Independent software engineering

Software for devices, systems, and teams that cannot afford guesswork.

AMEBA Technologies develops robust software with a clear focus on medical device software, Linux and FreeBSD systems, backend services, desktop software built with Qt, Slint, or VCL, and other technically demanding products. Core technologies are Rust, C/C++, and Python, backed by decades of cross-domain engineering experience. This also includes the careful, controlled use of AI, and a willingness to clean up vibe-coding derailments before they turn into production problems.

  • Medical-device direction Navigation, device integration, sensor data, UI, and safety-relevant thinking.
  • Systems depth From bare metal and USB to async services, protocol work, and production tooling.
  • Defence experience Project work in the arms industry and military requirements engineering for security-sensitive systems.
  • Direct collaboration Direct communication and senior engineering judgment from architecture to implementation.
Focus areas

A small company with senior-level engineering range.

AMEBA Technologies offers senior-level engineering with short feedback loops and hands-on delivery. The current positioning is intentionally aimed toward software for medical devices and adjacent high-reliability domains, including defence-related work.

Medical devices

Software that supports devices, workflows, and operators.

Experience includes navigation software for a TMS machine, sensor integration via USB, 3D-guided user interfaces, and development choices shaped by precision and patient-facing context.

Rust USB Linux FreeBSD Slint
Systems software

Close to the metal when the project needs it.

Firmware-adjacent work, protocol analysis, sockets, USB, custom integrations, debugging, and native development across Linux, FreeBSD, macOS, Windows, and embedded targets.

C C++ Assembler Protocols
Backend and tooling

Reliable services without unnecessary complexity.

Backend services, APIs, monitoring, data processing, migration work, and practical infrastructure for teams that need things to keep running.

Python PostgreSQL FastAPI Docker FreeBSD jails
Selected work

A draft selection that already supports the med-tech narrative.

The projects below are drawn from recent freelance work and highlight the combination of medical-device context, systems programming, and practical software delivery.

2024 - ongoing

Navigation software for a TMS machine

Medical device | Rust | Slint | USB | Linux

Development of navigation support for transcranial magnetic stimulation equipment. The software combines precise sensor input, spatial visualization, and an operator UI designed to help position the coil accurately.

2025

Scala-to-Python migration for API and data tooling

Hosting | Python | FastAPI | PostgreSQL

Porting of a REST API and a stored-procedure generator from Scala to Python. This is the kind of delivery work where speed matters, but correctness and maintainability still need to stay visible.

2023 - 2024

Rust backend and websocket services

Backend systems | Rust | tokio | PostgreSQL | htmx

Implementation of backend services for monitoring and near-real-time communication, including a websocket server and HTML-oriented service logic. Strong example of Rust in production systems outside the embedded space.

2023 - 2025

Defence-related systems and requirements work

Defence | Python | protocol work | requirements engineering

Recent defence projects include a peer emulator in the arms industry and requirements engineering for a military communication system. Together they underline experience in security-sensitive, protocol-heavy, and high-reliability environments.

Broad experience

Cross-domain engineering with regulated and safety-relevant exposure

Medical devices | Defence | Pharma | public sector | embedded | native software

The wider profile spans medical devices, defence, pharma, public administration, finance, logistics, communication systems, and hardware-near development. That breadth is useful when products have to interface with the real world instead of living inside a generic web stack.
