Quick answer

What we build

Who it is for
Connected-product teams that need a secure, maintainable backend for a device fleet.
Typical timeline
6–12 weeks
Typical cost
$5,000–$15,000 for a basic telemetry dashboard on managed cloud services; $25,000–$80,000+ for a full fleet-management platform with OTA campaigns, alerting, analytics and role-based access. Source: IoT development cost guide.
Tools and technologies
AWS/Azure/GCP, MQTT ingestion, REST/GraphQL APIs, Time-series databases

Every project is quoted as a fixed-scope proposal within 3–5 business days of a discovery call. Discuss your product

Capabilities

What we deliver

Provisioning and identity

Per-device X.509 certificates or secure-element credentials injected at manufacture, zero-touch registration and role-based access for operators and customers.

MQTT and API ingestion

Telemetry ingestion through AWS IoT Core, Azure IoT Hub or a self-managed MQTT broker (EMQX, HiveMQ), with versioned message contracts and offline buffering.

Time-series storage

Hot, warm and cold storage tiers on TimescaleDB, InfluxDB or Amazon Timestream for InfluxDB, with retention and downsampling agreed per data type.

OTA coordination

Staged firmware campaigns by device cohort, signed images, progress reporting and rollback, coordinated with the firmware's A/B update scheme.

Fleet dashboards

Fleet health, alerts and remote actions for operations teams, load-tested to the agreed device count.

Capabilities and deliverables

Key areas of focus

  • Scalable cloud architecture design
  • Optimized data storage and processing
  • Efficient backend API development

Deliverables

  • Secure cloud infrastructure
  • Scalable backend solutions
  • Comprehensive data management tools

Process

How we work

  1. Interfaces and contracts

    Agree device identity, message formats, timestamps, units and version compatibility across firmware and cloud teams.

    Deliverable: Versioned device API and telemetry contracts

  2. Architecture

    Choose a modular application or separate services according to deployment, ownership and scaling needs.

    Deliverable: Architecture with monitoring, backup, access control and incident ownership planned

  3. Build and integration

    Exercise the complete device-to-dashboard workflow, including offline devices, permission failures and recovery.

    Deliverable: Working application with access permissions tested for each user role

  4. Release and handoff

    Hand over source and deployment access, configuration documentation, dependency licences and repeatable build instructions.

    Deliverable: Release package; hosting, source ownership and support agreed

FAQ

Frequently asked questions

Working with Rapid Circuitry

How much does a project cost, and how is pricing structured?

Each project is quoted as a fixed-scope proposal: a statement of work with milestones, deliverables and pricing, sent within 3–5 business days of the discovery call. The price depends on the requirements, how mature the design is, technical complexity, the number of prototype iterations and the validation scope. Longer engagements can also run as a retainer or a hybrid of both. For budgeting before you contact us, our hardware development cost benchmarks and the PCB design, firmware and IoT cost guides give indicative ranges with their assumptions stated. They are planning ranges, not quotes.

How long does a project take?

It depends on the scope and on what already exists when we start. As planning ranges from our cost benchmarks: a single PCB layout takes 2–6 weeks per board and embedded firmware 4–16 weeks. A connected (IoT) product takes 3–12 months from concept to a production-ready design, and a regulated medical device 12–24 months to a 510(k) submission-ready package; from idea to mass production, a typical connected product takes 9–18 months. The proposal sets out a dated milestone plan, and you receive weekly progress updates during the project.

Who owns the intellectual property?

You do. Our contracts assign the intellectual property in the project work product (schematics, PCB design files, firmware source code and documentation) to you on payment, and we hand over the source files, not only fabrication outputs or compiled binaries. The exact terms are set out in the signed agreement for each engagement.

Do you sign NDAs?

Yes. We sign a mutual NDA before any technical discussion of your project. Send your standard NDA or use ours; we return it signed within one business day.

Can you work with clients in the US, Europe and Japan?

Yes. We are based in Hyderabad, India, and work with product teams in India, the United States, the United Kingdom, Germany, Japan, Australia, the Middle East and other markets. Our office hours are 10:30–19:00 India Standard Time (UTC+5:30), Monday to Saturday, and we schedule design reviews across time zones, typically from US Pacific to Central European time. Japan is 3.5 hours ahead of India, so our first four hours overlap the Japanese afternoon. Prototypes and documentation ship by international courier such as DHL or FedEx. Our hardware outsourcing guide covers what to agree before an international project starts.

Do you hand off to manufacturing, and which contract manufacturers do you work with?

Yes. We prepare the manufacturing release package — fabrication and assembly drawings, the BOM with approved manufacturers, programming files and test specifications — and hand it over to the contract manufacturer (EMS) you choose. If you have not chosen one, we help you evaluate candidates through technical capability assessments and a pilot build. See manufacturing support.

Are you ISO 9001 or ISO 13485 certified?

No. Rapid Circuitry does not hold ISO 9001, ISO 13485 or other certificates. Our processes are aligned with ISO 9001:2015, and we design products to the requirements of the standards that apply to them — for example IEC 60601-1 and IEC 62304 for medical devices (with design documentation structured so your ISO 13485 quality system can absorb it) and IEC 61000 for EMC — and we specify IPC-A-610 workmanship classes for assembly. We prepare the product and its documentation for certification testing at accredited laboratories; the certificate or approval is issued for your product by the laboratory, notified body or regulator.

What do you need from me to start?

A short, non-confidential description of the product and what it must do (sensors, connectivity, on-device processing), the target production volume and unit cost, the markets and regulations it must meet (for example FDA, CE or FCC), your timeline, and what already exists: a concept, a proof of concept, schematics, PCB files or firmware. After the NDA, the next step is a 30-minute discovery call with the engineers who would work on the project, followed by the fixed-scope proposal. Send a project brief to begin.
