About

Professional summary

I am a software and systems engineer focused on DevOps, automation, backend services, and full-stack application development. I build products and operational systems from requirements through implementation, testing, deployment, and long-term maintenance.

I have been programming since age 13 and have contributed to open-source software since 2016. My work includes language and compiler tooling, UI libraries, Android and native applications, ERP integrations, real-time analytics, reporting systems, and business workflow automation.

I work extensively with Python, TypeScript, C++, Go, Rust, Docker, Linux, CI/CD, PostgreSQL, and API-driven systems. I am experienced in building reliable integrations between Odoo, n8n, external APIs, data services, and deployment environments.

As a freelance engineer since 2021, I have delivered projects for German and international clients across scraping, reporting, automation, trading analytics, booking platforms, web applications, and game-related products. I am comfortable owning both technical architecture and hands-on implementation.

I also develop independent open-source projects, including the Ziran programming language and compiler, the Kryon UI library, and cross-platform applications built for Android, desktop, Linux, and the web. I care about practical usability, offline-first design, accessibility, and maintainable release processes.

I am a German national based in Asunción, Paraguay, working remotely in UTC-3. I can overlap effectively with European working hours and am open to remote freelance opportunities.

Career history

DevOps Engineer & Odoo Specialist Erfolgswerk.ai (Aurea Momentum Ltd.)

I automate end-to-end order processing through n8n pipelines that connect Odoo ERP with external services and APIs. This work replaces manual processes across sales, invoicing, and reporting workflows.

I develop custom Odoo modules and plugins for sales, invoicing, reporting, and data synchronization. I also build CI/CD pipelines for Odoo and n8n deployments and supported the migration of approximately 2 GB of Bitrix data into a unified production CRM.

Android & C++ Engineer FiatDemise (XMRChat / Monero ecosystem)

I develop XMRPod, an AntennaPod fork that supports Monero tipping for XMRChat. My work includes F-Droid inclusion, first-run tracking disclosure, fastlane metadata, release management, and upstream AntennaPod rebases.

I built the USD/XMR tipping flow, podcast and API matching, wallet handoff, source-attributed superchats, and TalkBack accessibility labels. I also implemented Wayland QR payment scanning and multi-recipient payment URIs for the Monero GUI wallet using C++ and Qt.

Freelance Software Engineer - Full-Stack & Automation Self-employed

I delivered full-stack, automation, data, and deployment projects for international clients. For MaverickEye UG, I built Python and FastAPI scraping and data-collection services, improved MariaDB schemas, and produced automated PDF reports with secure delivery.

Other client work included timesheet and invoice automation, Python data-transformation pipelines, Docker deployments, a Hugo website redesign, a SvelteKit and FastAPI booking platform, and Node.js/TypeScript trading analytics with REST and WebSocket APIs. I also developed HTML5 and Telegram games, Web3 integrations, React applications, Solidity components, and the Godot game Geocats as sole developer.
