Build brave.
Ship real.

Potamus Labs designs and builds dependable software, embedded systems, and electronics—from the first useful prototype to a product ready for the real world.

What we build

One lab. Multiple layers of the stack.

We work where software meets hardware, keeping the system view intact instead of treating every discipline as a separate hand-off.

01

Software engineering

Purpose-built applications, services, APIs and internal tools with maintainable architecture and pragmatic delivery.

  • Web & product software
  • APIs & integrations
  • Automation & tooling
02

Embedded systems

Firmware and connected systems designed with the physical product, timing constraints and field behaviour in mind.

  • Firmware architecture
  • Device communication
  • Bring-up & debugging
03

Electronics

Electronic concepts and prototypes that turn an idea into something tangible enough to test, learn from and improve.

  • Rapid prototyping
  • System integration
  • Hardware / software validation

Demos

Working examples, grouped by what they prove.

Small public builds that show concrete interfaces, integrations and product ideas. Some are polished tools; some are deliberately narrow demonstrations of one useful path.

Simple web apps

Browser-first tools that run without a backend.

Web Serial · Google Fit Live

Veroval BPM25 Sync

Downloads saved blood-pressure readings from a Veroval BPM25 over USB in desktop Chrome or Edge, keeps the archive in the browser, exports CSV, and can optionally sync selected readings to Google Fit.

  • No backend or account database
  • Local-first storage and explicit Google consent
  • English and Slovak UI

Full-stack products

Live apps with accounts, APIs and real workflows.

React · Rails · Finance Live beta

Moolance

A free recurring-expense tracker for subscriptions, memberships, bills and income. Moolance helps people see their monthly burn, pause or cancel wasteful spend, and watch projected savings climb without spreadsheet gymnastics.

  • Track recurring expenses and income by frequency
  • Pause or cancel subscriptions and calculate annual savings
  • Tags, badges, import/export and multilingual UI

How we work

Serious engineering.
Without the theatre.

Good products come from understanding the actual constraint, proving the risky parts early, and keeping decisions legible. We prefer working systems over impressive diagrams.

Start with the problem →
  1. 01

    Understand

    Clarify the user, environment, interfaces and constraints before committing to a solution.

  2. 02

    Prototype

    Build the smallest thing that can retire the biggest uncertainty and generate real evidence.

  3. 03

    Engineer

    Turn what worked into a maintainable system with explicit trade-offs and sensible failure modes.

  4. 04

    Ship & learn

    Get it into the real world, observe what happens, and improve from facts rather than assumptions.

Complex enough to matter.
Simple enough to understand.
Robust enough to ship.
