    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 &b...

    I’m creating a small, step-by-step temple-preparation game for PC and need a Unity developer who can take it from concept to a playable build. The experience is meant to feel stylized rather than photoreal, so shaders, lighting, and asset choices should lean into that look while still running smoothly on a desktop machine. Core loop The player arrives before dawn and must perform nine temple chores in the correct order—lighting the diya, sweeping leaves, gathering flowers, all the way to ringing the bell when the shrine is ready for sunrise. Each completed action should unlock the next area or object, with soft UI prompts that nudge but don’t hand-hold. When the final bell rings, the sky transitions from night to a warm sunrise, the score tallies, and a short win scene...
