About Anton

Senior Backend & System Consultant for digital implementation instead of theory

I support companies in German-speaking countries in digitizing internal processes, automating recurring work, and building scalable backend or AI solutions. I don't work like a classic agency with long concept phases, but pragmatically, goal-oriented, and with a focus on measurable results.

My technical foundation lies in Node.js, NestJS, and scalable architectures with microservices, Docker, PostgreSQL, and Redis. At the same time, I develop productive AI integrations such as GPT-based internal assistants, automations with n8n, or RAG bots that intelligently extend existing systems like CRM, ERP, or support processes. I also assist companies working with blockchain or digital payment systems with Web3 integrations, automated billing, or monitoring with high transaction volumes.

Clients I work with particularly appreciate that I don't just deliver code, but independently analyze processes and propose optimized workflows that can be directly translated into a company's daily operations and figures. My approach is clear: less manual work, less complexity, more automation – implemented with production-ready quality and without unnecessary loops.

Ideal projects are those where not just "more developer capacity" is sought, but someone who takes responsibility for a technical area, can make decisions, and builds solutions that scale and remain maintainable in the long term. If a company is serious about starting with AI, automation, or modern backend systems and is looking for a reliable implementation partner, I am the right person.

Experience

  • Brumecore
    Senior Backend Developer
    January 2024 - Today (2 years and 7 months)
    BrumeCore is a small, highly specialized tech unit based in Austria that supports companies not only in digitizing processes but in fully automating them and building scalable systems. The focus is on individual backend architectures based on Node.js/NestJS, integrations of payment and blockchain systems, as well as AI-supported workflows with GPT, RAG, and n8n. We deliberately work without "agency overhead" and implement projects directly and pragmatically – with clear technical responsibility and measurable results for the client. Typical clients are SMEs in the DACH region who want to accelerate internal processes, automate support, or build their own digital products.

  • Flex International

    January 2020 - January 2024 (4 years)
    At Flex International, I was responsible for developing internal tools and web applications to automate operational processes. The focus was on building backend and frontend systems to optimize workflows in daily business – including automated data processing, internal dashboards, notification systems, and digital interfaces for teams and administration. The goal was to reduce manual work steps, make processes measurably more efficient, and map processes in a scalable and maintainable way. The solutions were used in production and directly integrated into the company's daily operations, significantly reducing internal processing times.
