For the team
Workshops and training with customers, requirements clearly documented.
Hi, I’m Sebastian Hồ!
Solution Architect | ERP & System Integration | Microsoft Platform
I orchestrate systems, data and people around Microsoft Business Central.
I build data and integration solutions that run reliably — and land with the teams who use them. Freelance, for companies on Business Central and for Microsoft and BC partners.
Orchestrator
A conductor doesn’t play every instrument.
But they know them all and make sure they sound right together. That’s my job.
Business Central sits at the centre. I connect it to everything else you run and get systems, data and people working to the same beat.
-
Systems
Tools, data and processes, finally aligned
Business Central at the centre, connected to CRM, shop, accounting, shipping and your specialist systems. Fewer silos, clearer ownership.
-
Data
Decisions you can trust
Clean data flows and stable interfaces. Reporting becomes dependable, and nobody has to ask which number is actually correct.
-
Decisions
The right logic in the right place
AL, Power Automate or n8n? I tell you where each piece of logic belongs, and why. That keeps the solution maintainable.
-
People
Adoption that lasts
Workshops, training and plain language. New systems get used, the support load drops, and your team works with the system instead of against it.
Work sample
From cable chaos to an orchestra.
This is a typical landscape around Business Central. Build your own and switch between the two.

What I focus on
Four ways in, one goal: a system landscape that plays in tune.
What does it cost?
No two engagements are alike, so I don’t publish flat prices online. What matters to me is that scope, effort and budget work for both sides. After a short look at your situation, you’ll get an honest assessment of scope, priorities and cost.
BC integration & solution consulting
Focus: Business Central as the core of your system landscape, cleanly connected across the Microsoft ecosystem.

About me
Solid architecture needs strong roots
My path began in a trade: take things apart, understand them, put them back together so they run reliably. That’s how I still work today as a Solution Architect, on Business Central and everything connected to it.
Business Central, integrations or AI agents: I never see just the software. I see the people who have to work with it every day.
The mark in my logo is the ồ from my surname, drawn as a knot. It stands for what I build: connections that hold.
This is my tech stack
ERP & business systems
Integration & automation
Microsoft Platform
AI & agents
Data & analytics
Development
Cloud & DevOps
Processes & documentation
Governance & security
What drives me, and what that means for you:
I’m an “assertive mediator” (INFP-A). Sounds like personality-test talk, but in IT work it has real business value.
-
I translate
I speak developer language and business language. Clear communication is where good implementation starts.
-
I stay calm
Rollouts are stressful. When it gets rough, I’m your anchor.
-
I build acceptance
The best software is useless if the team rejects it. I ask how your people work today and build the training around that.
-
I build solutions that work and stay
With technical sense, strategic foresight and human instinct. Let’s build together.

FAQ
So tell me, ...
What does a Solution Architect actually do?
They make sure your systems fit together: functionally, technically and in daily work. The result isn’t a pretty diagram but a setup that runs more smoothly. Fewer workarounds, more reliable numbers, and teams that work with the system instead of against it.
Who do you work for?
As a freelancer, for companies on Business Central or heading there, and for Microsoft and BC partners who need a Solution Architect or consultant on the team. Also as a subcontractor.
Do you only advise, or do you build too?
Both. I design the solution, build integrations and data flows and support the rollout. My work doesn’t stop at the concept. It goes all the way into production.
What don’t you do?
I design and build solutions and bring them to the team. Schedules and status meetings stay with you or your partner. That lets me focus on the technology and the people.
Our systems have grown over the years. Does everything have to go?
Usually not. The best path is often a clear consolidation: what stays, what goes, what gets integrated properly. One thing at a time.
AL, Power Automate or n8n: what do I use for what?
It depends on where the logic belongs. Business logic usually lives in AL, processes around Microsoft 365 suit Power Automate, and n8n plays to its strengths when several systems are involved and you want to self-host.
What does AI-ready mean in practice?
Clean APIs, stable data flows and clear ownership. Without those, AI agents run into chaos and return chaos. The AI strategy workshop shows where you stand in 2 to 4 hours.
Remote or on site?
Both. Remote works very well for most topics. For workshops and critical phases I’m happy to come by, in the Hamburg area and across Germany.
