What clients say

The same theme keeps coming back: understand the process first, automate the part that pays, and leave a human in charge of the decisions that matter.

Fantastic experience working with Valentin. He helped us automate a large part of our customer communication workflow using AI and integrated the solution with our existing internal systems. He quickly understood our business processes, identified where automation would have the biggest impact, and translated our requirements into a reliable working solution. Communication was clear and proactive, iterations were fast, and every milestone was delivered on time. The final system significantly reduced the amount of manual work for our team. Highly recommend and would gladly work with Valentin again.
Ethan ParkerFounder · Flowbridge Systems
I had an outstanding AI automation consulting session with Valentin. He took the time to understand our current workflow, asked thoughtful questions about the way our team handles incoming requests, and clearly explained where AI could realistically improve the process. What stood out was that he didn't try to automate everything blindly — he focused on practical use cases and potential business value. The call gave us a much clearer understanding of how to approach the project, and we're planning to work with him on the implementation.
Marcus BennettCEO · Northpeak Operations
Valentin delivered a well-structured and reliable AI automation prototype for our team. His attention to detail was evident from the beginning. He carefully mapped the workflow, handled edge cases, and made sure the system could be reviewed and controlled by our employees when necessary. Communication was clear, development stayed on schedule, and working together was very straightforward. I would highly recommend Valentin to companies looking to introduce AI into their operational processes without creating unnecessary complexity.
Daniel MercerFounder & CTO · Relaystone Labs
It was an absolute pleasure working with Valentin on the automation of our internal sales workflow. From the initial discussions to the final implementation, he demonstrated strong technical expertise, professionalism, and a very good understanding of business processes. He was able to turn our rather fragmented requirements into a clear workflow where AI handles repetitive tasks while our team remains in control of important decisions. The result was practical, easy to use, and fit naturally into the way our team already worked.
Adrian ColeFounder · Vertexlane Software
Straight 5-star cooperation. Valentin was easy to work with, clear in communication, supportive throughout the project, and delivered everything we agreed on — plus several improvements we hadn't initially considered. The AI automation worked exactly as expected and integrated smoothly with our existing tools. He was also very responsive whenever we needed adjustments. Would definitely work with him again.

§ 03 / Services

What I do

Three directions — from wiring one AI feature into an existing flow to end-to-end automation of an operational process.

01

AI-powered process automation

I put AI into real operational workflows: inbound email, RFQs, technical documents, back-office.

02

Custom agents & integrations

Agents built around your actual process — prototype on real data first, production pipeline second.

03

Consulting & team training

Where AI actually pays off in your operation — and how your team runs it once I hand it over.

§ 04 / Niches

Who I help

Complex B2B processes with heavy manual work across mailboxes, documents and legacy systems.

§ 06 / Fully integrated

Built to work with your systems

Automation runs across the tools you already have, connecting data, workflows and systems into a single operational layer. You never have to migrate off your stack — the pipeline meets it where it is, through the APIs and databases it already exposes.

§ 07 / Bio

About me

7 years in IT, the last three focused on AI-powered business automation — putting AI into real operational processes: email, RFQs, PDFs, spreadsheets, CRM, ERP and internal databases.

I work with complex B2B niches full of manual, repetitive work — procurement, logistics, supply chain, distribution and resellers. My approach is simple: instead of flashy demos I deliver working pipelines integrated into existing systems, with a metric attached.

Anything touching a price or an order gets a human checkpoint and a confidence threshold — automation that guesses quietly is worse than none.

§ 08 / Method

How I work

Five steps from the first call to a system that runs itself.

01

Process audit

as-is

We map the workflow as it really runs today — tools, hand-offs, and where time and accuracy leak.

02

Pick the use-case

discover

Together we pick the highest-leverage spot where AI actually pays off — not where it looks impressive.

03

Working slice

build

One real end-to-end path on your real data — the ugliest twenty examples first, so we find the breaking points early.

04

Integration

wire

Wired into your stack: mail, CRM, ERP, databases, queues and monitoring, with alerting on the exception path.

05

Rollout & hand-over

ship

Your infrastructure, your keys, a handover doc and a walkthrough recording. Nothing that needs me around to keep running.
