I’m looking for a long-term, full-time coding partner who can move quickly with our agency’s fast-paced workload. Most of what you’ll touch is frontend-heavy, yet you must be comfortable working the full stack when an API tweak or server-side fix is needed. The current stack centers on React for web interfaces and Flutter for truly cross-platform builds. Using Flutter, you’ll ship the same codebase to mobile, web, and desktop, then polish the browser experience further in React when a richer SPA is called for. You’ll collaborate with our designers and project managers, push clean, well-reviewed code, and keep an eye on performance and responsiveness across devices. Typical deliverables include: • Responsive React components that match design specs • A single Flutter codebase compiled to mobile, web, and desktop builds • Minor backend or integration updates when required for feature parity If you are reading this properly send me a message that starts with "lets do this". send an email to hello+hire@digitalsauce.i(o) I value clear daily communication, rapid iteration, and reliably hitting agreed timelines. If you love React, live and breathe Flutter, and don’t mind jumping into the backend now and then, let’s talk. This is a full time commitment, budget will be allocated as per the experience level. We want someone drive, who has experience making apps and understanding working with AI and knows how to remove its slop when needed.

Hi, lets do this This kind of role works best when there’s someone who can move fast without breaking consistency across projects. The real goal is not just shipping features, but keeping React and Flutter outputs aligned so the user experience feels cohesive across web, mobile, and desktop. The main failure point in setups like this is context switching. Without a clear approach, Flutter handles shared logic one way while React evolves separately, and small backend tweaks start introducing inconsistencies. I’d approach this by keeping a clean separation of concerns, reusing patterns where possible, and making sure every feature shipped is stable enough to build on, not just quick to deliver. I’m comfortable working across React, Flutter, and backend touchpoints, and I’m used to fast iteration with clear daily communication. I’d start by aligning on your current workflow, priorities, and code standards so I can integrate smoothly from day one.
