Cover image for GA4 Attribution Framework — Demand
GA4 Attribution Framework — Demand Creation vs Demand Capture Analysis Developed a GA4-based attribution framework to separate demand creation from demand capture across channels. Mapped each channel’s business role (Organic, Paid Search, Performance Max, Direct, Referral) and translated attribution insights into concrete optimization actions — including where to scale, where to constrain spend, and which channels should be treated as structural. This framework helps service businesses avoid over-investing in demand-capture channels while underfunding true growth drivers.

Cover image for A clean-looking spreadsheet can still
A clean-looking spreadsheet can still hide a broken record trail. For this synthetic cleanup concept, I used four small rows so every correction could be traced: — 2026-07-03 and Jul 03 2026 resolve to one duplicate — Excel serial 46208 resolves to 2026-07-05 — the formula error is repaired without changing the valid rows — source count, removed duplicate, and normalized output reconcile in the QA ledger The signature element is the checksum seam. It keeps the raw rows visibly connected to the normalized table, because cleanup should preserve provenance rather than replace messy data with an unexplained polished sheet. This is self-initiated concept work built with plausible synthetic data, not a client result. It demonstrates a small, reviewable before/after workflow for spreadsheet cleanup and data-quality checks. Case study: https://contra.com/p/E7q7lFF3-concept-traceable-spreadsheet-cleanup

Cover image for Design-to-code handoff becomes fragile when
Design-to-code handoff becomes fragile when the mapping disappears between the component and the browser. For this concept workflow, I kept the implementation evidence connected from source to output: — the component anatomy stays tied to semantic HTML — the 24 px spacing token becomes --space-6: 24px — the primary CTA remains a real <a href="#scope"> link — the same structure is checked at 1440, 1024, and 390 px The signature element is the mapping spine. It links each Figma decision to its DOM, CSS, and responsive proof, making the handoff inspectable instead of presenting a generic “design turns into code” montage. This is self-initiated concept work using synthetic content, not a client result. It demonstrates the evidence trail I use when translating a supplied Figma landing page into responsive HTML and CSS.
