& AI automation
Simon
Ostermann.
I build web apps, automate the boring parts, and put AI to work where it genuinely helps.
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.
Clean Code
Written once, read a hundred times.
Solid Architecture
Clear boundaries beat a clever system nobody dares to touch.
AI That Earns Its Place
It should make a workflow faster or clearer — or it doesn’t ship.
It Just Works
Pragmatism over over-engineering. Robust beats clever.
Real systems, described in the abstract — each one runs quietly inside a business, saving hours every day.
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.
.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%.
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.
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.
Game-server plugins on .NET 3.5
Started out writing plugins and tinkering server-side. The spark that never left.
IT Specialist · System Integration
Formal grounding in infrastructure, networks and how real systems fit together.
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.
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.
Let’s talk.
Technology, a project, an idea, or just a good conversation — I like exchanges that make things a little clearer.
