a client has a design that keeps arriving late or slightly broken from build, when conversion is being lost to slow or janky pages, or when a growing app's component layer has become inconsistent across screens. We work directly from your design files and existing codebase, not from a rebuild fantasy.
How We’d Approach This
A clear, staged plan — not a black box
- 1
Audit the current UI, component library, and Core Web Vitals against the design spec and real traffic conditions.
- 2
Stand up or extend the component system on a low-risk screen to prove the patterns before touching the whole app.
- 3
Walk the working screen through design and stakeholder review, adjusting spacing, states, and interactions on real feedback.
- 4
Roll the approved patterns out across remaining screens with performance budgets and visual regression checks in place.
