Munich — remote & on-site

Web development and technical integration —carefully planned, cleanly built.

softleb plans, builds and connects digital solutions for independents and small-to-medium businesses. From a new website to the systems behind it — one consistent point of contact, from the first idea to day-to-day operation.

Services

softleb's work spans web development and the systems behind it. The two often meet in the middle — a new website that plugs into existing systems, or a dashboard that finally brings scattered data into one place.

./web-and-solutions/

Web & Solutions

From a company website to a complete web product — designed, built and looked after by one person who owns the whole stack.

Connecting systems that currently run side by side — and setting up new projects on solid technical ground before the first line of code.

  • Interfaces and connectors between applications
  • Custom dashboards for monitoring and reporting
  • Automating data flows and recurring tasks
  • Energy and IoT integration: PV, heat pumps, sensors
  • Technical concept and planning for new projects

Process

Every project is different — the path to it follows a clear, proven sequence. No agency overhead, fast decisions, one consistent point of contact.

  1. 01

    Conversation

    Listen first. We work out the goal, the constraints and the budget — in plain language, without jargon. The result is a shared understanding of what the project should achieve.

  2. 02

    Concept & proposal

    I draft the approach, the technology and the timeline, and bring it together in a binding proposal with a fixed scope. You decide on a clear basis.

  3. 03

    Build

    Built in short, visible steps. You see a working version early and give feedback as it goes — rather than waiting months on a black box.

  4. 04

    Launch & care

    A clean go-live, a clear handover and, on request, maintenance, hosting and further development. A point of contact stays reachable after launch, too.

Fair, market-standard rates. Before a project starts you receive a binding proposal with a fixed scope — no surprises.

Work

A selection of recent work — from a client website through a complete SaaS product to a dashboard for a real heating system.

ketcon.us2026

Full-stack SaaS

A directory and referral platform for the US ketamine-assisted therapy market, connecting prescribing doctors with therapists. Practitioners are checked against official licensing registries, matched to suitable partners, and can propose and manage working relationships directly in the product.

Delivery

From concept to running the service, by one person: React frontend, Express API with Prisma and PostgreSQL — and at the heart of it an automated licence check that validates practitioners against the national provider registry, the federal exclusion list and individual state licensing boards. Alongside it, AI-assisted matching and profile import, real-time messaging, push notifications and an installable app, shipped through an automated build and deployment pipeline.

SaaS platform

A SaaS platform for sharing and managing recipes, with a built-in AI assistant — custom authentication, an image pipeline, search and offline support.

Delivery

Designed, built and shipped end-to-end — full-stack TypeScript with React and Node.js plus an AI assistant for working with recipes, run in containers. Rebuilt and relaunched in 2026 under its own domain.

Client website

A website for a medical practice: service pages, an about section and a contact form in a calm, nature-inspired design.

Delivery

Design and build of the complete website with React and Vite — from information architecture through visual design to go-live.

Monitoring dashboard

A visualisation of a complex heating system: real-time monitoring of every component in one place, privately hosted.

Delivery

Data capture, time-series storage and a dashboard that shows the system's state at a glance — Grafana on InfluxDB, wired to real sensors through Node-RED and MQTT.

About softleb

Behind softleb is Simon Leber — a software engineer with more than seven years of experience building production web applications. From 2018 to 2025 at a Munich software company, responsible among other things for migrating a 250,000-line frontend to modern tooling and building an offline-capable PWA for field service.

Independent since 2025: websites, full-stack products and integration work for independents and small-to-medium businesses. Alongside that, hands-on experience from the family business with photovoltaics and heat pumps — and the software that makes such systems visible and controllable.

What that means for you: you talk to the person who also builds. A direct line, honest assessments, technology without showing off.

FAQ

Answered briefly and directly — what softleb does, how working together looks and what it costs.

  • What does softleb do?

    softleb plans, builds and connects websites and software for independents and small-to-medium businesses. The work covers web development — from a company website to a complete full-stack product — and systems integration: interfaces, custom dashboards, automation, and energy and IoT connectivity.

  • Who is behind softleb?

    softleb is the one-person practice of Simon Leber, a software engineer based in Munich with more than seven years of experience building production web applications. You talk directly to the person who does the work — a direct line, no agency middle layer.

  • What does a project cost?

    Before a project starts you receive a binding proposal with a fixed scope at fair, market-standard rates — with no hidden costs. The exact price depends on scope and requirements and is worked out in a free initial conversation.

  • How does a project work?

    In four clear steps: a conversation to define the goal and constraints, a binding concept with a proposal, the build in short visible steps, and finally launch and operation. On request, softleb also handles maintenance, hosting and further development.

  • Does softleb work remotely?

    Yes. softleb is based in Munich and handles projects both remotely and on site — across Germany, Austria and Switzerland as well as internationally. Enquiries usually receive a reply within one to two business days.
