What makes IoT development different from standard software development?
IoT development combines embedded programming (hardware-specific, resource-constrained), wireless connectivity protocols, cloud services, and user interfaces into a single ecosystem. It requires expertise across multiple domains: from low-level C/C++ firmware and wireless protocols like BLE or LoRaWAN to cloud platforms and mobile app development. IoT embedded systems must operate reliably in diverse environments. Our team brings this cross-domain expertise under one roof as a complete IoT software development company.
How long does it take to develop an IoT solution?
Development timeline depends on project complexity. A basic proof-of-concept can be ready in 4-8 weeks. Full-featured systems typically require 3-6 months from concept to production. We follow an agile approach with regular deliverables, allowing you to see progress throughout development and iterate based on feedback.
How do you ensure IoT security?
We implement security at every layer: secure boot on devices, encrypted communication channels, certificate-based authentication, and regular security updates. Our solutions follow security best practices like the OWASP IoT Top 10 and industry-specific standards. We conduct security testing throughout development to identify and address vulnerabilities.
Can you integrate with existing systems and equipment?
Yes, we specialize in connecting legacy systems to modern IoT platforms. We develop custom connectors and gateways that bridge proprietary protocols with standard IoT communication methods. Our solutions can integrate with ERP systems, databases, and third-party services through RESTful APIs, webhooks, or custom interfaces.
What IoT communication technologies do you work with?
We have extensive experience with Bluetooth Low Energy (BLE), WiFi IoT, LoRaWAN, NB-IoT, LTE-M, MQTT, and HTTP/REST. Our team selects the appropriate technology based on your specific requirements for range, power consumption, bandwidth, and deployment environment. We can help determine the optimal IoT connectivity method for your use case, including 5G IoT for high-bandwidth applications.
How do you approach IoT data visualization and analytics?
We design data pipelines that collect, process, and analyze device telemetry. Depending on requirements, we implement real-time stream processing, time-series databases, or batch analytics. For IoT visualization, we create custom dashboards using React, Flutter, or industry tools like Grafana—all designed to present complex IoT data in an actionable format for different user roles. Our IoT monitoring software maximizes the value of your sensor data.
Do you provide maintenance and support after deployment?
Yes, we offer ongoing support packages that include monitoring, regular updates, and technical assistance. For IoT systems, continuous maintenance is essential as devices operate in the field for years. Our support includes OTA update systems, performance monitoring, security patches, and help desk services for end-users or administrators.
