Antti K. Koskela - Microsoft MVP, M365 and Azure Solutions Architect, and the person behind Koskila.net
Welcome to Koskila.net. I am a Finnish software developer entrepreneur living in the countryside, and this is my personal professional blog for documenting solutions that are genuinely useful in real work.
The focus is Microsoft technology, cloud architecture, and enterprise software development, but the spirit is broader than any single stack.
The blog has been online since 2009 and in its current shape since 2015. Over the years, it has grown into a long-running notebook of lessons from consulting projects, architecture work, product implementation, and practical troubleshooting that teams can apply quickly.

Grounding Copilot agents: files or connectors?
This is part 2 of Baby Steps to Copilot Mastery , my multi-part series on useful declarative Microsoft 365 Copilot agents. In part 1 , we looked at why you might choose to build one instead of using Copilot Studio or going all-in with a "real" custom code solution. This time, let's give the agent something useful to talk about 😆 We'll look at SharePoint and files, when to use a Copilot Connector, and what our support-ticket demo actually puts into the index.

Declarative Copilot agents without custom agent code
Coming down from the highs of this year's awesome HELish summit, I figured I'd visit the topic of my talk one more time! We've now presented multiple sessions on the topic with my friend and former colleague Gautam Sheth, and figured I'd address some of the questions and feedback we've gotten in a couple of blog posts. In this first post, I'll explain why declarative Microsoft 365 Copilot agents can take you surprisingly far without you having to write custom agent code or maintaining an agent backend.

Plot twist: Joining Meltlake!
A few weeks ago I wrote about losing my job , which was admittedly a slightly dramatic way to say that my contract with Omnia is now ending. It started to look like I had a lot more calendar availability after September than I had originally planned for. But that particular situation escalated pretty nicely - instead of having to learn goat herding and move to the mountains (which has been my backup plan for quite some time), I might still be able to find gainful employment in a field I actually enjoy working in.- Published on

The person behind the posts
I started freelancing as a web developer at 14, and the fascination never stopped. Today I mainly work as a Solutions Architect at Omnia Intranet, operating at the intersection of architecture strategy and implementation detail.
This site exists to document what works, what fails, and what can be improved in Microsoft-focused engineering work. It is intentionally broad because real-world software problems do not arrive in neat categories.
If you value direct examples, tested fixes, and practical patterns over polished theory, this is the right place to browse.
Elsewhere on the web
This is the main home for Microsoft-focused writing, while ThoughtsOnTech.net covers gadgets and consumer-tech observations. The split keeps each stream focused and easy to follow.
