Hello, I’m Thomas Rasshofer

I’m an interdisciplinary engineer with a passion for design who builds digital products, services, and experiences that delight people – and, increasingly, the AI systems and agentic workflows behind them.

Senior, hands-on, and AI-native, I work across engineering, design, and product as a one-person team and orchestrate fleets of agents where they create real leverage, while staying accountable for direction, judgment, and quality. Initiative over permission, ownership over delegation, outcomes over tickets.

What matters most is AI that holds up in production, not just in a demo: a clear integration shape, sound agent architecture and orchestration, evaluation strategies and guardrails, and prompts and context treated as code. And since the AI landscape keeps shifting underneath every project, I build for inheritance – with replaceable layers, documented decisions, and teams that can carry on without me.

Driven by curiosity and devoted to excellence, I take ideas from napkin sketch to shipped product. Fast-paced environments, tight deadlines, and going the extra mile are my personal comfort zone.

Before becoming a full-time freelancer, I was working as Principal Engineer for SinnerSchrader (part of Accenture Interactive) at the intersection of consulting and software engineering, assisting global brands to design and develop cutting-edge digital products and services to solve business problems, improve processes, and introduce new products to market in a scalable, performant, observable, and secure manner. Today, I bring the same rigor to AI-native product engineering: from LLM integrations, agents, and retrieval pipelines to helping organizations rethink how they work, so small, focused teams can move faster than their size would suggest.

I never worked at Apple and Google but I’m renowned for using their products every day. Besides that I have a strong partnership with Spotify as I use it to listen to most of my music. Also, I’ve been recognized as one of the best Coca Cola drinkers and I really loved to go for a spin in my Audi while I was waiting for my Tesla to arrive.

But seriously: In the last couple of years, I’ve been lucky enough to collaborate with leading brands such as Telefónica/O₂, BMW, Rolls-Royce, MINI, ADAC, ProSiebenSat.1, ABB, Allianz, Malteser, EnBW, Contentful, Volkswagen, Audi, and Helsing to name a few. The mission has always stayed the same: to create great digital products together with great people and have fun along the way.
