Martin Schiller

I'm a freelance software and DevOps engineer working remotely with German and international clients since 2021. I build business automation, data platforms, web and Android apps, and C/C++ systems software, and I take projects from requirements through deployment and maintenance.

Recent work:

• Erfolgswerk.ai (Jul 2026 – present), DevOps Engineer & Odoo Specialist: I automate order processing end to end with n8n pipelines that connect Odoo ERP to external services and APIs, build custom Odoo modules for sales, invoicing, reporting and data sync, and run CI/CD for the Odoo and n8n stacks. I also helped migrate about 2 GB of project data, including existing calls, from Bitrix into one production CRM.

• FiatDemise / XMRChat (Jun – Aug 2026), Contract Android & C++ Engineer: completed XMRPod, an AntennaPod fork with Monero tipping, through F-Droid inclusion and 14 releases, and implemented Wayland QR payment scanning for the Monero GUI wallet (C++/Qt).

• Freelance clients (2021 – 2025): Python/FastAPI scraping and automated PDF reports, timesheet and invoice automation, a SvelteKit/FastAPI booking platform, and Node.js/TypeScript trading analytics.

Open source: I created Ziran, a general-purpose programming language and compiler, and Kryon, a UI library written in Ziran. On top of them I ship Inner Breeze, a mindfulness app for Android, Windows, Linux and the web, and Pass, a stateless password generator.

Core stack: Python, TypeScript, Go, C/C++, Rust · n8n, Odoo · Docker, Linux, CI/CD, GitHub Actions · PostgreSQL, MariaDB, Redis · Android, Flutter, React, SvelteKit.

German (native), English (fluent), Czech (conversational) and Spanish (beginner). Based in Asunción, Paraguay (UTC-3), open to remote freelance and contract roles.
