About me
I make sure teams build the right thing.
I'm a Business Analyst / Product Owner with 3+ years across FinTech, Healthcare AI, Industrial Ops, Public Safety and Event SaaS.
Right now I'm the sole BA across multiple concurrent product builds at Tech Exactly, working directly with clients across multiple industries, owning each from discovery and BRD/FSD/SRS through to UAT sign-off as Product Owner.
The results matter more than the documents.
Open to Business Analyst / Product Owner roles where I can own outcomes end to end, ideally with a team shipping products at scale.
Requirements with no loose ends
Discovery, interviews and workshops turned into BRD/FSD/SRS, UML and user stories with airtight acceptance criteria.
End-to-end delivery ownership
Product Owner across multiple live products, backlog, sprint ceremonies, UAT and client sign-off, all the way to a clean release.
Range across industries
Translating ambiguous briefs from clients in FinTech, Healthcare AI, Industrial Ops, Public Safety and Event SaaS into delivery-ready scope for cross-functional teams.
AI-accelerated delivery
Using AI-assisted tools to speed up documentation, validation and requirement analysis without cutting corners.
Proof in data
Power BI, SQL and Excel to validate decisions and show impact, not just opinions.

How I work
From problem to product, in six steps
The same path on every project, so nothing gets lost between the business and the build.
- 01
Problem
Start from the business reality (the friction, the cost, the thing that isn't working) before touching a solution.
- 02
Discovery
Interviews, workshops and stakeholder conversations to surface what people actually need, not just what they ask for.
- 03
Analysis
Structure the ambiguity (process maps, data, edge cases) until the shape of the problem is unmistakable.
- 04
Requirements
BRD / FSD / SRS, UML and user stories with acceptance criteria tight enough to leave no room for interpretation.
- 05
System
Align engineering, QA and stakeholders around one definition of done, and steward every sprint toward it.
- 06
Product
Through UAT to a clean release, then validate the outcome with data and prove the impact.
