(1 review)
We build SaaS, mobile, and IoT software.
HighAppler is a software development studio based in Shumen, Bulgaria, working primarily with companies in the United States and Western Europe. We're deliberately a small team: six senior engineers who have worked together for years. No layers, no rotating juniors, no handoffs between sales and delivery. The person scoping your project is the person you'll talk to every week once it's live. What we build SaaS platforms: backend architecture, APIs, multi-tenant systems, integrations Web applications: typically Java on the backend, modern JS frameworks on the front Mobile apps: native and cross-platform, often paired with a SaaS backend we also build IoT software: including embedded device communication, telemetry, and dashboards QA and test automation: as a standalone offering or wrapped into the build Where we go deepest Java and backend engineering is our home turf. We've spent more than seven years embedded with a US construction SaaS company, building and maintaining the platform their customers rely on every day. We've also delivered IoT software for the Nikola Kozlevo project, where our code runs on physical hardware in the field. How we work Long-term partnerships, not flings. Async-friendly, US-time-zone-friendly, and direct in our communication. If something's a bad idea, we'll say so before you've paid for it. Tell us what you're building and we'll tell you honestly whether we're the right team for it.
