Software Developer

Backend, interfaces and system integration – reliable in day-to-day operations.

I help companies build and stabilize business-critical software – from backends and interfaces to web platforms.
Focus: clean data flows, performance/SEO and operations that stay reliable after go-live.

Profile

Senior-level delivery with a focus on backend, integration and operations – structured, robust and traceable.

I’m Fabian Georgi. I’ve been building software for over 18 years – as a freelancer, as the managing director of my own software agency, and in agency and industrial environments. That means: fast delivery, without sacrificing the fundamentals that keep maintenance and operations under control later on.

I’m strongest where systems have to work together: interfaces, data models, synchronization and integrations between web, shop and ERP/inventory systems. Web development is also a strong focus: complete websites and platforms in WordPress/TYPO3 or as a static site (e.g. Eleventy) – with a focus on updatability, security, performance and SEO. Because of my entrepreneurial background, I understand not only the technical but also the business side of software projects. Effort, risk and maintainability are always part of the decision-making. I work in a structured, pragmatic way with a clear view of long-term operations. The goal isn’t the fastest solution, but one that remains solid for years.

Typical focus areas

Interfaces that are clear and reliable Integration: shop ↔ ERP ↔ CMS Data models & synchronization Performance/SEO & Core Web Vitals Operations: deployments & monitoring

How I work

  • Implementation with a focus on operations, edge cases and transparency
  • Documentation when needed: interface docs, README, runbooks
  • Delivery readiness: CI/CD, reproducible deployments
  • No unnecessary complexity – but clean boundaries

Services

Core focus on backend and integrations – complemented by web platforms and digital projects when it makes sense for the overall scope.

Backend & interfaces

Design and development of stable backend systems and interfaces – clearly structured, documented and reliable in production.

  • Clear interfaces and consistent data formats
  • Access and permission concepts aligned with real needs
  • Clean error handling, logging and stable processes

System Integration & Middleware

When systems need to work together: ERP, shop, CMS, CRM. I build data flows and interfaces that run reliably and stay maintainable over time.

  • Clear data flows and ownership (who is the source of truth?)
  • Reliable processing: traceable, fault-tolerant, reproducible
  • Clean handover: documentation, checks, and a process for fixes

Operations & delivery

So systems run reliably and releases are predictable: infrastructure, deployments and clean operational processes.

  • Linux servers, Docker, reverse proxy, TLS/DNS
  • CI/CD, reproducible deployments, rollback strategies
  • Migrations (hosting/DNS/TLS) with a focus on minimal downtime

Web Platforms & Digital Projects

Websites and portals built to last: clean structure, fast, updatable — and, if needed, connected to your existing systems.

  • Company websites, landing pages, portals, internal tools
  • Performance & SEO basics: fast load times and solid structure
  • Taking over existing setups: stabilize, update, establish clear deployments

Campaigns & Lead Processes (optional)

If you want, I can support the project all the way into go-to-market — with one main point of contact. Execution happens in the background with my network.

  • Email campaigns: setup, templates, automations, reporting
  • Lead processes: forms, tracking, CRM handover, follow-up
  • Google Ads: structure, landing pages, measurement, ongoing maintenance

Typical projects

  • Shopify/shop system ↔ ERP (inventory, prices, documents, products).
  • TYPO3/WordPress ↔ backend/CRM/SAP (forms, content, data pipelines).
  • API modernization: versioning, security, performance, clean error handling.
  • Technical takeover: stabilization, updates, hardening, release processes.

References

A selection of typical projects and outcomes. Details can be discussed depending on NDA.

Middleware for product data & inventory (shop/ERP)

PHP 8 · REST/GraphQL · MySQL · JWT · Shopify · ERP

Internal web tool for managing product master data and inventory. Clear interface approach, role/permission concept, synchronization with the shop and bidirectional ERP integration. Documentation via OpenAPI/Swagger.

ERP integration SAGE100 (inventory, documents, logistics)

MSSQL · Python · REST · Automation

Data integration solution between SAGE100 and middleware: processing inventory levels, sales documents and logistics data (delivery notes/tracking). Automated data preparation and transfer via REST interfaces.

TYPO3 ↔ SAP S/4HANA interface

TYPO3 · PHP · REST · Middleware · Performance

TYPO3 extension to synchronize SAP forms with a web platform. Bidirectional interface and performance optimization for large datasets using middleware approaches.

Industry: AI-assisted quality control (smart camera)

Python · C++ · TensorFlow/Keras · MQTT · InfluxDB · Docker · CI/CD

Development of an application for automated defect detection in assembly using AI-based image processing. Integration into production processes, data logging and operation in production-like environments.

Hosting migration & release processes

Linux · Docker · CI/CD · DNS/TLS · Hardening

Migration and stabilization of production systems including deployment workflows, security measures and downtime minimization. Goal: predictable releases, reproducible operations and clear responsibilities.

Long-term operation of a large community platform

Operations · Performance · Maintenance · Migrations

Setup and long-term operation of a community platform (incl. golf2forum.de) including maintenance, further development and performance improvements over many years.

Web platforms & company websites with technical substance

TYPO3 · WordPress · Static sites · Performance · SEO · Operations

I also deliver complete websites and company sites – with a clear technical focus. What matters to me are clean structures, updatability, performance and reliable operations over many years. I prefer web projects where content, data sources or business processes are connected – not purely marketing pages without technical depth. Typical topics include relaunches of grown sites, technical takeovers, performance optimization or integration into existing system landscapes. In short: web projects treated like software – not disposable products.
