Custom software development for companies: internal tools, web applications and AI integration — one dedicated contact, a scalable engineering team.
A complete platform built solo: native app for hosts, digital guide in the browser for guests. Product design, apps, backend, payments, realtime — the full range, live in the stores.
UPS invoice data in, finished customer re-invoices out — matching and fee included. A recurring billing process that now runs without manual work.
Tailor-made software when off-the-shelf tools do not fit your processes — from written specification to documented handover.
Replace Excel sprawl, connect isolated systems — typically: three systems become one interface.
Browser-based, no installation, on every device — from customer portals to booking systems.
Implementation instead of slide decks: LLMs and RAG integrated into your existing systems, GDPR-compliant.
Web data as a service from Germany — price monitoring to dataset creation, GDPR-fluent.
From idea to usable product in 8–12 weeks — with an honest fixed-price frame.

Bauer IT Solutions is an owner-led engineering practice for custom software development, based in Rodgau near Frankfurt, Germany. Companies hire me when off-the-shelf software no longer fits their processes: when spreadsheets have quietly become databases, when three systems refuse to talk to each other, or when a portal is missing that takes customer requests around the clock. Instead of an agency apparatus, you get one dedicated contact: the engineer who understands your requirements and owns the architecture — backed by an established engineering team that scales in for larger builds, parallel projects and ongoing maintenance.
The scope ranges from internal tools that replace spreadsheet sprawl and customer portals and booking systems to GDPR-compliant AI integration into existing systems. Web data is part of it too: price monitoring and data extraction as a service, delivered from Germany with a German contract. References from optics, fleet management and real estate are documented in the project sheets.
Every project follows the same process: free initial consultation, written specification, no-obligation fixed-price quote — then development in weekly visible builds on a staging environment. The source code and documentation are yours at the end. Honest pricing ranges are public; the collaboration itself is documented under how I work.
For international clients the collaboration is fully remote-capable — contracts in English or German, CET time zone, hosting in Frankfurt if you want a GDPR-native setup without vendor lock-in.
You do, completely. Code, documentation and all credentials are transferred at handover — you are never locked in.
Twofold: behind me stands an established engineering team I can bring in at any time — for large builds as well as ongoing maintenance. And every project is built for handover: written specification, documented code, staging environment. You are never dependent on a single person.
Free initial consultation, then a written specification with a fixed-price quote. Development in weekly visible builds on staging, ending with a documented handover.
Smaller internal tools start in the mid four-figure range; web applications and customer portals sit above that depending on scope. After a free initial consultation you receive a written fixed-price quote — honest orientation ranges are published on the pricing page.
A focused internal tool is typically in production within four to eight weeks; web applications and MVPs within eight to sixteen weeks. The written specification contains the concrete timeline — including weekly visible builds.
Yes. Collaboration is fully remote-capable with contracts in English or German, CET time zone. On-site meetings are available in the Frankfurt Rhine-Main area; hosting can stay in Frankfurt for GDPR-native setups.
A free initial consultation to clarify requirements, feasibility and an honest cost range — then you decide.
