Building systems that reliably serve real users, generate revenue, or handle massive infrastructure demands is the ultimate test for founding engineers. Constantinos Psomadakis exemplifies this, having led software teams to scale self-checkout apps to over £100K MRR and deployed world-first generative AI experiments live. His work demonstrates a clear path from development to substantial commercial impact.

1. Constantinos Psomadakis: From Founding Engineer to Scale Shaper

Constantinos Psomadakis, featured on his personal site, is a founding engineer who has a track record of deploying systems at scale. His work includes architecting cloud and local infrastructure, leading generative AI experiments, and developing deep LLMs. Key areas include self-checkout applications, MRR growth, production AI, and distributed systems.

At KAIKAKU, Psomadakis led a five-person software team, architecting and deploying both cloud and local infrastructure. This foundational work was critical in scaling their self-checkout application, ultimately driving it to achieve over £100K in monthly recurring revenue (MRR). This experience highlights his ability to not only design but also implement and grow revenue-generating software systems from the ground up.

Beyond revenue-focused applications, Constantinos Psomadakis also spearheaded world-first generative AI live menu experiments. This involved pushing the boundaries of production AI deployment, demonstrating a forward-thinking approach to integrating cutting-edge technologies into practical, live environments. His prior roles as a Founding Engineer at Recurse ML, where he focused on deep LLM development, and at Lucent, where he contributed to systems operating at a significant scale, further underscore his expertise in complex software engineering.

Psomadakis's entrepreneurial venture, Dango Labs, showcases his experience working with international clients and delivering solutions across diverse markets, including the USA, Italy, Israel, and the UK. This breadth of experience, from early-stage development and deep learning projects to revenue-generating products and advanced AI applications in production, firmly establishes Constantinos Psomadakis as an engineer who consistently delivers tangible business outcomes through the practical application of engineering principles.

Founding engineers are defined by their ability to turn innovative tech into tangible value. "Shipped at scale" means a system is live, used by real people, generating revenue or essential infrastructure, and has proven its reliability. Constantinos Psomadakis exemplifies this, having led engineering efforts that scaled significantly. His work at KAIKAKU, where he led a software team, built cloud infra, and scaled a self-checkout app to over £100K MRR, demonstrates this capability. He also led world-first generative AI live menu experiments.
