Freelance practiceFreelance business architecture: Power BI dashboards, semantic models, DAX, Power Query pipelines, row- and object-level security, and Power Automate workflows that retire the manual work nobody wants to own. I stay through the last mile — the slide deck that makes the number make sense to a stakeholder.
Independent recruitingA recruiter without an industry or a company attached. I meet young professionals who are being overlooked in a brutal market, learn what they're genuinely good at, and introduce them to founders and hiring teams who need exactly that. No fee, no funnel — just a network built one honest conversation at a time.
Analytics by trade.
Connector by instinct.
I'm a BSBA graduate from Northeastern University — Business Analytics major, Data Science minor — with a deep interest in sharpening how companies report, decide, and automate the manual work that quietly eats their week.
Alongside that, I have a genuine obsession with meeting new people: understanding someone's skill set, passions, and prospects, then helping them find their professional match. The market is brutal right now, and an entire population of talented young professionals is being overlooked. I want to know them — and I want to know the recruiters and founders looking for a real performer.
Where I'm heading: business strategy and consulting on a company's BI stack, informed as much by market, industry, and finance research as by the data model itself.
Engagements run from a single dashboard rebuild to an end-to-end reporting architecture with automation and enablement wrapped around it.
Certified dashboard design and build — from blank canvas to a report leadership opens every Monday.
Measure logic, time intelligence, and star-schema models that stay fast as the data grows.
Transformation pipelines that turn messy exports into a source you can actually rely on.
Row-level and object-level security so the right person sees exactly the right slice.
Microsoft Fabric and BI-stack guidance: what to centralize, what to retire, what to build next.
Power Automate flows that remove the recurring manual task instead of documenting it.
Insight presented the way decision-makers need to receive it — clear, sourced, and short.
Translating technical findings for non-technical audiences without flattening the nuance.
Project summaries, KPI decks, and the written framing that makes work legible.
Sitting between data teams and business stakeholders so both sides ship the same thing.
A report is only finished when someone who
doesn't work in the data can act on it.

Client work lives behind NDAs, so these are representative mockups — the report layouts I design and the query, measure, and transformation patterns I write.
