Ostermann.

I build web apps, automate the boring parts, and put AI to work where it genuinely helps.

(01)  About

I’m a full-stack developer and trained IT specialist for system integration, currently working toward my Master’s in Business Informatics at the University of Oldenburg.

I like the place where software, infrastructure, automation and AI meet — simplifying workflows, connecting systems that never talked before, and finding practical ways to use AI for work that actually matters.

Linux feels like home and Python is my go-to. I’m a firm believer in open source, and I push to bring it into the companies I work with wherever it fits.

(02)  How I build
01

Clean Code

Written once, read a hundred times.

02

Solid Architecture

Clear boundaries beat a clever system nobody dares to touch.

03

AI That Earns Its Place

It should make a workflow faster or clearer — or it doesn’t ship.

04

It Just Works

Pragmatism over over-engineering. Robust beats clever.

(03)  Selected work

Real systems, described in the abstract — each one runs quietly inside a business, saving hours every day.

01
Automation
Python · OCR · ERP

Order Intake on Autopilot

Incoming order emails get read automatically — line items, documents and drawings land in the ERP on their own. Orders with hundreds of positions that once took days are now in the system in minutes, without a single typo.

02
Web app
.NET · Reporting

A Paper Process, Digitized

Turned a paper-based inspection and defect workflow into a web app with automatic reporting. Management gets live figures on tap, and processing time dropped by more than 60%.

03
Strategy
Consulting · Process

Long-Term Digitalization Partner

Standing beside businesses as a strategic partner — mapping processes, picking the right tools and automating what matters. On average around 30% lower costs and noticeably faster workflows.

(04)  The stack

Useful in production, not just in demos.

I work across the stack. What I love most is when systems, infrastructure, code and apps mesh together — performant, reliable, and simply working.

(05)  How I got here
Early days

Game-server plugins on .NET 3.5

Started out writing plugins and tinkering server-side. The spark that never left.

Training

IT Specialist · System Integration

Formal grounding in infrastructure, networks and how real systems fit together.

Now

Master’s & self-employed with Tosimo

Two things at once: working toward my Master’s in Business Informatics at Uni Oldenburg, and building Tosimo with a good friend — web apps and automation for real businesses.

Next

Deeper into AI agents

Pushing LLM integrations and agents from experiments into dependable, production workflows.

The best work is the kind that quietly removes itself.

(06)  Say hello

Let’s talk.

Technology, a project, an idea, or just a good conversation — I like exchanges that make things a little clearer.
