Senior tech lead
when it matters.
I support companies as a senior software architect and tech lead, especially when projects become technically complex or teams need additional senior experience. My focus is durable architecture, clean implementation, and systems that remain maintainable.
Senior Software Engineer, App & Full Stack, Software Architect, Fractional CTO support & AI Solution Architect. Vienna, Klagenfurt, remote across Europe and beyond.
Part of your team.
Through to production.
A Forward Deployed Engineer (FDE) works closely with a customer’s team to build and integrate solutions into their existing systems. This is how I support you: from clarifying business requirements through architecture and implementation to production integration.
I connect app, backend, and, where useful, AI components with your data and workflows. Tests, documentation, and handover to your team are part of the work, so the solution remains maintainable.
AI features
with purpose.
As an AI Solution Architect and GenAI Integration Engineer, I design and build AI features where they create tangible product value—not just convincing model demos. My work covers product scoping, LLM integration, deterministic verification, evaluation, and integration into existing app and backend architectures. Depending on the use case, that includes RAG assistants, structured data extraction, offline and on-device models, NLP, and conversational AI.
AI as a tool
with review.
I use Claude Code, OpenAI Codex, and GitHub Copilot deliberately for prototyping, refactoring, tests, documentation, and implementation. The important part remains technical ownership: architecture, review, quality, and a clean handover to the team.
Typical
situations.
Small entries, close to the code.
A look into the codebase: architecture, modules, data flow, build, tests, dependencies, release process, and the areas that will hurt next.
Turn an AI idea into a bounded, testable vertical slice before committing to a full rollout: use case, data boundaries, model integration, verification, evaluation, and production risks.
Temporary hands-on support when app experience is missing in the team: Android, Kotlin, Jetpack Compose, KMP/CMP, reviews, modernization, and implementation.
Technical sparring for founders, product leads, and engineering teams when roadmap decisions, architecture, hiring, vendor choices, or delivery risks need senior ownership.
Use Claude Code, Codex, and GitHub Copilot for prototyping, refactoring, development, and reviews - with clear boundaries, tests, and technical responsibility.
Stabilize existing Android, iOS, Ionic, or cross-platform apps and make them maintainable again step by step.
Tech stack.
Where and how.
I work on a project basis, in interim roles, or as a long-term B2B engagement, supporting existing teams hands-on as a tech lead or senior engineer.
More than 20 years of software development and technical project responsibility, with a focus on architecture, mobile, cloud, and AI. Hourly rate, day rate, and availability on request.
