Three tracks, one deliverable: a working prototype

Fixed-scope engagements only. Each track ends with sources, builds and a handover note that a third party can pick up.

Track

Firmware & Embedded

Bare-metal and RTOS firmware for ESP32 and STM32, from drivers to radio stacks.

  • ESP32: Wi-Fi, BLE, OTA, low-power modes
  • STM32: HAL/LL, DMA, timers, USB
  • Sensor and bus integration (I2C, SPI, UART, CAN)
  • Deterministic test harness and reproducible builds

Track

PCB Design & Hardware Engineering

Schematic capture, layout and bring-up for small-batch prototypes.

  • 2-4 layer boards with impedance-aware routing
  • Power tree and decoupling review
  • DFM pass for the chosen fab house
  • Bring-up, rework and measurement

Track

Cross-platform Apps

React Native and Electron/React clients for devices and dashboards.

  • BLE and serial transport layers
  • Desktop tooling for provisioning and logs
  • Data visualisation for telemetry
  • Store and installer packaging

Process

Idea to handover

Five stages with explicit entry and exit criteria.

  1. 01

    Idea

    One paragraph, one constraint list, one target date.

  2. 02

    Validation

    Feasibility, BOM sanity, risk register.

  3. 03

    Prototype

    Schematic, board, firmware, control app.

  4. 04

    Test

    Bring-up, measurements, regression harness.

  5. 05

    Handover

    Sources, builds, flashing and maintenance notes.

Boundaries

What we do not take on

  • Mass production and certification campaigns
  • Consumer product compliance (CE/FCC) as a prime contractor
  • Legacy codebase rescue without an owner-side technical contact
  • Hardware sourcing without an engineering scope

Not sure which track fits?

Send one paragraph about the device and the deadline. The answer is either a scoped plan with a price or a clear no-go with the reason.
