Backend & API Development
Design and ship dependable application backends, internal platforms and APIs that do not collapse under real workflows.
- Python-first system design
- Django, DRF and FastAPI delivery
- Maintainable service boundaries
Vienna-based Python consultant for Austria and Europe Senior IC delivery for selected projects
Backend systems for real operations, not fragile demos.
I help SMBs, agencies and product teams replace fragile manual work with dependable APIs, internal tools, scraping pipelines and AI-assisted workflows.
English-first delivery, Austria-aware positioning, direct founder contact and a bias toward systems that survive real operations.
Scope APIs, automation layers, internal tools and data-heavy product workflows
Working mode Direct execution, practical scoping and systems that still make sense after handover
Buyer fit SMBs, agencies and product teams with a real operational bottleneck
German-language discovery is welcome. Delivery, implementation and technical workshops are currently English-first.

Featured case
Proof should feel operational before it feels promotional
The strongest public trust signal is still system shape: constraints handled well, workflows compressed and a build that looks usable before anyone talks about aesthetics.
Private Austria-focused data product

Services
A sharp offer built around backend leverage
The core offer is backend delivery and automation. Data acquisition, AI agents and selected frontend work support the business outcome instead of diluting the positioning.
Business Automation & Integrations
Replace fragile manual workflows with reliable data movement, alerts, sync jobs and internal operator tooling.
- Workflow and bottleneck mapping
- Sync jobs, webhooks and task queues
- Admin-first operating tooling
Web Scraping & Data Pipelines
Build targeted data acquisition pipelines, enrichment flows and exports for research, outreach, market mapping and internal products.
- Research-driven source planning
- Structured enrichment and exports
- Operable pipelines with presets
AI Agents & Internal Workflows
Use AI where it removes repetitive review, routing or classification work, without pretending that a prompt replaces system design.
- AI placed inside operational systems
- Human review and fallback paths
- Prompt logic backed by product structure
Selected work
Additional case studies with product and delivery depth
The strongest signal here is not glossy design. It is system shape, technical depth, workflow compression and honest operating constraints.
Creator Discovery & Qualification Pipeline
A private multi-platform pipeline for influencer discovery, AI-assisted evaluation and outreach-ready data.
- Seven-step processing pipeline across multiple content platforms
- Contact extraction and AI-assisted filtering built into one flow
Subscription and Payments Backend
A public Django REST project that combines business logic, borrowing workflows, Stripe billing and task automation.
- Stripe integrated for rental and fine payments
- Borrowing workflow and reminder automation in one system
Process
A delivery model built around the real operating bottleneck
Most projects do not need more software. They need a narrower system, clearer states and less repeated manual effort.
Audit the bottleneck
Map the workflow, integrations and failure modes before committing to a build.
Design the narrowest useful system
Scope APIs, data flow, automation boundaries and the smallest version that creates business value.
Ship with operations in mind
Deliver monitoring, documentation, admin tooling and handover material together with the code.
Insights
Practical writing for buyers and operators
The blog is built around buying decisions, implementation tradeoffs and operational reality instead of generic thought leadership.
What an AI agent can actually own inside a small business workflow
A practical boundary for AI agents in operations, with emphasis on routing, drafting and first-pass review instead of vague autonomy claims.

Answers that matter before the first call
The site is built to attract qualified inbound, so the core constraints and fit are visible early.
What kind of clients are the best fit?
Austria- and EU-based SMBs, agencies and product teams that need dependable backend delivery, integrations, workflow automation or AI-assisted internal tools.
Do you take German-speaking projects?
Yes for discovery and written context. Delivery, technical workshops and implementation are currently English-first.
Do you also build frontend?
Yes when it supports the product outcome, especially dashboards, portals and conversion-focused landing pages. The core value I sell is still backend, automation and system design.
Can you work with private client codebases?
Yes. Several representative case studies are anonymized because the original repositories and business data are private.
Start a project
If the bottleneck is real, the system should become simpler after I touch it.
Bring the workflow, the current stack and the business constraint. The first step is a practical scope, not a vague discovery sprint.
