services

azure virtual desktop & nerdio

Enterprise AVD environments designed and deployed with Nerdio. From architecture through full rollout for large and complex user populations, with performance and cost built in from the start.

azure infrastructure & migrations

Cloud migrations from on-premises or competing platforms to Azure. Full-stack infrastructure design, implementation, and modernization Scoped clearly, executed without surprises.

microsoft 365 & exchange

M365 tenant architecture, Exchange migrations (on-premises and online), SharePoint, and identity. Properly designed, secured, and handed over with documentation your team can actually use.

devops & automation

Azure DevOps, GitHub, GitLab, CI/CD pipelines, Docker, and Kubernetes. Infrastructure automation and deployment pipelines built to reduce manual overhead and improve reliability.

cloud cost optimization

Cloud environments accumulate waste. A structured audit and rearchitecture can eliminate significant ongoing spend without sacrificing performance or reliability.

how we work

discovery & assessment

We start by understanding your environment, goals, and constraints in depth. This means reviewing your current setup, documenting requirements, and identifying risks before any design decisions are made.

architecture & design

We design the target architecture and produce a clear plan: what will be built, how it will be migrated, in what sequence, and why. You have full visibility into the approach before work begins.

implementation

We build and deploy according to the agreed design. Progress is communicated throughout, so your team knows where things stand at every stage and there are no surprises at go-live.

testing & validation

Before cutover, we validate that everything works as designed. Issues are resolved in a controlled environment, not discovered in production. Go-live happens when we're confident it's ready.

handover & closeout

Every engagement closes with full documentation, a knowledge transfer session for your team, and a stabilization period after go-live. The goal is that your team is self-sufficient from day one.

why work with us

planning protects the outcome

Every engagement starts with real planning: clear scope, a defined timeline, and pricing agreed before work begins. That discipline exists because poorly planned projects tend to generate expensive surprises later, and I would rather get the scope right upfront than quietly absorb the cost of fixing it after the fact. You will always know what you are paying for and why.

quick, direct answers

When you need an update, you get one quickly. I respond directly and promptly, not through a ticket queue or account manager, so you are never left wondering where things stand on your project.

explained in plain terms

Technical decisions get explained in plain terms, not buried in jargon or diagrams that need a background to read. Whether or not you have a technical team of your own, you will understand what is being built, why it was chosen, and what it means for your business.

about tech casters

Hi there. I am Chrysillis Collier, founder of Tech Casters and a Cloud Solutions Architect with 20 years in IT and deep specialization in enterprise Microsoft cloud.

What drew me to this field in the first place was curiosity: I like figuring out how systems actually work, and then building something solid that other people can rely on. That is why I gravitated toward infrastructure and sysadmin work specifically, I like building the foundation everyone else gets to work on top of.

I founded Tech Casters to put that experience and curiosity to direct use: focused, project-based engagements for companies that need senior-level work done well, covering migrations, AVD deployments, infrastructure modernization, and DevOps buildouts.

If you have a project in mind, I'd like to hear about it.

have a project in mind?

If you have a cloud migration, AVD deployment, infrastructure modernization, or DevOps project coming up, I'd like to hear about it. The discovery call is a no-obligation 60-minute conversation where we talk through your environment, scope, and goals. No pitch, no pressure.

frequently asked questions

What kinds of projects do you take on?
Migrations from on-premises or competing cloud platforms to Azure, Azure Virtual Desktop deployments, M365 tenant architecture and Exchange migrations, Azure infrastructure design and modernization, DevOps pipeline buildouts, and cloud cost optimization. The common thread is complex Microsoft cloud work that requires a senior architect.
What size companies do you typically work with?
Mid-size and larger organizations. Company size matters less than the scope and complexity of the project. If you have a meaningful cloud infrastructure challenge, the discovery call is the right starting point.
How is work scoped and priced?
All engagements are project-based. We agree on scope, deliverables, and pricing upfront, before any work begins. There is no ongoing retainer requirement. If you are unsure what scope looks like for your situation, the discovery call is where we work that out.
Do you work on-site or remotely?
Both. The majority of cloud infrastructure work is done remotely. For clients in Berlin, on-site is available when needed. For clients elsewhere in Germany or the EU, we handle most work remotely and can arrange on-site for specific situations.
Can you work alongside an existing internal IT team?
Yes. Many engagements involve collaborating with an existing IT team, whether I am leading a migration they will take over, bringing specialist Azure expertise to a project they are managing, or working in parallel on separate workstreams. I am comfortable in that kind of structure.
What does the discovery call cover?
It is a 60-minute conversation where we talk through your environment, the project you have in mind, timeline, and whether it is a good fit. There is no obligation to proceed. You will leave with a clearer picture of options and next steps regardless.
Can you handle large-scale migrations?
Yes. I have led migrations of 4,000+ users across cloud platforms and managed AVD environments for over 2,000 active monthly users. Scale is not a barrier. It is where this kind of work gets interesting.
Do you work exclusively with Microsoft technologies?
Primarily yes. My core expertise is Azure, M365, AVD, and the broader Microsoft stack. I also work with GitHub, GitLab, Docker, Kubernetes, and Linux servers. If your environment is mixed, get in touch and we can talk through what is feasible.
Do I need to have existing cloud infrastructure in place?
No. I work with organizations at any stage: starting from scratch, migrating from on-premises, or already in the cloud and looking to rearchitect or optimize.
Do you work in German or English?
Both. Whichever works best for you and your team is fine.
How quickly can you start a new project?
It depends on current project commitments. The discovery call is the right starting point. From there we can discuss availability and realistic timelines for getting started.
Do you sign NDAs or other agreements?
Yes. NDAs, data processing agreements, and other standard business agreements are not a problem. If you need something in place before the discovery call, let me know in advance and we can sort that out.
