Max Trifonov, M.Sc. Full-Stack AI Engineer LLM integration and automation Based in Düsseldorf, Germany, working remotely
I build AI that makes it into production. And keeps running there.
Plenty of companies have introduced AI, few use it day to day. I automate recurring workflows and bring AI into the systems you already use, up to reviewing customer conversations, and I keep everything running reliably.
- 20,000+ automated conversation analyses
- 2,000+ new transcripts every month
- 17 live services and systems built
- Voice AI for real-time conversations
Why it pays off
Time
Follow-up, notes and moving data between systems happen automatically. People stay focused on the conversation.
Skills shortage
Unfilled positions cost the German economy around 49 billion euros in lost output in 2024.1 Automation takes load off the team you already have.
Fewer errors
Data moves between systems without retyping, and every step is logged.
AI that actually runs
57 percent of German companies use AI, yet only 3 percent say they are making strong use of its potential.2
When it is not worth it
- Rare tasks: anything that only comes up a few times a month is cheaper by hand.
- No fixed process: without clear steps, there is nothing that can be reliably automated or measured. Process first, then AI.
- Decisions about people: a person makes the final call. AI does not take responsibility off anyone's shoulders.

For companies in any industry where work repeats itself: automating workflows, bringing AI into existing systems and, where customer conversations happen, reviewing those too.
Workflow automation
Generate documents, sort emails and move data between systems, with n8n or custom code.
AI in your existing systems
API integrations, production monitoring and hosting in the EU.
Conversation analytics
Automatically review sales, advisory or service calls, with a clear rationale for every result.
Voice AI and training
Simulate conversations in real time, so your team can practice without real customers.
Projects
What each system does and the stack behind it.
-
20,000+
analyses, 2,000+ transcripts a month
AI conversation analysis
Automatically reviews advisory calls against the conversation guide: what was covered and where things went wrong. Team leads see the results for their team, for every call instead of a few spot checks.

Automated
documents, forms, workflows
Automation
Generates documents from customer data, fills in forms, applications and calculators, and runs recurring workflows in the background, saving hours of routine work.
Stack Python, Selenium, n8n

Real-time
voice conversations with AI customers
AI call training assistant
Advisors practice phone calls with AI customers who respond like real people, and get feedback after every call. New advisors practice before they talk to real customers.

Documents

AI document service
Extracts information from documents and produces an evaluation that a person reviews before it is used.
Stack Python, FastAPI
Confidentiality and privacy
Confidential
Client projects, documents, data and agreements stay confidential, which is why you won't find any names here. Every engagement starts with a non-disclosure agreement.
Privacy by design
Customer and employee data is processed only as far as the purpose requires. Access on a need-to-know basis, EU hosting wherever possible, lean logs with short retention, and a data processing agreement with every provider.
Built to the EU AI Act
Every system I build follows the EU AI Act. Risk classification and obligations are settled before development starts, with transparency for everyone involved and human oversight. When AI evaluates conversations or employees, a person makes the final call.
Fair to the people being assessed
When AI assesses people, every result has to be explainable and verifiable. Safeguards against unfair or incorrect results are built into the system.
How I work
Documentation is part of the deliverable
Architecture, decisions, runbooks and rollback procedures are written down and kept current. Whoever takes over understands what was built and why.
Traceable
Every AI result comes with its reasoning and evidence. Every change is logged and can be traced back.
Thorough
Measure first, then make claims. I come from biomedical research, so every claim about an AI system needs data behind it, and every major change is independently reviewed and tested before release.
Operations included
Monitoring, alerting, and a way back when something goes wrong.
Clear recommendations, not a list of options
I tell you what I would do, and why.
Both sides of the table
I have worked as an advisor myself, so I know the conversations my systems analyze.
