Case studies

Anonymized proof, problem, approach, and the result that mattered.

  • Edge AI

    On-device detection with instant alerting

    Problem
    A client needed real-time object detection on a low-cost, battery-friendly camera — without streaming video to the cloud.
    Approach
    Deployed a quantized YOLOv8n model on an ESP32-CAM, publishing detections over MQTT for immediate alerting.
    Result
    Sub-second on-device alerts with no cloud video costs and a fraction of the bandwidth.
  • Computer Vision

    Detection tuned for Nordic winter conditions

    Problem
    Vehicles had to be detected reliably in heavy snow and low light, where off-the-shelf models degrade sharply.
    Approach
    Benchmarked and tuned detection models against a Nordic winter dataset, measuring the accuracy-vs-latency trade-off.
    Result
    Identified the best accuracy/latency configuration for deployment on constrained hardware.
  • Vehicle Networking

    Deterministic real-time pipeline over TSN + 4G

    Problem
    A system needed low-latency, deterministic data transport across in-vehicle and remote links.
    Approach
    Integrated Time-Sensitive Networking (TSN) with a 4G uplink for synchronized, real-time telemetry.
    Result
    Deterministic in-vehicle timing with reliable remote streaming to the cloud.
  • Predictive AI

    Predictive maintenance for HIL test systems

    Problem
    Unexpected hardware degradation in HIL test rigs caused unplanned downtime during ADAS validation.
    Approach
    Built predictive-maintenance models on test-system telemetry to flag early degradation, integrated into existing HIL workflows.
    Result
    Earlier fault detection and reduced unplanned downtime for the test infrastructure.
  • Sensor Fusion

    Indoor localization with BLE and sensor fusion

    Problem
    Indoor positioning needed higher accuracy than signal-strength (RSSI) alone could deliver.
    Approach
    Fused BLE 5.2 RSSI fingerprinting with Angle-of-Arrival data through an ANN model.
    Result
    Improved localization accuracy across varying network and environmental conditions.
  • Automotive Test

    End-to-end HIL rig for safety-critical bus systems

    Problem
    Safety-critical vehicle systems needed automated, repeatable verification before deployment.
    Approach
    Designed and commissioned HIL rigs end-to-end — from physical build to NI VeriStand test environments and custom control GUIs.
    Result
    Automated validation aligned with automotive safety and quality standards.
  • TinyML

    Always-on TinyML sensing on a microcontroller

    Problem
    A product needed always-on recognition on a battery-powered microcontroller, with no cloud connection.
    Approach
    Trained and quantized a compact neural network, deploying it with TensorFlow Lite Micro on an ESP32 / STM32-class device.
    Result
    Real-time, offline inference within tight memory and power budgets.
  • GUI & Tooling

    Desktop GUIs for hardware control and test

    Problem
    Engineers needed a simple desktop interface to configure, control, and monitor test hardware — without touching low-level scripts.
    Approach
    Built control GUIs in C# and Python that drive the hardware over serial/CAN and visualize live data in real time.
    Result
    Faster, repeatable test setup with live control and monitoring from a single interface.
  • Firmware

    Portable bare-metal firmware across MCU families

    Problem
    A product line needed consistent low-level drivers across several microcontroller families.
    Approach
    Wrote portable C/C++ bare-metal firmware and BSP/drivers (SPI, I2C, UART, CAN) targeting STM32, ESP32, Texas Instruments, Arduino, Raspberry Pi/Pico and Odroid.
    Result
    A reusable driver layer that brings new boards up quickly with minimal rework.
  • RTOS Firmware

    Real-time firmware on FreeRTOS across microcontrollers

    Problem
    Time-critical tasks needed deterministic scheduling on constrained hardware.
    Approach
    Developed C/C++ real-time applications on FreeRTOS, deployed across STM32, ESP32, Raspberry Pico and Arduino-class devices.
    Result
    Deterministic task timing and stable long-run operation on low-power hardware.

About

zaramTech AB is a boutique engineering consultancy spanning the full path from silicon to cloud — embedded firmware, HIL/SIL automotive test, on-device edge AI, and full-stack software.

Behind it is 10+ years designing, integrating, and validating embedded and automotive software. At Volvo Buses, that means building Hardware-in-the-Loop rigs end-to-end and the automated test infrastructure — NI VeriStand, TwinCAT, and Aliaro SIL — that validates safety-critical vehicle systems.

That deep firmware, RTOS, and vehicle-networking background is paired with applied AI/ML research — including a quantized YOLOv8n detector deployed on an ESP32-CAM via TFLite Micro for real-time, offline, on-device detection.
