Geri Crroj

Hey! That’s me.

I’m Geri Crroj, an Enterprise Systems Analyst at Niagara Region. I live in the space where the platform meets the people who have to use it — .NET applications, REST APIs, SharePoint, and the Power Platform. Alongside that I run a small consulting practice, TenantCraft.

Before this: Application Analyst at the Region, IT Systems Officer for the Government of Ontario. Advanced Diploma in Computer Programmer & Analysis from Niagara College (2019–2021), specializing in full-stack systems. Microsoft certified — Azure Developer Associate (AZ-204) and Power Platform Fundamentals (PL-900).

My working process.

My process starts before any build: understanding the estate as it actually is, not as the documentation claims. Inventory, interviews, and a hard triage of what deserves to move.

From there it's small, verifiable increments — a wave, a form, a report — each one validated with the people who use it before the next one starts.

Assess & inventory

Every site, form, workflow and integration gets listed and scored by complexity and business value. No plan is credible before this exists.

Triage & plan

Four buckets: archive, migrate as-is, rebuild, retire. Two of them usually never move at all — which is how the timeline becomes realistic.

Build in waves

Small verifiable increments — one wave, one form, one report — each validated with the people who use it before the next begins.

Hand over properly

Documentation, training per wave, and governance that survives after I leave. Nothing depends on me being reachable.

Have questions?

The ones I get asked most, answered plainly.

Both. Assessments and defined projects are fixed fee so you know the number up front. Ongoing help runs through hour banks of 5, 10 or 25 hours — no minimums, no expiry, never open-ended time-and-materials.

That's the normal case. I'm usually the specialist alongside an internal team — I do the SharePoint and Power Platform work, your team keeps ownership, and I document everything so it stays that way.

The assessment takes about five days and produces a phased plan with a costed estimate. Migration itself depends entirely on what the inventory finds — which is exactly why the assessment comes first.

Yes. I work with organizations across Canada and the US through TenantCraft — remote by default, with on-site time only where it genuinely helps.

They get rebuilt, usually in Power Apps or as modern list forms. The submitted data is still sitting there as XML and can be extracted before it's stranded — that's part of the migration, not an afterthought.
