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.

Four disciplines, one system view — from the architecture of a service to the channel it is published on, instead of treating every discipline as a separate hand-off.

01

Software & systems engineering

System architecture, design and code: purpose-built applications, services and tools that hold up in the real world.

  • System architecture & design
  • Applications, platforms & APIs
  • Automation & tooling
02

Production & operations

Taking services live and keeping them trustworthy: deployment, security, telemetry and diagnostics as part of the build, not afterthoughts.

  • Deployment & hosting
  • Security & hardening
  • Telemetry, diagnostics & recovery
03

Embedded, firmware & electronics

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

  • Firmware & embedded control
  • Electronics & PCB design
  • Bring-up, integration & validation
04

Content & social management

Video and social channels run end-to-end for customers: content prepared and published, rights protected, audience reached.

  • Video production & publishing
  • Copyright & Content ID claims
  • Social channel management

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

Custom-built tools

Tools built around one customer's work.

Online tool · React · TypeScript Live

Tile Layout Planner

An online tool for planning tile layouts in irregular rooms. Draw the room as a freeform polygon, set the tile size and grout width, pick a pattern, and see the layout, tile count, a cut list, and a reuse plan for the offcuts — before anyone starts cutting.

  • Freeform room editor — draw any polygon, then drag points, with coordinates and wall lengths labelled
  • Straight lay, running bond and herringbone patterns
  • Tile count split into full tiles, cut tiles and estimated waste
  • Cut Inventory — every cut piece grouped by identical shape, with measurements in mm
  • Reuse Plan — one-cut pieces at any angle, kerf accounted for in mm, so offcuts get reused instead of thrown away
  • Adaptive grid — major and minor lines that rescale as you zoom, with an on-canvas scale chip
  • Saved Rooms — save and load rooms in the browser, export and import them as JSON
  • Runs entirely in the browser — no account, no uploads, nothing leaves your device

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.
