Lars Keller

IT Project Lead · Software Engineer · Founder of DeLake

I lead software projects that must not fail – and build them with my own development team.

In brief

Lars Keller is an IT project lead, software engineer and founder of DeLake LTD in Larnaca, Cyprus (EU). For more than seven years he has been responsible for software projects in SaaS, healthcare IT and regulated B2B environments – as project lead, Scrum Master and Product Owner. At DeLake he combines project leadership with delivery through a permanent in-house development team, working remotely for clients across DACH, Benelux and Europe, in German and English.

My name is Lars Keller. For more than seven years I have worked in software development and IT project management: as project lead, Scrum Master and Product Owner on SaaS products, in healthcare IT around the German Gematik telematics infrastructure, and in regulated B2B environments where compliance and traceability are non-negotiable.

With DeLake LTD in Larnaca, Cyprus, I turned that into my own company – inside the EU legal framework, working remotely for DACH, Benelux and Europe. What sets it apart from classic consulting: I don't just deliver concepts, I deliver code. Behind every project stands a permanent, well-rehearsed development team that actually builds the web apps, SaaS platforms and AI features.

What drives me is translation – between management and engineering. Cutting requirements so teams can actually implement them. Naming budgets and deadlines honestly instead of talking them down. And using AI where it measurably improves daily work and software – GDPR-compliant, with security first.

Project leadership, software development, AI integration

Leadership and delivery – from one hand.

Four things companies bring me in for. Usually it starts with a project that has been stuck for a while.

IT project leadership

External project leadership for software initiatives: requirements engineering, technical roadmaps, stakeholder management, controlling and reporting. Agile with Scrum, classic or hybrid – whatever your environment can carry.

Software engineering

Web apps and SaaS products with Angular, TypeScript and Flutter, plus API design, system architecture and DevOps. I write code myself and review my team's – which is why the estimates stay realistic.

AI integration

AI features in existing and new software: assistants, document workflows, process automation. Always with clear data rules defined up front, never as an end in itself.

Training & coaching

Hands-on IT training for teams – software architecture, project management, Jira and Confluence, IAM/Keycloak, AI at work. On site, online or as a monthly flat rate.

What I work with every day.

No buzzword bingo – just what is actually inside my projects.

Where I have worked.

From telematics infrastructure to a regulated financial exchange – industries where mistakes get expensive.

Healthcare IT & Gematik

Project leadership inside the German telematics infrastructure: ePA, KIM and TI-Messenger – with the security and approval requirements that come with it.

Regulated financial markets

Document and contract management at a regulated financial exchange – documented audit-proof and delivered on schedule.

Waste management

SaaS platform for municipal waste operators in Germany and Switzerland – from concept through development into live operations.

Dental & MedTech

B2B ordering and cloud software for dental laboratories: interfaces, workflows and data handling to industry standard.

Holiday rentals & travel

Booking platform with CMS and channel integration – from MVP to a scaling platform.

IT consulting & Atlassian

Process consulting, Jira and Confluence rollouts, project steering – structures teams actually use afterwards.

Happy to share further references and project details in a call.
