Services • Device to interface
WillowSoft helps teams build the full product stack: embedded devices, firmware, connectivity, backend, PostgreSQL, web/admin, mobile and VR layers designed to work together.
Service architecture
Trusted by global teams
Service system
The services are grouped by product layer, so buyers can quickly understand where WillowSoft fits.
Device engineering
For teams building physical IoT products that need reliable sensing, power, RF behavior and production-ready firmware.
Typical output PCB package, firmware source, RF notes and production handoff.
Cloud & data
For products that collect device data, need authentication, reporting, alerts, dashboards and scalable operational data models.
Typical output API contracts, database schema, auth flow and reporting queries.
Operator interface
For teams that need operators, customers and field technicians to actually use the connected product every day.
Typical output Dashboards, mobile flows, user roles, alerts and portal screens.
Immersive
For products or environments that are hard to explain through flat screens, training documents or static presentations.
Typical output Simulation scene, training flow, 3D presentation and demo assets.
Deliverables
The deliverables are practical: source files, firmware, APIs, data models, dashboards and deployment documentation.
Concept to Production
Requirements, field conditions, integrations and technical risks are clarified first.
Hardware, firmware, API, database and interfaces are planned as one system.
The product is developed across layers without vendor hand-off gaps.
RF, device stability, API reliability, UX and field readiness are tested together.
Frequently asked
Engineering buyers usually arrive with the same operational questions. Here are the answers — the rest happens in the discovery call.
WillowSoft delivers end-to-end connected product engineering across eight disciplines: embedded hardware design (custom PCB, RF, low-power), firmware development (STM32, RTOS, OTA), backend APIs (REST + WebSocket, auth, ingestion), PostgreSQL database architecture, web platforms and admin panels, native iOS (Swift) + native Android (Kotlin) + Flutter cross-platform mobile apps, VR & simulation, and IoT cloud telemetry.
Yes. WillowSoft owns every layer of a connected product — hardware, firmware, RF/LoRaWAN connectivity, backend, database, mobile and web interfaces — so customers do not need to coordinate multiple vendors or translate requirements between disconnected teams.
Core stacks include STM32WL Cortex-M4 microcontrollers, LoRaWAN 1.1.0, Modbus RTU, BLE, Wi-Fi, FreeRTOS, REST APIs, WebSocket, PostgreSQL, Swift (native iOS), Kotlin (native Android), Flutter, Three.js / WebGL for web, and Unity for VR simulations.
Yes. WillowSoft's engineering process includes RF tuning, device stability, certification support (CE, FCC, TELEC, KC), production handoff and ongoing field improvements.
Yes. WillowSoft signs mutual NDAs at the start of any commercial conversation involving customer hardware specifications, intellectual property, or sensitive deployment data.
Hardware prototypes typically take 4–8 weeks. Full connected product systems (hardware + firmware + backend + dashboard + mobile) typically take 4–6 months from kickoff to field-ready deployment.
The customer owns the project IP — schematics, firmware source, backend code, mobile apps. WillowSoft retains rights to its internal reference libraries, certified RF blocks and reusable platform components that pre-exist the engagement.
