I’m expanding the mobile arm of our lead-to-provider matching platform and need a mid-level engineer who can jump in part-time and make an immediate impact. The core app is written in Flutter and Dart, but some legacy and companion modules live in React Native, with the occasional Swift or Kotlin touch-up—so being comfortable switching contexts is essential. You’ll be shaping new features from scratch, refining existing ones, and keeping the overall architecture clean, modular, and ready to scale. Typical work includes full-cycle app development: crafting UI, wiring business logic, integrating APIs, and hardening performance on both iOS and Android. While the initial focus is on our main product, spin-off business, social, and e-commerce–oriented mini-apps a...

I’m looking for a United-States-licensed Professional Engineer or Architect who can take a project from the very first sketch through to a permit-ready package and filing. The work involves three core services—building design, structural analysis, and the production plus submission of permit drawings—and must be completed under your own professional stamp. The pipeline spans residential, commercial, and industrial buildings. Most assignments begin at the conceptual or schematic design stage, progress through detailed design, and culminate in the planning/permit phase, so you should be comfortable switching hats between early creative layouts, rigorous structural calculations, and the nitty-gritty of local code compliance. Typical deliverables include: • Code...
