Web applications that grow
with your business

15+ years of experience with international companies.

What does web engineering mean at
Felix Schmidt Software?

Web engineering at Felix Schmidt Software means I build the web applications your business works with every day, such as customer portals, booking platforms, or internal tools. Concept, interface, server, and database come from one source, and every stage ends with a version you can try out.

I use widely adopted technology such as TypeScript, Angular or React, and PostgreSQL, so you can still find developers for it in five years. AI tools speed up writing the code. We plan data, workflows, and interfaces together before that starts.

What I build

From platforms for your customers to tools for your team. These are the kinds of web applications I build:

  1. AI-powered web apps

    Web applications with AI built in: assistants answer questions about your documents, and data gets read out of files automatically.

    Chat assistant · Search your own documents · Data from PDFs

  2. SaaS products & MVPs

    From idea to a subscription product billed via Stripe. It starts as a lean first version (MVP), on an architecture built for later growth.

    Multiple customer accounts · Stripe · Scaling

  3. Customer portals

    Give customers a secure place for their data, documents, and orders — self-service instead of email ping-pong.

    Self-service · Documents · Onboarding

  4. Booking platforms

    Appointments, resources, or rentals — booked online, paid online, in sync with your calendar and your team.

    Payments · Calendar sync · Reminders

  5. Internal tools & dashboards

    Replace the spreadsheet chaos: admin panels, dashboards, and workflows tailored to how your team actually works.

    Reporting · Roles & permissions · Automation

  6. Integrations & APIs

    Connect what's separate today: interfaces between your shop, ERP, and CRM, so nobody types the same data twice.

    Interfaces · ERP / CRM · Data sync · AI access (MCP)

Clear ownership.
The right expertise.

Your web application is built under clear technical ownership — from concept to operation. Where additional expertise is useful, I complement the project with experienced senior specialists from my network. For you, the collaboration remains simple: short paths, consistent decisions, and a central point of contact.

Example design: order management for a metal-construction business

Everything from one source

An order-management tool shaped around how a metal-construction business works. Technical specs, inspection protocols, schedules, and documents sit in one place instead of five folders.

Where a project
begins

Fixed prices for the first step, starting from an idea or from a prototype you already built. Analysis and review are credited against the build.

  • Structured review of your requirements
  • Scope for a sensible first version
  • Estimate of effort, risks, and budget
  • Credited in full against the first stage

Prototype Review

  • Code, architecture, data model, and login
  • Security, secrets, and data protection
  • Going live, backups, and what fails with many users at once

  • Credited in full against the production sprint

Production Sprint

Taking a prototype into daily use with customers and staff

from CHF 7’500per sprint

3–6 weeks

  • Keeps what works in your prototype
  • Login, roles, and permissions
  • Database, backups, going live, and error logs
  • Automated tests for the most important flows
  • Larger rebuilds as stages from CHF 15’000

Small, clearly scoped web applications or a first MVP typically run CHF 10’000 to 20’000; a customer portal, an internal business tool, or a booking platform CHF 20’000 to 60’000. Work outside the agreed stage is billed by the hour at CHF 135.

From requirements
to software

Your workflows, existing systems, data, and design decide what the application looks like. AI tools speed up writing the code. Code, documentation, and access belong to you at the end.

Two ways
to work with me

I work with SMEs that need their own web application, and I support product teams for a set period on frontend and architecture.

For SMEs

Your web application.
From idea to operation.

I build your web application from the first idea through architecture and development to launch. You have one contact for every question. Further features get added later in their own stages.

  • Concept, architecture, frontend and backend from one source
  • AI-supported development with automated tests for the most important flows
  • Transparent stages with clearly defined outcomes
  • Code, documentation, and infrastructure fully belong to you
For product teams

Engineering for ambitious web products

I support product teams on complex frontends, technical architecture, and evolving existing web applications.

Engagements are scoped as project blocks or limited hourly retainers, not full-time staff augmentation.

  • Angular frontends for PEAX, DB Cargo, and KulturPass
  • Architecture, code reviews, and technical partnership
  • Part-time collaboration in defined hourly packages, remote first

What clients have said about working with me

Working with Felix was always very pleasant and productive. The greatest value for me came from the speed and quality of his work, as well as his valuable technical insights and design/usability suggestions.

"Extremely quick learner" is the first thought I have when I remember working with Felix. He adapted to working with reactive programming remarkably fast. Both development velocity and code quality quickly raised as he was working with us.

From idea to web application
in four steps

Four steps from the first idea to day-to-day operation. You approve each stage on its own.

  1. Discovery

    We start with your business: goals, workflows, and where things get stuck today. That gives a prioritized scope for the first version. What takes the most work off your team gets built first.

  2. Architecture

    Before any code is written, we plan the data model, system architecture, interfaces, and security concept. Changing these foundations later takes longer than planning them up front.

  3. Build

    I build in short cycles. You regularly get a version you can try out, and you can shift priorities at any time.

  4. Launch & growth

    After launch you get full access to code, infrastructure, and documentation. You decide whether to run the application yourself or keep developing it with me.
