Synterra Software

Synterra Software is a founder-led engineering agency specializing in desktop applications for Windows, macOS, and Linux. We combine the capabilities of an experienced development team with the accountability and direct communication of a smaller partner. You won’t be handed off from a salesperson to an anonymous delivery team. You’ll work directly with the engineers building your product, while I remain involved in its architecture, technical direction, and delivery. DESKTOP SOFTWARE IS NOT JUST A WEB APPLICATION IN A WINDOW Production desktop development introduces challenges many web-focused teams underestimate: secure IPC, native operating-system integration, auto-updates, code signing, macOS notarization, file-system access, system tray behavior, deep linking, hardware integration, offline functionality, packaging, and reliable distribution. We have implemented these systems in products used by real customers. We use Electron when ecosystem maturity, integrations, and reliable tooling are the priority. We use Tauri when bundle size, startup performance, memory usage, or Rust-backed functionality matter. We don’t force every project into the same stack. We evaluate your requirements, recommend the appropriate architecture, and explain the trade-offs clearly. WHAT WE DELIVER • Cross-platform Electron and Tauri applications • Architecture modernization and JavaScript-to-TypeScript migrations • Secure main, preload, and renderer boundaries • Auto-update and release pipelines • Windows and macOS code signing and notarization • Native menus, trays, notifications, deep links, and file handlers • Offline-first functionality and local data synchronization • Native modules, hardware access, media processing, and OS integrations • Automated testing, packaging, deployment, and production support • Companion web and mobile applications WHY CLIENTS CHOOSE SYNTERRA • 10 years of software development experience • More than 20 products released to real users • 100% Job Success on Upwork • Top Rated Plus status • Direct access to the engineers doing the work • Honest estimates and consistent progress updates • A capable team without the faceless-agency experience We challenge requirements that create unnecessary cost or technical risk. We’ll tell you when something is simpler than expected –and when it is more complicated than it initially appears. We’re not trying to become the biggest software agency. We’re building the one clients actually trust with their products.
