Thomas Varekamp · Freelance AI Engineer
I help companies build practical AI applications using LLMs, agents, business data and existing systems. From prototype to production, I work directly with your team.

AI applications
Internal copilots, knowledge assistants and purpose-built applications using language models.

Agents & automation
Agents that retrieve information, perform calculations, use APIs and support workflows across systems.

Business knowledge
Connect models to documents, databases and internal knowledge so answers are relevant and verifiable.

Data & integrations
APIs, databases, data platforms and business applications connected into one usable AI workflow.

"We were managing data manually, disconnected from business outcomes. After Drilldown's analysis, it finally clicked – we could clearly see how a single strategic decision directly impacted the bottom line."
"After trying different tools for a year without success, Drilldown delivered the insights we needed in just 4 weeks. This new setup helps us track our business clearly, making it easier to reach our goals."
"What impressed me was how Drilldown turned complex analytics planning into a clear, actionable strategy. They understood our needs quickly and delivered a pragmatic roadmap that gives us a strong foundation for growth."
"Everyone looked at different numbers, making it impossible to agree on what truly mattered. The collaboration aligned us around shared data and opened our eyes to which metrics truly drive the business."
"Our previous data setup wasn't scalable, making data-driven growth hard. Drilldown built the solid foundation we needed, giving us the confidence to scale smarter."
"We lacked a clear way to see the business numbers that truly matter. Drilldown built a dashboard that makes our key metrics easy to understand and use, helping us make better decisions and improve how we run the business."
"We needed dashboards that gave us the right insights in a clear and usable way. Drilldown delivered thoughtful, good-looking dashboards that provide the deep insights we need while staying easy to use."
"We wanted a straightforward dashboard to match our simple CRM, but didn’t have one. Drilldown delivered exactly that, a smooth process, spot-on result."

Yes. I can own a defined AI application or join an existing software, data or AI team as additional engineering capacity.
Primarily practical business applications using LLMs, agents, RAG, APIs and company data. The focus is on building useful software around real business processes rather than training foundation models.
Yes. I can review the existing prototype, architecture and data flows and help turn it into a more reliable application with appropriate testing, integrations, access controls, monitoring and guardrails.
That's often part of the work. My background is in data architecture and analytics, so I can also build or improve the data layer required for the AI application.
Usually 2–4 days per week, either independently on a defined project or embedded in your existing team. On-site, hybrid or remote arrangements are possible.
Let's discuss what you're trying to build, where your team currently stands and whether I can help move it forward.
