What we do

Our services

We design and build complete technological solutions — from the first schematic to the cloud dashboard. No off-the-shelf products, everything custom.

Embedded Systems

Custom firmware and real-time software for microcontrollers and microprocessors (STM32, ESP32, NRF52, RISC-V, and more). From bare metal to RTOS.

IoT & LoRa

Connected device networks, LoRaWAN architectures, MQTT gateways, and end-to-end IoT solutions designed for reliability and low power consumption.

Custom Hardware

PCB design, schematic capture, component selection, and prototype-to-production support. We design the exact hardware your project needs.

Cloud Software

Backend APIs, real-time dashboards, data pipelines, and cloud infrastructure tailored to your IoT ecosystem or industrial application.

Sensing & Instrumentation

Custom sensor integration, signal conditioning, ADC design, and data acquisition systems for industrial, environmental, and scientific applications.

Technical Consulting

Technology assessment, architecture review, feasibility studies, and technical due diligence. We help you make the right technical decisions from day one.

Our process

How we work

A clear process, no surprises. We work closely with you at every step.

We understand the problem

We start with a deep technical conversation. We listen to your challenge, ask the right questions, and make sure we fully understand what you need before we propose anything.

We design the solution

We propose a concrete technical plan: architecture, technologies, timeline, and cost. You validate every decision before we write a single line of code or draw a trace.

We build it

We develop hardware and software in parallel, with regular updates and live demos. You always know the current state of the project — no black boxes.

We deliver & support

Delivery includes full documentation, source files, and a transition period. We don't just hand it over — we make sure it works in your real environment.

Why us

Not consultants.
Engineers.

We've built real products, shipped real hardware, and debugged at 3am. We bring that experience directly to your project.

Real field experience

Our team has shipped products from prototype to mass production. We know what works under real-world constraints.

Full-stack hardware + software

From PCB layout to cloud API, we cover the entire stack. No coordination overhead, no finger-pointing between vendors.

100% custom solutions

We don't sell off-the-shelf platforms with your logo on them. Every project is designed from scratch for your specific requirements.

Direct communication

You talk directly to the engineers building your product. No account managers, no ticket systems, no middlemen.

The team

Small team,
big expertise.

We're a small, agile team of engineers based in Seville, Spain. No layers of management — just experienced engineers who care deeply about building things that actually work.

Mekriva was born from the belief that companies deserve a technical partner who speaks their language and is genuinely invested in their success — not a vendor that disappears after the invoice.
